ОглавлениеAgain, let a man of cheerful disposition, and of a cultivated but not very fastidious taste, observe his own emotions and the countenances of those around him during the representation of a clever tragedy and of a clever farce, and it is probable that he will come to the conclusion that his enjoyment in the latter case has been both more unmingled and more intense than in the former. He has felt no lassitude, he has not endured the amount of pain that necessarily accompanies the pleasure of pathos, he has experienced a vivid, absorbing pleasure, and he has traced similar emotions in the violent demonstrations of his neighbours. Yet he will readily admit that the pleasure derived from the tragedy is of a higher order than that derived from the farce. Sometimes he will find himself hesitating which of the two he will choose. The love of mere enjoyment leads him to the one. A sense of its nobler character inclines him to the other.
A similar distinction may be observed in other departments. Except in the relation of the sexes, it is probable that a more intense pleasure is usually obtained from the grotesque and the eccentric, than from the perfections of beauty. The pleasure derived from beauty is not violent in its nature, and it is in most cases peculiarly mixed with melancholy. The feelings of a man who is deeply moved by a lovely landscape are rarely those of extreme elation. A shade of melancholy steals over his mind. His eyes fill with tears. A vague and unsatisfied longing fills his soul. Yet, troubled and broken as is this form of enjoyment, few persons would hesitate to pronounce it of a higher kind than any that can be derived from the exhibitions of oddity.
If pleasures were the sole objects of our pursuit, and if their excellence were measured only by the quantity of enjoyment they afford, nothing could appear more obvious than that the man would be esteemed most wise who attained his object at least cost. Yet the whole course of civilisation is in a precisely opposite direction. A child derives the keenest and most exquisite enjoyment from the simplest objects. A flower, a doll, a rude game, the least artistic tale, is sufficient to enchant it. An uneducated peasant is enraptured with the wildest story and the coarsest wit. Increased cultivation almost always produces a fastidiousness which renders necessary the increased elaboration of our pleasures. We attach a certain discredit to a man who has retained those of childhood. The very fact of our deriving pleasure from certain amusements creates a kind of humiliation, for we feel that they are not in harmony with the nobility of our nature.107
Our judgments of societies resemble in this respect our judgments of individuals. Few persons, I think, who have compared the modes of popular life in stagnant and undeveloped countries like Spain with those in the great centres of industrial civilisation, will venture to pronounce with any confidence that the quantum or average of actual realised enjoyment is greater in the civilised than in the semi-civilised society. An undeveloped nature is by no means necessarily an unhappy nature, and although we possess no accurate gauge of happiness, we may, at least, be certain that its degrees do not coincide with the degrees of prosperity. The tastes and habits of men in a backward society accommodate themselves to the narrow circle of a few pleasures, and probably find in these as complete satisfaction as more civilised men in a wider range; and if there is in the first condition somewhat more of the weariness of monotony, there is in the second much more of the anxiety of discontent. The superiority of a highly civilised man lies chiefly in the fact that he belongs to a higher order of being, for he has approached more nearly to the end of his existence, and has called into action a larger number of his capacities. And this is in itself an end. Even if, as is not improbable, the lower animals are happier than man,108 and semi-barbarians than civilised men, still it is better to be a man than a brute, better to be born amid the fierce struggles of civilisation than in some stranded nation apart from all the flow of enterprise and knowledge. Even in that material civilisation which utilitarianism delights to glorify, there is an element which the philosophy of mere enjoyment cannot explain.
Again, if we ask the reason of the vast and indisputable superiority which the general voice of mankind gives to mental pleasures, considered as pleasures, over physical ones, we shall find, I think, no adequate or satisfactory answer on the supposition that pleasures owe all their value to the quantity of enjoyment they afford. The former, it is truly said, are more varied and more prolonged than the latter but on the other hand, they are attained with more effort, and they are diffused over a far narrower circle. No one who compares the class of men who derive their pleasure chiefly from field sports or other forms of physical enjoyment with those who derive their pleasure from the highest intellectual sources; no one who compares the period of boyhood when enjoyments are chiefly animal with early manhood when they are chiefly intellectual, will be able to discover in the different levels of happiness any justification of the great interval the world places between these pleasures. No painter or novelist, who wished to depict an ideal of perfect happiness, would seek it in a profound student. Without entering into any doubtful questions concerning the relations of the body to all mental states, it may be maintained that bodily conditions have in general more influence upon our enjoyment than mental ones. The happiness of the great majority of men is far more affected by health and by temperament,109 resulting from physical conditions, which again physical enjoyments are often calculated to produce, than by any mental or moral causes, and acute physical sufferings paralyse all the energies of our nature to a greater extent than any mental distress. It is probable that the American inventor of the first anæsthetic has done more for the real happiness of mankind than all the moral philosophers from Socrates to Mill. Moral causes may teach men patience, and the endurance of felt suffering, or may even alleviate its pangs, but there are temperaments due to physical causes from which most sufferings glance almost unfelt. It is said that when an ancient was asked “what use is philosophy?” he answered, “it teaches men how to die,” and he verified his words by a noble death; but it has been proved on a thousand battle-fields, it has been proved on a thousand scaffolds, it is proved through all the wide regions of China and India, that the dull and animal nature which feels little and realises faintly, can meet death with a calm that philosophy can barely rival.110 The truth is, that the mental part of our nature is not regarded as superior to the physical part, because it contributes most to our happiness. The superiority is of a different kind, and may be intelligibly expressed by the epithets higher and lower.
And, once more, there is a class of pleasures resulting from the gratification of our moral feelings which we naturally place in the foremost rank. To the great majority of mankind it will probably appear, in spite of the doctrine of Paley, that no multiple of the pleasure of eating pastry can be an equivalent to the pleasure derived from a generous action. It is not that the latter is so inconceivably intense. It is that it is of a higher order.
This distinction of kind has been neglected or denied by most utilitarian writers;111 and although an attempt has recently been made to introduce it into the system, it appears manifestly incompatible with its principle. If the reality of the distinction be admitted, it shows that our wills are so far from tending necessarily to that which produces most enjoyment that we have the power even in our pleasures of recognising a higher and a wholly different quality, and of making that quality rather than enjoyment the object of our choice. If it be possible for a man in choosing between two pleasures deliberately to select as preferable, apart from all consideration of consequences, that which he is conscious gives least enjoyment because he recognises in it a greater worthiness, or elevation, it is certain that his conduct is either wholly irrational, or that he is acting on a principle of judgment for which 'the greatest happiness' philosophy is unable to account. Consistently with that philosophy, the terms higher and lower as applied to different parts of our nature, to different regions of thought or feeling, can have no other meaning than that of productive of more or less enjoyment. But if once we admit a distinction of quality as well as a distinction of quantity in our estimate of pleasure, all is changed. It then appears evident that the different parts of our nature to which these pleasures refer, bear to each other a relation of another kind, which may be clearly and justly described by the terms higher and lower; and the assertion that our reason reveals to us intuitively and directly this hierarchy of our being, is a fundamental position of the greatest schools of intuitive moralists. According to these writers, when we say that our moral and intellectual is superior to our animal nature, that the benevolent affections are superior to the selfish ones, that conscience has a legitimate supremacy over the other parts of our being; this language is not arbitrary, or fantastic, or capricious, because it is intelligible. When such a subordination is announced, it corresponds with feelings we all possess, falls in with the natural course of our judgments, with our habitual and unstudied language.
The arguments that have been directed against the theory of natural moral perceptions are of two kinds, the first, which I have already noticed, being designed to show that all our moral judgments may be resolved into considerations of utility; the second resting upon the diversity of these judgments in different nations and stages of civilisation, which, it is said, is altogether inexplicable upon the supposition of a moral faculty. As these variations form the great stumbling-block in the way of the doctrine I am maintaining, and as they constitute a very important part of the history of morals, I shall make no apology for noticing them in some detail.
In the first place, there are many cases in which diversities of moral judgment arise from causes that are not moral, but purely intellectual. Thus, for example, when theologians pronounced loans at interest contrary to the law of nature and plainly extortionate, this error obviously arose from a false notion of the uses of money. They believed that it was a sterile thing, and that he who has restored what he borrowed, has cancelled all the benefit he received from the transaction. At the time when the first Christian moralists treated the subject, special circumstances had rendered the rate of interest extremely high, and consequently extremely oppressive to the poor, and this fact, no doubt, strengthened the prejudice; but the root of the condemnation of usury was simply an error in political economy. When men came to understand that money is a productive thing, and that the sum lent enables the borrower to create sources of wealth that will continue when the loan has been returned, they perceived that there was no natural injustice in exacting payment for this advantage, and usury either ceased to be assailed, or was assailed only upon the ground of positive commands.
Thus again the question of the criminality of abortion has been considerably affected by physiological speculations as to the time when the fœtus in the womb acquires the nature, and therefore the rights, of a separate being. The general opinion among the ancients seems to have been that it was but a part of the mother, and that she had the same right to destroy it as to cauterise a tumour upon her body. Plato and Aristotle both admitted the practice. The Roman law contained no enactment against voluntary abortion till the time of Ulpian. The Stoics thought that the infant received its soul when respiration began. The Justinian code fixed its animation at forty days after conception. In modern legislations it is treated as a distinct being from the moment of conception.112 It is obvious that the solution of such questions, though affecting our moral judgments, must be sought entirely outside the range of moral feelings.
In the next place, there is a broad distinction to be drawn between duties which rest immediately on the dictates of conscience, and those which are based upon positive commands. The iniquity of theft, murder, falsehood, or adultery rests upon grounds generically distinct from those on which men pronounce it to be sinful to eat meat on Friday, or to work on Sunday, or to abstain from religious assemblies. The reproaches conscience directs against those who are guilty of these last acts are purely hypothetical, conscience enjoining obedience to the Divine commands, but leaving it to reason to determine what those commands may be. The distinction between these two classes of duties becomes apparent on the slightest reflection, and the variations in their relative prominence form one of the most important branches of religious history.
Closely connected with the preceding are the diversities which result from an ancient custom becoming at last, through its very antiquity, or through the confusion of means with ends, an object of religious reverence. Among the many safeguards of female purity in the Roman republic was an enactment forbidding women even to taste wine, and this very intelligible law being enforced with the earliest education, became at last, by habit and traditionary reverence, so incorporated with the moral feelings of the people, that its violation was spoken of as a monstrous crime. Aulus Gellius has preserved a passage in which Cato observes, “that the husband has an absolute authority over his wife; it is for him to condemn and punish her, if she has been guilty of any shameful act, such as drinking wine or committing adultery.”113 As soon as the reverence for tradition was diminished, and men ventured to judge old customs upon their own merits, they were able, by steadily reflecting upon this belief, to reduce it to its primitive elements, to separate the act from the ideas with which it had been associated, and thus to perceive that it was not necessarily opposed to any of those great moral laws or feelings which their consciences revealed, and which were the basis of all their reasonings on morals.
A confused association of ideas, which is easily exposed by a patient analysis, lies at the root of more serious anomalies. Thus to those who reflect deeply upon moral history, few things, I suppose, are more humiliating than to contrast the admiration and profoundly reverential attachment excited by a conqueror, who through the promptings of simple vanity, through love of fame, or through greed of territory, has wantonly caused the deaths, the sufferings, or the bereavements of thousands, with the abhorrence produced by a single act of murder or robbery committed by a poor and ignorant man, perhaps under the pressure of extreme want or intolerable wrong. The attraction of genius and power, which the vulgar usually measure by their material fruits, the advantages acquired by the nation to which he belongs, the belief that battles are decided by providential interference, and that military success is therefore a proof of Divine favour, and the sanctity ascribed to the regal office, have all no doubt conspired to veil the atrocity of the conqueror's career; but there is probably another and a deeper influence behind. That which invests war, in spite of all the evils that attend it, with a certain moral grandeur, is the heroic self-sacrifice it elicits. With perhaps the single exception of the Church, it is the sphere in which mercenary motives have least sway, in which performance is least weighed and measured by strict obligation, in which a disinterested enthusiasm has most scope. A battle-field is the scene of deeds of self-sacrifice so transcendent, and at the same time so dramatic, that in spite of all its horrors and crimes, it awakens the most passionate moral enthusiasm. But this feeling produced by the thought of so many who have sacrificed their life-blood for their flag or for their chief, needs some definite object on which to rest. The multitude of nameless combatants do not strike the imagination. They do not stand out, and are not realised, as distinct and living figures conspicuous to the view. Hence it is that the chief, as the most prominent, becomes the representative warrior; the martyr's aureole descends upon his brow, and thus by a confusion that seems the very irony of fate, the enthusiasm evoked by the self-sacrifice of thousands sheds a sacred glow around the very man whose prodigious egotism had rendered that sacrifice necessary.
Another form of moral paradox is derived from the fact that positive religions may override our moral perceptions in such a manner, that we may consciously admit a moral contradiction. In this respect there is a strict parallelism between our intellectual and our moral faculties. It is at present the professed belief of at least three-fourths of the Christian Church, and was for some centuries the firm belief of the entire Church, that on a certain night the Founder of the Christian faith, being seated at a supper table, held His own body in His own hand, broke that body, distributed it to His disciples, who proceeded to eat it, the same body remaining at the same moment seated intact at the table, and soon afterwards proceeding to the garden of Gethsemane. The fact of such a doctrine being believed, does not imply that the faculties of those who hold it are of such a nature that they perceive no contradiction or natural absurdity in these statements. The well-known argument derived from the obscurity of the metaphysical notion of substance is intended only in some slight degree to soften the difficulty. The contradiction is clearly perceived, but it is accepted by faith as part of the teaching of the Church.
What transubstantiation is in the order of reason the Augustinian doctrine of the damnation of unbaptised infants, and the Calvinistic doctrine of reprobation, are in the order of morals. Of these doctrines it is not too much to say, that in the form in which they have often been stated, they surpass in atrocity any tenets that have ever been admitted into any pagan creed, and would, if they formed an essential part of Christianity, amply justify the term “pernicious superstition,” which Tacitus applied to the faith. That a little child who lives but a few moments after birth and dies before it has been sprinkled with the sacred water is in such a sense responsible for its ancestors having 6,000 years before eaten some forbidden fruit that it may with perfect justice be resuscitated and cast into an abyss of eternal fire in expiation of this ancestral crime, that an all-righteous and all-merciful Creator in the full exercise of those attributes deliberately calls into existence sentient beings whom He has from eternity irrevocably destined to endless, unspeakable, unmitigated torture, are propositions which are at once so extravagantly absurd and so ineffably atrocious that their adoption might well lead men to doubt the universality of moral perceptions. Such teaching is in fact simply dæmonism, and dæmonism in its most extreme form. It attributes to the Creator acts of injustice and of barbarity, which it would be absolutely impossible for the imagination to surpass, acts before which the most monstrous excesses of human cruelty dwindle into insignificance, acts which are in fact considerably worse than any that theologians have attributed to the devil. If there were men who while vividly realising the nature of these acts naturally turned to them as the exhibitions of perfect goodness, all systems of ethics founded upon innate moral perceptions would be false. But happily this is not so. Those who embrace these doctrines do so only because they believe that some inspired Church or writer has taught them, and because they are still in that stage in which men consider it more irreligious to question the infallibility of an apostle than to disfigure by any conceivable imputation the character of the Deity. They accordingly esteem it a matter of duty, and a commendable exercise of humility, to stifle the moral feelings of their nature, and they at last succeed in persuading themselves that their Divinity would be extremely offended if they hesitated to ascribe to him the attributes of a fiend. But their moral feelings, though not unimpaired by such conceptions, are not on ordinary subjects generically different from those of their neighbours. With an amiable inconsistency they can even find something to revolt them in the lives of a Caligula or a Nero. Their theological estimate of justice and mercy is isolated. Their doctrine is accepted as a kind of moral miracle, and as is customary with a certain school of theologians, when they enunciate a proposition which is palpably self-contradictory they call it a mystery and an occasion for faith.
In this instance a distinct moral contradiction is consciously admitted. In the case of persecution, a strictly moral and logical inference is drawn from a very immoral proposition which is accepted as part of a system of dogmatic theology. The two elements that should be considered in punishing a criminal are the heinousness of his guilt and the injury he inflicts. When the greatest guilt and the greatest injury are combined, the greatest punishment naturally follows. No one would argue against the existence of a moral faculty, on the ground that men put murderers to death. When therefore theologians believed that a man was intensely guilty who held certain opinions, and that he was causing the damnation of his fellows if he propagated them, there was no moral difficulty in concluding that the heretic should be put to death. Selfish considerations may have directed persecution against heresy rather than against vice, but the Catholic doctrines of the guilt of error, and of the infallibility of the Church, were amply sufficient to justify it.
It appears then that a dogmatic system which is accepted on rational or other grounds, and supported by prospects of rewards and punishments, may teach a code of ethics differing from that of conscience; and that in this case the voice of conscience may be either disregarded or stifled. It is however also true, that it may be perverted. When, for example, theologians during a long period have inculcated habits of credulity, rather than habits of enquiry; when they have persuaded men that it is better to cherish prejudice than to analyse it; better to stifle every doubt of what they have been taught than honestly to investigate its value, they will at last succeed in forming habits of mind that will instinctively and habitually recoil from all impartiality and intellectual honesty. If men continually violate a duty they may at last cease to feel its obligation. But this, though it forms a great difficulty in ethical enquiries, is no argument against the reality of moral perceptions, for it is simply a law to which all our powers are subject. A bad intellectual education will produce not only erroneous or imperfect information but also a false ply or habit of judgment. A bad æsthetical education will produce false canons of taste. Systematic abuse will pervert and vitiate even some of our physical perceptions. In each case the experience of many minds under many conditions must be appealed to, to determine the standard of right and wrong, and long and difficult discipline is required to restore the diseased organ to sanity. We may decide particular moral questions by reasoning, but our reasoning is an appeal to certain moral principles which are revealed to us by intuition.
The principal difficulty I imagine which most men have in admitting that we possess certain natural moral perceptions arises from the supposition that it implies the existence of some mysterious agent like the dæmon of Socrates, which gives us specific and infallible information in particular cases. But this I conceive to be a complete mistake. All that is necessarily meant by the adherents of this school is comprised in two propositions. The first is that our will is not governed exclusively by the law of pleasure and pain, but also by the law of duty, which we feel to be distinct from the former, and to carry with it the sense of obligation. The second is that the basis of our conception of duty is an intuitive perception that among the various feelings, tendencies, and impulses that constitute our emotional being, there are some which are essentially good, and ought to be encouraged, and some which are essentially bad, and ought to be repressed. They contend that it is a psychological fact that we are intuitively conscious that our benevolent affections are superior to our malevolent ones, truth to falsehood, justice to injustice, gratitude to ingratitude, chastity to sensuality, and that in all ages and countries the path of virtue has been towards the higher and not towards the lower feelings. It may be that the sense of duty is so weak as to be scarcely perceptible, and then the lower part of our nature will be supreme. It may happen that certain conditions of society lead men to direct their anxiety for moral improvement altogether in one or two channels, as was the case in ancient Greece, where civic and intellectual virtues were very highly cultivated, and the virtue of chastity was almost neglected. It may happen that different parts of our higher nature in a measure conflict, as when a very strong sense of justice checks our benevolent feelings. Dogmatic systems may enjoin men to propitiate certain unseen beings by acts which are not in accordance with the moral law. Special circumstances may influence, and the intermingling of many different motives may obscure and complicate, the moral evolution; but above all these one great truth appears. No one who desires to become holier and better imagines that he does so by becoming more malevolent, or more untruthful, or more unchaste. Every one who desires to attain perfection in these departments of feeling is impelled towards benevolence, towards veracity, towards chastity.114
Now it is manifest that according to this theory the moral unity to be expected in different ages is not a unity of standard, or of acts, but a unity of tendency. Men come into the world with their benevolent affections very inferior in power to their selfish ones, and the function of morals is to invert this order. The extinction of all selfish feeling is impossible for an individual, and if it were general, it would result in the dissolution of society. The question of morals must always be a question of proportion or of degree. At one time the benevolent affections embrace merely the family, soon the circle expanding includes first a class, then a nation, then a coalition of nations, then all humanity, and finally, its influence is felt in the dealings of man with the animal world. In each of these stages a standard is formed, different from that of the preceding stage, but in each case the same tendency is recognised as virtue.
We have in this fact a simple, and as it appears to me a conclusive, answer to the overwhelming majority of the objections that are continually and confidently urged against the intuitive school. That some savages kill their old parents, that infanticide has been practised without compunction by even civilised nations, that the best Romans saw nothing wrong in the gladiatorial shows, that political or revengeful assassinations have been for centuries admitted, that slavery has been sometimes honoured and sometimes condemned, are unquestionable proofs that the same act may be regarded in one age as innocent, and in another as criminal. Now it is undoubtedly true that in many cases an historical examination will reveal special circumstances, explaining or palliating the apparent anomaly. It has been often shown that the gladiatorial shows were originally a form of human sacrifice adopted through religious motives; that the rude nomadic life of savages rendering impossible the preservation of aged and helpless members of the tribe, the murder of parents was regarded as an act of mercy both by the murderer and the victim; that before an effective administration of justice was organised, private vengeance was the sole preservative against crime,115 and political assassination against usurpation; that the insensibility of some savages to the criminality of theft arises from the fact that they were accustomed to have all things in common; that the Spartan law, legalising theft, arose partly from a desire to foster military dexterity among the people, but chiefly from a desire to discourage wealth; that slavery was introduced through motives of mercy, to prevent conquerors from killing their prisoners.116 All this is true, but there is another and a more general answer. It is not to be expected, and it is not maintained, that men in all ages should have agreed about the application of their moral principles. All that is contended for is that these principles are themselves the same. Some of what appear to us monstrous acts of cruelty, were dictated by that very feeling of humanity, the universal perception of the merit of which they are cited to disprove,117 and even when this is not the case, all that can be inferred is, that the standard of humanity was very low. But still humanity was recognised as a virtue, and cruelty as a vice.
At this point, I may observe how completely fallacious is the assertion that a progressive morality is impossible upon the supposition of an original moral faculty.118 To such statements there are two very simple answers. In the first place, although the intuitive moralist asserts that certain qualities are necessarily virtuous, he fully admits that the degree in which they are acted upon, or in other words, the standard of duty, may become progressively higher. In the next place, although he refuses to resolve all virtue into utility, he admits as fully as his opponents, that benevolence, or the promotion of the happiness of man, is a virtue, and that therefore discoveries which exhibit more clearly the true interests of our kind, may throw new light upon the nature of our duty.
The considerations I have urged with reference to humanity, apply with equal force to the various relations of the sexes. When the passions of men are altogether unrestrained, community of wives and all eccentric forms of sensuality will be admitted. When men seek to improve their nature in this respect, their object will be to abridge and confine the empire of sensuality. But to this process of improvement there are obvious limits. In the first place the continuance of the species is only possible by a sensual act. In the next place the strength of this passion and the weakness of humanity are so great, that the moralist must take into account the fact that in all societies, and especially in those in which free scope had long been given to the passions, a large amount of indulgence will arise which is not due to a simple desire of propagating the species. If then incest is prohibited, and community of wives replaced by ordinary polygamy, a moral improvement will have been effected, and a standard of virtue formed. But this standard soon becomes the starting-point of new progress. If we examine the Jewish law, we find the legislator prohibiting adultery, regulating the degrees of marriage, but at the same time authorising polygamy, though with a caution against the excessive multiplication of wives. In Greece monogamy, though not without exceptions, had been enforced, but a concurrence of unfavourable influences prevented any high standard being attained among the men, and in their case almost every form of indulgence beyond the limits of marriage was permitted. In Rome the standard was far higher. Monogamy was firmly established. The ideal of female morality was placed as high as among Christian nations. Among men, however, while unnatural love and adultery were regarded as wrong, simple unchastity before marriage was scarcely considered a fault. In Catholicism marriage is regarded in a twofold light, as a means for the propagation of the species, and as a concession to the weakness of humanity, and all other sensual enjoyment is stringently prohibited.
In these cases there is a great difference between the degrees of earnestness with which men exert themselves in the repression of their passions, and in the amount of indulgence which is conceded to their lower nature;119 but there is no difference in the direction of the virtuous impulse. While, too, in the case of adultery, and in the production of children, questions of interest and utility do undoubtedly intervene, we are conscious that the general progress turns upon a totally different order of ideas. The feeling of all men and the language of all nations, the sentiment which though often weakened is never wholly effaced, that this appetite, even in its most legitimate gratification, is a thing to be veiled and withdrawn from sight, all that is known under the names of decency and indecency, concur in proving that we have an innate, intuitive, instinctive perception that there is something degrading in the sensual part of our nature, something to which a feeling of shame is naturally attached, something that jars with our conception of perfect purity, something we could not with any propriety ascribe to an all-holy being. It may be questioned whether anyone was ever altogether destitute of this perception, and nothing but the most inveterate passion for system could induce men to resolve it into a mere calculation of interests. It is this feeling or instinct which lies at the root of the whole movement I have described, and it is this too that produced that sense of the sanctity of perfect continence which the Catholic church has so warmly encouraged, but which may be traced through the most distant ages, and the most various creeds. We find it among the Nazarenes and Essenes of Judæa, among the priests of Egypt and India, in the monasteries of Tartary, in the histories of miraculous virgins that are so numerous in the mythologies of Asia. Such, for example, was the Chinese legend that tells how when there was but one man with one woman upon earth, the woman refused to sacrifice her virginity even in order to people the globe, and the gods honouring her purity granted that she should conceive beneath the gaze of her lover's eyes, and a virgin-mother became the parent of humanity.120 In the midst of the sensuality of ancient Greece, chastity was the pre-eminent attribute of sanctity ascribed to Athene and Artemis. “Chaste daughter of Zeus,” prayed the suppliants in Æschylus, “thou whose calm eye is never troubled, look down upon us! Virgin, defend the virgins.” The Parthenon, or virgin's temple, was the noblest religious edifice of Athens. Celibacy was an essential condition in a few of the orders of priests, and in several orders of priestesses. Plato based his moral system upon the distinction between the bodily or sensual, and the spiritual or rational part of our nature, the first being the sign of our degradation, and the second of our dignity. The whole school of Pythagoras made chastity one of its leading virtues, and even laboured for the creation of a monastic system. The conception of the celestial Aphrodite, the uniter of souls, unsullied by the taint of matter, lingered side by side with that of the earthly Aphrodite or patroness of lust, and if there was a time when the sculptors sought to pander to the excesses of passion there was another in which all their art was displayed in refining and idealising it. Strabo mentions the existence in Thrace of societies of men aspiring to perfection by celibacy and austere lives. Plutarch applauds certain philosophers who vowed to abstain for a year from wine and women in order “to honour God by their continence.”121 In Rome the religious reverence was concentrated more especially upon married life. The great prominence accorded to the Penates was the religious sanction of domesticity. So too, at first, was the worship so popular among the Roman women of the Bona Dea—the ideal wife who according to the legend had, when on earth, never looked in the face or known the name of any man but her husband.122 “For altar and hearth” was the rallying cry of the Roman soldier. But above all this we find the traces of a higher ideal. We find it in the intense sanctity attributed to the vestal virgins whose continence was guarded by such fearful penalties, and supposed to be so closely linked with the prosperity of the state, whose prayer was believed to possess a miraculous power, and who were permitted to drive through the streets of Rome at a time when that privilege was refused even to the Empress.123 We find it in the legend of Claudia, who, when the ship bearing the image of the mother of the gods had been stranded in the Tiber, attached her girdle to its prow, and vindicated her challenged chastity by drawing with her virgin hand, the ponderous mass which strong men had sought in vain to move. We find it in the prophetic gift so often attributed to virgins,124 in the law which sheltered them from the degradation of an execution,125 in the language of Statius, who described marriage itself as a fault.126 In Christianity one great source of the attraction of the faith has been the ascription of virginity to its female ideal. The Catholic monastic system has been so constructed as to draw many thousands from the sphere of active duty; its irrevocable vows have doubtless led to much suffering and not a little crime; its opposition to the normal development of our mingled nature has often resulted in grave aberrations of the imagination, and it has placed its ban upon domestic affections and sympathies which have a very high moral value; but in its central conception that the purely animal side of our being is a low and a degraded side, it reflects, I believe, with perfect fidelity the feelings of our nature.127
To these considerations some others of a different nature may be added. It is not true that some ancient nations regarded polygamy as good in the same sense as others regarded chastity. There is a great difference between deeming a state permissible and proposing it as a condition of sanctity. If Mohammedans people paradise with images of sensuality, it is not because these form their ideal of holiness. It is because they regard earth as the sphere of virtue, heaven as that of simple enjoyment. If some pagan nations deified sensuality, this was simply because the deification of the forces of nature, of which the prolific energy is one of the most conspicuous, is among the earliest forms of religion, and long precedes the identification of the Deity with a moral ideal.128 If there have been nations who attached a certain stigma to virginity, this has not been because they esteemed sensuality intrinsically holier than chastity; but because a scanty, warlike people whose position in the world depends chiefly on the number of its warriors, will naturally make it its main object to encourage population. This was especially the case with the ancient Jews, who always regarded extreme populousness as indissolubly connected with national prosperity, whose religion was essentially patriotic, and among whom the possibility of becoming an ancestor of the Messiah had imparted a peculiar dignity to childbirth. Yet even among the Jews the Essenes regarded virginity as the ideal of sanctity.
The reader will now be in a position to perceive the utter futility of the objections which from the time of Locke have been continually brought against the theory of natural moral perceptions, upon the ground that some actions which were admitted as lawful in one age, have been regarded as immoral in another. All these become absolutely worthless when it is perceived that in every age virtue has consisted in the cultivation of the same feelings, though the standards of excellence attained have been different. The terms higher and lower, nobler or less noble, purer or less pure, represent moral facts with much greater fidelity than the terms right or wrong, or virtue or vice. There is a certain sense in which moral distinctions are absolute and immutable. There is another sense in which they are altogether relative and transient. There are some acts which are so manifestly and grossly opposed to our moral feelings, that they are regarded as wrong in the very earliest stages of the cultivation of these feelings. There are distinctions, such as that between truth and falsehood, which from their nature assume at once a sharpness of definition that separates them from mere virtues of degree, though even in these cases there are wide variations in the amount of scrupulosity that is in different periods required. But apart from positive commands, the sole external rule enabling men to designate acts, not simply as better or worse, but as positively right or wrong, is, I conceive, the standard of society; not an arbitrary standard like that which Mandeville imagined, but the level which society has attained in the cultivation of what our moral faculty tells us is the higher or virtuous part of our nature. He who falls below this is obstructing the tendency which is the essence of virtue. He who merely attains this, may not be justified in his own conscience, or in other words, by the standard of his own moral development, but as far as any external rule is concerned, he has done his duty. He who rises above this has entered into the region of things which it is virtuous to do, but not vicious to neglect—a region known among Catholic theologians by the name of “counsels of perfection.” No discussions, I conceive, can be more idle than whether slavery, or the slaughter of prisoners in war, or gladiatorial shows, or polygamy, are essentially wrong. They may be wrong now—they were not so once—and when an ancient countenanced by his example one or other of these, he was not committing a crime. The unchangeable proposition for which we contend is this—that benevolence is always a virtuous disposition—that the sensual part of our nature is always the lower part.
At this point, however, a very difficult problem naturally arises. Admitting that our moral nature is superior to our intellectual or physical nature, admitting, too, that by the constitution of our being we perceive ourselves to be under an obligation to develope our nature to its perfection, establishing the supreme ascendency of moral motives, the question still remains whether the disparity between the different parts of our being is such that no material or intellectual advantage, however great, may be rightly purchased by any sacrifice of our moral nature, however small. This is the great question of casuistry, the question which divines express by asking whether the end ever justifies the means; and on this subject there exists among theologians a doctrine which is absolutely unrealised, which no one ever dreams of applying to actual life, but of which it may be truly said that though propounded with the best intentions, it would, if acted upon, be utterly incompatible with the very rudiments of civilisation. It is said that an undoubted sin, even the most trivial, is a thing in its essence and in its consequences so unspeakably dreadful, that no conceivable material or intellectual advantage can counterbalance it; that rather than it should be committed, it would be better that any amount of calamity which did not bring with it sin should be endured, even that the whole human race should perish in agonies.129 If this be the case, it is manifest that the supreme object of humanity should be sinlessness, and it is equally manifest that the means to this end is the absolute suppression of the desires. To expand the circle of wants is necessarily to multiply temptations, and therefore to increase the number of sins. It may indeed elevate the moral standard, for a torpid sinlessness is not a high moral condition; but if every sin be what these theologians assert, if it be a thing deserving eternal agony, and so inconceivably frightful that the ruin of a world is a less evil than its commission, even moral advantages are utterly incommensurate with it. No heightening of the moral tone, no depth or ecstasy of devotion, can for a moment be placed in the balance. The consequences of this doctrine, if applied to actual life, would be so extravagant, that their simple statement is a refutation. A sovereign, when calculating the consequences of a war, should reflect that a single sin occasioned by that war, a single blasphemy of a wounded soldier, the robbery of a single hencoop, the violation of the purity of a single woman, is a greater calamity than the ruin of the entire commerce of his nation, the loss of her most precious provinces, the destruction of all her power. He must believe that the evil of the increase of unchastity, which invariably results from the formation of an army, is an immeasurably greater calamity than any material or political disasters that army can possibly avert. He must believe that the most fearful plague or famine that desolates his land should be regarded as a matter of rejoicing, if it has but the feeblest and most transient influence in repressing vice. He must believe that if the agglomeration of his people in great cities adds but one to the number of their sins, no possible intellectual or material advantages can prevent the construction of cities being a fearful calamity. According to this principle, every elaboration of life, every amusement that brings multitudes together, almost every art, every accession of wealth that awakens or stimulates desires, is an evil, for all these become the sources of some sins, and their advantages are for the most part purely terrestrial. The entire structure of civilisation is founded upon the belief that it is a good thing to cultivate intellectual and material capacities, even at the cost of certain moral evils which we are often able accurately to foresee.130 The time may come when the man who lays the foundation-stone of a manufacture will be able to predict with assurance in what proportion the drunkenness and the unchastity of his city will be increased by his enterprise. Yet he will still pursue that enterprise, and mankind will pronounce it to be good.
The theological doctrine on the subject, considered in its full stringency, though professed by many, is, as I have said, realised and consistently acted on by no one; but the practical judgments of mankind concerning the extent of the superiority of moral over all other interests vary greatly, and this variation supplies one of the most serious objections to intuitive moralists. The nearest practical approach to the theological estimate of a sin may be found in the ranks of the ascetics. Their whole system rests upon the belief that it is a thing so transcendently dreadful as to bear no proportion or appreciable relation to any earthly interests. Starting from this belief, the ascetic makes it the exclusive object of his life to avoid sinning. He accordingly abstains from all the active business of society, relinquishes all worldly aims and ambitions, dulls by continued discipline his natural desires, and endeavours to pass a life of complete absorption in religious exercises. And in all this his conduct is reasonable and consistent. The natural course of every man who adopts this estimate of the enormity of sin is at every cost to avoid all external influences that can prove temptations, and to attenuate as far as possible his own appetites and emotions. It is in this respect that the exaggerations of theologians paralyse our moral being. For the diminution of sins, however important, is but one part of moral progress. Whenever it is forced into a disproportionate prominence, we find tame, languid, and mutilated natures, destitute of all fire and energy, and this tendency has been still further aggravated by the extreme prominence usually given to the virtue of gentleness, which may indeed be attained by men of strong natures and vehement emotions, but is evidently more congenial to a somewhat feeble and passionless character.
Ascetic practices are manifestly and rapidly disappearing, and their decline is a striking proof of the evanescence of the moral notions of which they were the expression, but in many existing questions relating to the same matter, we find perplexing diversity of judgment. We find it in the contrast between the system of education usually adopted by the Catholic priesthood, which has for its pre-eminent object to prevent sins, and for its means a constant and minute supervision, and the English system of public schools, which is certainly not the most fitted to guard against the possibility of sin, or to foster any very delicate scrupulosity of feeling; but is intended, and popularly supposed, to secure the healthy expansion of every variety of capacity. We find it in the widely different attitudes which good men in different periods have adopted towards religious opinions they believe to be false; some, like the reformers, refusing to participate in any superstitious service, or to withhold on any occasion, or at any cost, their protest against what they regarded as a lie; others, like most ancient, and some modern philosophers and politicians, combining the most absolute personal incredulity with an assiduous observance of superstitious rites, and strongly censuring those who disturbed delusions which are useful or consolatory to the people; while a third class silently, but without protest, withdraw themselves from the observances, and desire that their opinions should have a free expression in literature, but at the same time discourage all proselytising efforts to force them rudely on unprepared minds. We find it in the frequent conflicts between the political economist and the Catholic priest on the subject of early marriages, the former opposing them on the ground that it is an essential condition of material well-being that the standard of comfort should not be depressed, the latter advocating them on the ground that the postponement of marriages, through prudential motives, by any large body of men, is the fertile mother of sin. We find it most conspicuously in the marked diversities of tolerance manifested in different communities towards amusements which may in themselves be perfectly innocent, but which prove the sources or the occasions of vice. The Scotch Puritans probably represent one extreme, the Parisian society of the empire the other, while the position of average Englishmen is perhaps equidistant between them. Yet this difference, great as it is, is a difference not of principle, but of degree. No Puritan seriously desires to suppress every clan-gathering, every highland game which may have occasioned an isolated fit of drunkenness, though he may be unable to show that it has prevented any sin that would otherwise have been committed. No Frenchman will question that there is a certain amount of demoralisation which should not be tolerated, however great the enjoyment that accompanies it. Yet the one dwells almost exclusively upon the moral, the other upon the attractive, nature of a spectacle. Between these there are numerous gradations, which are shown in frequent disputes about the merits and demerits of the racecourse, the ball, the theatre, and the concert. Where then, it may be asked, is the line to be drawn? By what rule can the point be determined at which an amusement becomes vitiated by the evil of its consequences?
To these questions the intuitive moralist is obliged to answer, that such a line cannot be drawn, that such a rule does not exist. The colours of our moral nature are rarely separated by the sharp lines of our vocabulary. They fade and blend into one another so imperceptibly, that it is impossible to mark a precise point of transition. The end of man is the full development of his being in that symmetry and proportion which nature has assigned it, and such a development implies that the supreme, the predominant motive of his life, should be moral. If in any society or individual this ascendency does not exist, that society or that individual is in a diseased and abnormal condition. But the superiority of the moral part of our nature, though unquestionable, is indefinite not infinite, and the prevailing standard is not at all times the same. The moralist can only lay down general principles. Individual feeling or the general sentiment of society must draw the application.
The vagueness that on such questions confessedly hangs over the intuitive theory, has always been insisted upon by members of the opposite school, who 'in the greatest happiness principle' claim to possess a definite formulary, enabling them to draw boldly the frontier line between the lawful and the illicit, and to remove moral disputes from the domain of feeling to that of demonstration. But this claim, which forms the great attraction of the utilitarian school, is, if I mistake not, one of the grossest of impostures. We compare with accuracy and confidence the value of the most various material commodities, for we mean by this term, exchangeable value, and we have a common measure of exchange. But we seek in vain for such a measure enabling us to compare different kinds of utility or happiness. Thus, to take a very familiar example, the question may be proposed, whether excursion trains from a country district to a seaport town produce more good than evil, whether a man governed by moral principles should encourage or oppose them. They give innocent and healthy enjoyment to many thousands, they enlarge in some degree the range of their ideas, they can hardly be said to prevent any sin that would otherwise have been committed, they give rise to many cases of drunkenness, each of which, according to the theological doctrine we have reviewed, should be deemed a more dreadful calamity than the earthquake of Lisbon, or a visitation of the cholera, but which have not usually any lasting terrestrial effects; they also often produce a measure, and sometimes no small measure, of more serious vice, and it is probable that hundreds of women may trace their first fall to the excursion train. We have here a number of advantages and disadvantages, the first being intellectual and physical, and the second moral. Nearly all moralists would acknowledge that a few instances of immorality would not prevent the excursion train being, on the whole, a good thing. All would acknowledge that very numerous instances would more than counterbalance its advantages. The intuitive moralist confesses that he is unable to draw a precise line, showing where the moral evils outweigh the physical benefits. In what possible respect the introduction of Benthamite formularies improves the matter, I am unable to understand. No utilitarian would reduce the question to one of simple majority, or would have the cynicism to balance the ruin of one woman by the day's enjoyment of another. The impossibility of drawing, in such cases, a distinct line of division, is no argument against the intuitive moralist, for that impossibility is shared to the full extent by his rival.
There are, as we have seen, two kinds of interest with which utilitarian moralists are concerned—the private interest which they believe to be the ultimate motive, and the public interest which they believe to be the end, of all virtue. With reference to the first, the intuitive moralist denies that a selfish act can be a virtuous or meritorious one. If a man when about to commit a theft, became suddenly conscious of the presence of a policeman, and through fear of arrest and punishment were to abstain from the act he would otherwise have committed, this abstinence would not appear in the eyes of mankind to possess any moral value; and if he were determined partly by conscientious motives, and partly by fear, the presence of the latter element would, in proportion to its strength, detract from his merit. But although selfish considerations are distinctly opposed to virtuous ones, it would be a mistake to imagine they can never ultimately have a purely moral influence. In the first place, a well-ordered system of threats and punishments marks out the path of virtue with a distinctness of definition it could scarcely have otherwise attained. In the next place, it often happens that when the mind is swayed by a conflict of motives, the expectation of reward or punishment will so reinforce or support the virtuous motives, as to secure their victory; and, as every triumph of these motives increases their strength and weakens the opposing principles, a step will thus have been made towards moral perfection, which will render more probable the future triumph of unassisted virtue.
With reference to the interests of society, there are two distinct assertions to be made. The first is, that although the pursuit of the welfare of others is undoubtedly one form of virtue, it does not include all virtue, or, in other words, that there are forms of virtue which, even if beneficial to mankind, do not become virtuous on that account, but have an intrinsic excellence which is not proportioned to or dependent on their utility. The second is, that there may occasionally arise considerations of extreme and overwhelming utility that may justify a sacrifice of these virtues. This sacrifice may be made in various ways—as, when a man undertakes an enterprise which is in itself perfectly innocent, but which in addition to its great material advantages will, as he well knows, produce a certain measure of crime; or when, abstaining from a protest, he tacitly countenances beliefs which he considers untrue, because he regards them as transcendently useful; or again, when, for the benefit of others, and under circumstances of great urgency, he utters a direct falsehood, as, for example, when by such means alone he can save the life of an innocent man.131 But the fact, that in these cases considerations of extreme utility are suffered to override considerations of morality, is in no degree inconsistent with the facts, that the latter differ in kind from the former, that they are of a higher nature, and that they may supply adequate and legitimate motives of action not only distinct from, but even in opposition to utility. Gold and silver are different metals. Gold is more valuable than silver; yet a very small quantity of gold may be advantageously exchanged for a very large quantity of silver.
The last class of objections to the theory of natural moral perceptions which it is necessary for me to notice, arises from a very mischievous equivocation in the word natural.132 The term natural man is sometimes regarded as synonymous with man in his primitive or barbarous condition, and sometimes as expressing all in a civilised man that is due to nature as distinguished from artificial habits or acquirements. This equivocation is especially dangerous, because it implies one of the most extravagant excesses to which the sensational philosophy could be pushed—the notion that the difference between a savage and a civilised man is simply a difference of acquisition, and not at all a difference of development. In accordance with this notion, those who deny original moral distinctions have ransacked the accounts of travellers for examples of savages who appeared destitute of moral sentiments, and have adduced them as conclusive evidence of their position. Now it is, I think, abundantly evident that these narratives are usually exceedingly untrustworthy.133 They have been in most cases collected by uncritical and unphilosophical travellers, who knew little of the language and still less of the inner life of the people they described, whose means of information were acquired in simply traversing the country, who were more struck by moral paradox, than by unostentatious virtue, who were proverbially addicted to embellishing and exaggerating the singularities they witnessed, and who very rarely investigated their origin. It should not be forgotten that the French moralists of the last century, who insisted most strongly on this species of evidence, were also the dupes of one of the most curious delusions in the whole compass of literary history. Those unflinching sceptics who claimed to be the true disciples of the apostle who believed nothing that he had not touched, and whose relentless criticism played with withering effect on all the holiest feelings of our nature, and on all the tenets of traditional creeds, had discovered one happy land where the ideal had ceased to be a dream. They could point to one people whose pure and rational morality, purged from all the clouds of bigotry and enthusiasm, shone with an almost dazzling splendour above the ignorance and superstition of Europe. Voltaire forgot to gibe, and Helvétius kindled into enthusiasm, when China and the Chinese rose before their minds, and to this semi-barbarous nation they habitually attributed maxims of conduct that neither Roman nor Christian virtue had ever realised.
But putting aside these considerations, and assuming the fidelity of the pictures of savage life upon which these writers rely, they fail to prove the point for which they are adduced. The moralists I am defending, assert that we possess a natural power of distinguishing between the higher and lower parts of our nature. But the eye of the mind, like the eye of the body, may be closed. Moral and rational facilities may be alike dormant, and they will certainly be so if men are wholly immersed in the gratification of their senses. Man is like a plant, which requires a favourable soil for the full expansion of its natural or innate powers.134 Yet those powers both rational and moral are there, and when quickened into action, each will discharge its appointed functions. If it could be proved that there are savages who are absolutely destitute of the progressive energy which distinguishes reason from instinct and of the moral aspiration which constitutes virtue, this would not prove that rational or moral faculties form no part of their nature. If it could be shown that there is a stage of barbarism in which man knows, feels and does nothing that might not be known, felt and done by an ape, this would not be sufficient to reduce him to the level of the brute. There would still be this broad distinction between them—the one possesses a capacity for development which the other does not possess. Under favourable circumstances the savage will become a reasoning, progressive, and moral man: under no circumstances can a similar transformation be effected in the ape. It may be as difficult to detect the oakleaf in the acorn as in the stone; yet the acorn may be converted into an oak: the stone will always continue to be a stone.135
The foregoing pages will, I trust, have exhibited with sufficient clearness the nature of the two great divisions of moral philosophy—the school which proceeds from the primitive truth that all men desire happiness, and endeavours out of this fact to evolve all ethical doctrines, and the school which traces our moral systems to an intuitive perception that certain parts of our nature are higher or better than others. It is obvious that this difference concerning the origin of our moral conceptions forms part of the very much wider metaphysical question, whether our ideas are derived exclusively from sensation or whether they spring in part from the mind itself. The latter theory in antiquity was chiefly represented by the Platonic doctrine of pre-existence, which rested on the conviction that the mind has the power of drawing from its own depths certain conceptions or ideas which cannot be explained by any post-natal experience, and must therefore, it was said, have been acquired in a previous existence. In the seventeenth century it took the form of a doctrine of innate ideas. But though this theory in the form in which it was professed by Lord Herbert of Cherbury and assailed by Locke has almost disappeared, the doctrine that we possess certain faculties which by their own expansion, and not by the reception of notions from without, are not only capable of, but must necessarily attain, certain ideas, as the bud must necessarily expand into its own specific flower, still occupies a distinguished place in the world of speculation, and its probability has been greatly strengthened by recent observations of the range and potency of instinct in animals. From some passages in his Essay, it appears that Locke himself had a confused perception of this distinction,136 which was by no means unknown to previous writers; and after the publication of the philosophy of Locke it was clearly exhibited by Shaftesbury and Leibnitz, and incidentally noticed by Berkeley long before Kant established his distinction between the form and the matter of our knowledge, between ideas which are received a priori and ideas which are received a posteriori. The existence or non-existence of this source of ideas forms the basis of the opposition between the inductive philosophy of England and the French philosophy of the eighteenth century on the one hand, and the German and Scotch philosophies, as well as the French eclecticism of the nineteenth century upon the other. The tendency of the first school is to restrict as far as possible the active powers of the human mind, and to aggrandise as far as possible the empire of external circumstances. The other school dwells especially on the instinctive side of our nature, and maintains the existence of certain intuitions of the reason, certain categories or original conceptions, which are presupposed in all our reasonings and cannot be resolved into sensations. The boast of the first school is that its searching analysis leaves no mental phenomenon unresolved, and its attraction is the extreme simplicity it can attain. The second school multiplies faculties or original principles, concentrates its attention mainly upon the nature of our understanding, and asserts very strongly the initiative force both of our will and of our intellect.
We find this connection between a philosophy based upon the senses, and a morality founded upon utility from the earliest times. Aristotle was distinguished among the ancients for the emphasis with which he dwelt upon the utility of virtue, and it was from the writings of Aristotle that the schoolmen derived the famous formulary which has become the motto of the school of Locke. Locke himself devoted especial research to the refutation of the doctrine of a natural moral sense, which he endeavoured to overthrow by a catalogue of immoral practices that exist among savages, and the hesitation he occasionally exhibited in his moral doctrine corresponds not unfaithfully to the obscurity thrown over his metaphysics by the admission of reflection as a source of ideas. If his opponent Leibnitz made pleasure the object of moral action, it was only that refined pleasure which is produced by the contemplation of the happiness of others. When, however, Condillac and his followers, removing reflection from the position Locke had assigned it, reduced the philosophy of sensation to its simplest expression, and when the Scotch and German writers elaborated the principles of the opposite school, the moral tendencies of both were indisputably manifested. Everywhere the philosophy of sensation was accompanied by the morals of interest, and the ideal philosophy, by an assertion of the existence of a moral faculty, and every influence that has affected the prevailing theory concerning the origin of our ideas, has exercised a corresponding influence upon the theories of ethics.
