explication of this sort of signs. The instances I have given in this one, may give occasion to reflect on their use and force in language, and lead us into the contemplation of several actions of our minds in discoursing, which it has found a way to intimate to others by these particles; some whereof constantly, and others in certain constructions, have the sense of a whole sentence contained in them.

CHAP. VIII.

Of Abstract and Concrete Terms.

§. 1. THE ordinary words of language,

and our common use of them, would have given us light into the nature of our ideas, if they had been but considered with attention. The mind, as has been shown, has a power to abstract its ideas, and so they become essences, general essences, whereby the sorts of things are distinguished. Now each abstract idea being distinct, so that of any two the one can never be the other, the mind will, by its intuitive knowledge, perceive their difference; and therefore in propositions no two whole ideas can ever be affirmed one of another. This we see in the common use of language, which permits not any two abstract words, or naines of abstract ideas, to be affirmed one of another. For how near of kin soever they may seem to be, and how certain soever it is, that man is an animal, or rational, or white, yet every one at first hearing perceives the falsehood of these propositions; humanity is animality, or rationality, or whiteness: and this is as evident, as any of the most allowed maxims. All our affirmations then are only inconcrete, which is the affirming, not one abstract idea to be another, but one abstract idea to be joined to another; which abstract ideas, in substances, may be of any sort; in all the rest, are little else but of relations;

and in substances, the most frequent are of powers; v. g. a man is white," signifies, that the thing that has the essence of a man, has also in it the essence of whiteness, which is nothing but a power to produce the idea of whiteness in one, whose eyes can discover ordinary objects; or "a man is rational," signifies that the same thing that hath the essence of a man, hath also in it the essence of rationality, i. e. a power of reasoning. §. 2. This distinction of names shows us also the difference of our ideas: for if we observe them, we shall find that our simple ideas have all abstract, as well as concrete names; the one whereof is (to speak the language of grammarians) a substantive, the other an adjective; as whiteness, white, sweetness, sweet. The like also holds in our ideas of modes and relations; as justice, just; equality, equal; only with this difference, that some of the concrete names of relations, amongst men chiefly, are substantives; as paternitas, pater; whereof it were easy to render a reason. But as to our ideas of substances, we have very few or no abstract names at all. For though the schools have introduced animalitas, humanitas, corporietas, and some others; yet they hold no proportion with that infinite number of names of substances, to which they never were ridiculous enough to attempt the coining of abstract ones: and those few that the schools forged, and put into the mouths of their scholars, could never yet get admittance into common use, or obtain the licence of public approbation. Which seems to me at least to intimate the confession of all mankind, that they have no ideas of the real essences of substances, since they have not names for such ideas: which no doubt they would have had, had not their consciousness to themselves of their ignorance of them kept them from so idle an attempt. And therefore though they had ideas enough to distinguish gold from a stone, and metal from wood; yet they but timorously ventured on such terms, as aurietas and saxietas, metallietas and lignietas, or the like names, which should pretend to signify the real essences of those substances, whereof they knew they had no ideas. And indeed it

was only the doctrine of substantial forms, and the confidence of mistaken pretenders to a knowledge that they had not, which first coined, and then introduced animalitas, and humanitas, and the like; which yet went very little farther than their own schools, and could never get to be current amongst understanding men. Indeed, humanitas was a word familiar amongst the Romans, but in a far different sense, and stood not for the abstract essence of any substance; but was the abstracted name of a mode, and its concrete humanus, not homo.

CHA P. IX.

Of the Imperfection of Words.

[ocr errors]

§. 1. ROM what has been said in the foregoing chapters, it is easy to perceive what imperfection there is in lancommunicat- guage, and how the very nature of words ing our makes it almost unavoidable for many of thoughts. them to be doubtful and uncertain in their significations. To examine the perfection or imperfection of words, it is necessary first to consider their use and end for as they are more or less fitted to attain that, so they are more or less perfect. We have, in the former part of this discourse, often upon occasion men tioned a double use of words.

First, one for the recording of our own thoughts. Secondly, the other for the communicating of our thoughts to others.

Any words will serve for recording.

§. 2. As to the first of these, for the recording our own thoughts for the help of our own memories, whereby, as it were, we talk to ourselves, any words will serve the turn. For since sounds are voluntary and indifferent signs of any ideas, a man may use what words he pleases, 'to signify his own ideas to himself: and there will be no imperfection in them, if he constantly use the same

sign for the same idea; for then he cannot fail of having his meaning understood, wherein consists the right use and perfection of language.

.3. Secondly, as to communication of words, that too has a double use.

1. Civil.

II. Philosophical.

Communication by words civil

or philosophical.

First, by their civil use, I mean such a communication of thoughts and ideas by words, as may serve for the upholding common conversation and commerce, about the ordinary affairs and conveniencies of civil life, in the societies of men one amongst another.

Secondly, by the philosophical use of words, I mean such an use of them, as may serve to convey the precise notions of things, and to express, in general propositions, certain and undoubted truths, which the mind may rest upon, and be satisfied with, in its search after true knowledge. These two uses are very distinct; and a great deal less exactness will serve in the one than in the other, as we shall see in what follows.

The imperfection of

words is the

doubtfulness of their sig

nification.

§. 4. The chief end of language in communication being to be understood, words serve not well for that end, neither in civil nor philosophical discourse, when any word does not excite in the hearer the same idea which it stands for in the mind or the speaker. Now since sounds have no natural connexion with our ideas, but have all their signification from the arbitrary imposition of men, the doubtfulness and uncertainty of their signification, which is the imperfection we here are speaking of, has its cause more in the ideas they stand for, than in any incapacity there is in one sound more than in another, to signify any idea: for in that regard they are all equally perfect.

That then which makes doubtfulness and uncertainty in the signification of some more than other words, is the difference of ideas they stand for.

§. 5. Words having naturally no signification, the idea which each stands for must be learned and retained by those who would exchange thoughts, and hold intelligible B 4

discourse with others in any language. But this is hardest to be done, where,

First, the ideas they stand for are very complex, and made up of a great number of ideas put together.

Secondly, where the ideas they stand for have no certain connexion in nature; and so no settled standard, any where in nature existing, to rectify and adjust them by.

Thirdly, when the signification of the word is referred to a standard, which standard is not easy to be known.

Fourthly, where the signification of the word, and the real essence of the thing, are not exactly the same. These are difficulties that attend the signification of several words that are intelligible. Those which are not intelligible at all, such as names standing for any simple ideas, which another has not organs or faculties to attain; as the names of colours to a blind man, or sounds to a deaf man; need not here be mentioned.

In all these cases we shall find an imperfection in words, which I shall more at large explain, in their particular application to our several sorts of ideas for if we examine them, we shall find that the names of mixed modes are most liable to doubtfulness and imperfection, for the two first of these reasons; and the names of substances chiefly for the two latter.

§. 6. First the names of mixed modes are many of them liable to great uncertainty and obscurity in their signification.

The names of mixed modesdoubtful. First, because the I. Because of that great composition these ideas they complex ideas are often made up of. To stand for are make words serviceable to the end of comso complex. munication, it is necessary (as has been said) that they excite in the hearer exactly the same idea they stand for in the mind of the speaker. Without this, men fill one another's heads with noise and sounds; but convey not thereby their thoughts, and lay not before one another their ideas, which is the end of discourse and language. But when a word stands for a very complex idea that is compounded and decompounded, it is not easy for men to form and retain that idea so exactly,
