ОглавлениеIt Does Not Give a Criterion for Concrete Acts.
Pleasure, as the end, fails also to throw light on the moral value of any specific acts. Its failure in this respect is, indeed, only the other side of that just spoken of. There is no organizing principle, no 'universal' on the basis of which various acts fall into a system or order. The moral life is left a series of shreds and patches, where each act is torn off, as to its moral value, from every other. Each act is right or wrong, according as it gives pleasure or pain, and independently of any whole of life. There is, indeed, no whole of moral life at all, but only a series of isolated, disconnected acts. Possession, passivity, mere feeling, by its very nature cannot unite—each feeling is itself and that is the end of it. It is action which reduces multiplicity to unity. We cannot say, in the hedonistic theory, that pleasure is the end, but pleasures.
Each act stands by itself—the only question is: What pleasure will it give? The settling of this question is the "hedonistic calculus." We must discover the intensity, duration, certainty, degree of nearness of the pleasure likely to arise from the given act, and also its purity, or likelihood of being accompanied by secondary pains and pleasures. Then we are to strike the balance between the respective sums on the pleasure and pain sides, and, according as this balance is one of pleasure or pain, the act is good or evil.
Bentham, Op. cit., p. 16, was the first to go into detail as to this method. He has also given certain memoriter verses stating "the points on which the whole fabric of morals and legislation may be seen to rest.
Intense, long, certain, speedy, fruitful, pure,
Such marks in pleasures and in pains endure,
Such pleasures seek, if private be thy end.
If it be public, wide let them extend.
Such pains avoid whichever be thy view,
If pains must come, let them extend to few."
This, however, in its reference to others, states the utilitarian as well as the hedonistic view.
Now, it must be remembered that, if pleasure is the end, there is no intrinsic connection between the motive of the act, and its result. It is not claimed that there is anything belonging intrinsically to the motive of the act which makes it result in pleasure or pain. To make such a claim would be to declare the moral quality of the act the criterion of the pleasure, instead of pleasure the criterion of the act. The pleasures are external to the act; they are irrelevant and accidental to its quality. There is no 'universal,' no intrinsic bond of connection between the act and its consequences. The consequence is a mere particular state of feeling, which, in this instance, the act has happened to bring about.
More concretely, this act of truth-telling has in this instance, brought about pleasure. Shall we call it right? Right in this instance, of course; but is it right generally? Is truth-telling, as such, right, or is it merely that this instance of it happens to be right? Evidently, on the hedonistic basis, we cannot get beyond the latter judgment. Prior to any act, there will be plenty of difficulties in telling whether it, as particular, is right or wrong. The consequences depend not merely on the result intended, but upon a multitude of circumstances outside of the foresight and control of the agent. And there can be only a precarious calculation of possibilities and probabilities—a method which would always favor laxity of conduct in all but the most conscientious of men, and which would throw the conscientious into uncertainty and perplexity in the degree of their conscientiousness.
"If once the pleas of instinct are to be abolished and replaced by a hedonistic arithmetic, the whole realm of animated nature has to be reckoned with in weaving the tissue of moral relations, and the problem becomes infinite and insoluble".—Martineau, Op. cit., Vol. II, p. 334.
But waive this; let the particular case be settled. There is still no law, no principle, indeed no presumption as to future conduct. The act is not right because it is truth-telling, but because, in this instance, circumstances were such as to throw a balance of pleasure in its favor. This establishes no certainty, no probability as to its next outcome. The result then will depend wholly upon circumstances existing then—circumstances which have no intrinsic relation to the act and which must change from time to time.
The hedonist would escape this abolition of all principle, or even rule, by falling back upon a number of cases—'past experience' it is called. We have found in a number of cases that a certain procedure has resulted in pleasure, and this result is sufficient to guide us in a vast number of cases which come up.
Says Mill (Op. cit., pp. 332-4): "During the whole past duration of the species, mankind have been learning by experience the tendencies of actions, on which experience all the prudence as well as all the morality of life are dependent.... Mankind must by this time have acquired positive belief as to the effects of some actions on their happiness; and the beliefs which have thus come down are the rules of morality for the multitude, and for the philosopher, until he has succeeded in finding better.... Nobody argues that the art of navigation is not founded on astronomy, because sailors cannot wait to calculate the 'Nautical Almanac'. Being rational creatures, they go to sea with it ready calculated; and all rational creatures go out upon the sea of life with their minds made up on the common questions of right and wrong, as well as on many of the far more difficult questions of wise and foolish."
That we do learn from experience the moral nature of actions is undoubted. The only question is: if hedonism were true, could we so learn? Suppose that I were convinced that the results of murder in the past had been generally, or even without exception (though this could not be proved), painful; as long as the act and the result in the way of feeling (pain or pleasure) are conceived as having no intrinsic connection, this would not prove that in the present instance murder will give a surplus of pain. I am not thinking of committing murder in general, but of murder under certain specific present circumstances. These circumstances may, and, to some extent, must vary from all previous instances of murder. How then can I reason from them to it? Or, rather, let me use the previous cases as much as I may, the moral quality of the act I am now to perform must still be judged not from them, but from the circumstances of the present case. To judge otherwise, is, on hedonistic principles, to be careless, perhaps criminally careless as to one's conduct. The more convinced a man is of the truth of hedonism and the more conscientious he is, the more he is bound not to be guided by previous circumstances, but to form his judgment anew concerning the new case. This result flows out of the very nature of the hedonistic ideal. Pleasure is not an activity, but simply a particular feeling, enduring only while it is felt. Moreover, there is in it no principle which connects it intrinsically with any kind of action. To suppose then that, because ninety-nine cases of murder have resulted in pain, the hundredth will, is on a par with reasoning that because ninety-nine days have been frosty, the hundredth will be. Each case, taken as particular, must be decided wholly by itself. There is no continuous moral life, and no system of conduct. There is only a succession of unlike acts.
Mill, in his examination of Whewell, (Diss. and Diss., Vol. III, pp. 158-59), tries to establish a general principle, if not a universal law, by arguing that, even in exceptional cases, the agent is bound to respect the rule, because to act otherwise would weaken the rule, and thus lead to its being disregarded in other cases, in which its observance results in pleasure. There are, he says, persons so wicked that their removal from the earth would undoubtedly increase the sum total of happiness. But if persons were to violate the general rule in these cases, it would tend to destroy the rule. "If it were thought allowable for any one to put to death at pleasure any human being whom he believes that the world would be well rid of,—nobody's life would be safe." That is to say, if every one were really to act upon and carry out the hedonistic principle, no rule of life would exist. This does very well as a reductio ad absurdum of hedonism, or as an argument against adopting hedonism, but it is difficult to see how Mill thought that it established a 'rule' on a hedonistic basis. Mill's argument comes to saying that if hedonism were uniformly acted upon, it would defeat itself—that is, pleasure would not result. Therefore, in order to get pleasure, we must not act upon the principle of hedonism at all, but follow a general rule. Otherwise put: hedonism gives no general rule, but we must have a general rule to make hedonism works and therefore there is a general rule! This begging of the question comes out even more plainly as Mill goes on: "If one person may break through the rule on his own judgment, the same liberty cannot be refused to others; and, since no one could rely on the rule's being observed, the rule would cease to exist." All of this is obviously true, but it amounts to saying: "We must have a rule, and this we would not have if we carried out the hedonistic principle in each case; therefore, we must not carry it out." A principle, that carried out destroys all rules which pretend to rest upon it, lays itself open to suspicion. Mill assumes the entire question in assuming that there is a rule. Grant this, and the necessity of not 'making exceptions,' that is, of not applying the hedonistic standard to each case, on its own merits, follows. But the argument which Mill needs to meet is that hedonism requires us to apply the standard to each case in itself, and that, therefore, there is no rule. Mill simply says—assume the rule, and it follows, etc.
