By our apprehension of propositions I mean our imposition of a sense on the terms of which they are composed. Now what do the terms of a proposition, the subject and predicate, stand for? Sometimes they stand for certain ideas existing in our own minds, and for nothing outside of them; sometimes for things simply external to us, brought home to us through the experiences and informations we have of them. All things in the exterior world are unit and individual, and are nothing else; but the mind not only contemplates those unit realities, as they exist, but has the gift, by an act of creation, of bringing before it abstractions and generalizations, which have no existence, no counterpart, out of it.

Now there are propositions, in which one or both of the terms are common nouns, as standing for what is abstract, general, and non-existing, such as “Man is an animal, some men are learned, an Apostle is a creation of Christianity, a line is length without breadth, to err is human, to forgive divine.” These I shall call notional propositions, and the apprehension with which we infer or assent to them, notional.

And there are other propositions, which are composed of singular nouns, and of which the terms stand for [pg 010] things external to us, unit and individual, as “Philip was the father of Alexander,” “the earth goes round the sun,” “the Apostles first preached to the Jews;” and these I shall call real propositions, and their apprehension real.

There are then two apprehensions or interpretations to which propositions may be subjected, notional and real.

Next I observe, that the same proposition may admit of both of these interpretations at once, having a notional sense as used by one man, and a real as used by another. Thus a schoolboy may perfectly apprehend, and construe with spirit, the poet's words, “Dum Capitolium scandet cum tacitâ Virgine Pontifex;” he has seen steep hills, flights of steps, and processions; he knows what enforced silence is; also he knows all about the Pontifex Maximus, and the Vestal Virgins; he has an abstract hold upon every word of the description, yet without the words therefore bringing before him at all the living image which they would light up in the mind of a contemporary of the poet, who had seen the fact described, or of a modern historian who had duly informed himself in the religious phenomena, and by meditation had realized the Roman ceremonial, of the age of Augustus. Again, “Dulce et decorum est pro patriâ mori,” is a mere common-place, a terse expression of abstractions in the mind of the poet himself, if Philippi is to be the index of his patriotism, whereas it would be the record of experiences, a sovereign dogma, a grand aspiration, inflaming the imagination, piercing the heart, of a Wallace or a Tell.

As the multitude of common nouns have originally been singular, it is not surprising that many of them should so remain still in the apprehension of particular individuals. In the proposition “Sugar is sweet,” the predicate is a common noun as used by those who have compared sugar in their thoughts with honey or glycerine; but it may be the only distinctively sweet thing in the experience of a child, and may be used by him as a noun singular. The first time that he tastes sugar, if his nurse says, “Sugar is sweet” in a notional sense, meaning by sugar, lump-sugar, powdered, brown, and candied, and by sweet, a specific flavour or scent which is found in many articles of food and many flowers, he may answer in a real sense, and in an individual proposition “Sugar is sweet,” meaning “this sugar is this sweet thing.”

Thirdly, in the same mind and at the same time, the same proposition may express both what is notional and what is real. When a lecturer in mechanics or chemistry shows to his class by experiment some physical fact, he and his hearers at once enunciate it as an individual thing before their eyes, and also as generalized by their minds into a law of nature. When Virgil says, “Varium et mutabile semper fœmina,” he both sets before his readers what he means to be a general truth, and at the same time applies it individually to the instance of Dido. He expresses at once a notion and a fact.

Of these two modes of apprehending propositions, notional and real, real is the stronger; I mean by stronger the more vivid and forcible. It is so to be accounted for the very reason that it is concerned with what is [pg 012] either real or taken for real; for intellectual ideas cannot compete in effectiveness with the experience of concrete facts. Various proverbs and maxims sanction me in so speaking, such as, “Facts are stubborn things,” “Experientia docet,” “Seeing is believing;” and the popular contrast between theory and practice, reason and sight, philosophy and faith. Not that real apprehension, as such, impels to action, any more than notional; but it excites and stimulates the affections and passions, by bringing facts home to them as motive causes. Thus it indirectly brings about what the apprehension of large principles, of general laws, or of moral obligations, never could effect.

Reverting to the two modes of holding propositions, conditional and unconditional, which was the subject of the former Section, that is, inferences and assents, I observe that inferences, which are conditional acts, are especially cognate to notional apprehension, and assents, which are unconditional, to real. This distinction, too, will come before us in the course of the following chapters.

And now I have stated the main subjects of which I propose to treat; viz., the distinctions in the use of propositions, which I have been drawing, and the questions which those distinctions involve.
