      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.

Chapter II. Assent Considered As Apprehensive.

       Table of Contents

      I have already said of an act of Assent, first, that it is in itself the absolute acceptance of a proposition without any condition; and next that, in order to its being made, it presupposes the condition, not only of some previous inference in favour of the proposition, but especially of some concomitant apprehension of its terms. I proceed to the latter of these two subjects; that is, of Assent considered as apprehensive, leaving the discussion of Assent as unconditional for a later place in this Essay.

      By apprehension of a proposition, I mean, as I have already said, the interpretation given to the terms of which it is composed. When we infer, we consider a proposition in relation to other propositions; when we assent to it, we consider it for its own sake and in its intrinsic sense. That sense must be in some degree known to us; else, we do but assert the proposition, we in no wise assent to it. Assent I have described to be a mental assertion; in its very nature then it is of the mind, and not of the lips. We can assert without assenting; assent is more than assertion just by this much, that it is accompanied by some apprehension of [pg 014] the matter asserted. This is plain; and the only question is, what measure of apprehension is sufficient.

      And the answer to this question is equally plain:—it is the predicate of the proposition which must be apprehended. In a proposition one term is predicated of another; the subject is referred to the predicate, and the predicate gives us information about the subject;—therefore to apprehend the proposition is to have that information, and to assent to it is to acquiesce in it as true. Therefore I apprehend a proposition, when I apprehend its predicate. The subject itself need not be apprehended per se in order to a genuine assent: for it is the very thing which the predicate has to elucidate, and therefore by its formal place in the proposition, so far as it is the subject, it is something unknown, something which the predicate makes known; but the predicate cannot make it known, unless it is known itself. Let the question be, “What is Trade?” here is a distinct profession of ignorance about “Trade;” and let the answer be, “Trade is the interchange of goods;”—trade then need not be known, as a condition of assent to the proposition, except so far as the account of it which is given in answer, “the interchange of goods,” makes it known; and that must be apprehended in order to make it known. The very drift of the proposition is to tell us something about the subject; but there is no reason why our knowledge of the subject, whatever it is, should go beyond what the predicate tells us about it. Further than this the subject need not be apprehended: as far as this it must; it will not be apprehended thus far, unless we apprehend the predicate.

      If a child asks, “What is Lucern?” and is answered, “Lucern is medicago sativa, of the class Diadelphia and order Decandria;” and henceforth says obediently, “Lucern is medicago sativa, &c.,” he makes no act of assent to the proposition which he enunciates, but speaks like a parrot. But, if he is told, “Lucern is food for cattle,” and is shown cows grazing in a meadow, then though he never saw lucern, and knows nothing at all about it, besides what he has learned from the predicate, he is in a position to make as genuine an assent to the proposition “Lucern is food for cattle,” on the word of his informant, as if he knew ever so much more about lucern. And as soon as he has got as far as this, he may go further. He now knows enough about lucern, to enable him to apprehend propositions
