notice of, but what have names; and those species, or rather their essences, being abstract complex ideas made arbitrarily by the mind; it is convenient, if not necessary, to know the names, before one endeavour to frame these complex ideas: unless a man will fill his head with a company of abstract complex ideas, which others having no names for, he has nothing to do with, but to lay by and forget again. I confess, that in the beginning of languages it was necessary to have the idea, before one gave it the name: and so it is still, where making a new complex idea, one also, by giving it a new name, makes a new word. But this concerns

not languages made, which have generally pretty well provided for ideas, which men have frequent occasion to have and communicate: and in such, I ask, whether it be not the ordinary method, that children learn the names of mixed modes, before they have their ideas? What one of a thousand ever frames the abstract ideas of glory and ambition, before he has heard the names of them? In simple ideas and substances I grant it is otherwise; which being such ideas as have a real existence and union in nature, the ideas and names are got one before the other, as it happens.

Reason of

16. What has been said here of mixed my being so modes is with very little difference applicalarge on this ble also to relations; which, since every subject. man himself may observe, I may spare myself the pains to enlarge on: especially, since what I have here said concerning words in this third book, will possibly be thought by some to be much more than what so slight a subject required. I allow it might be brought into a narrower compass: but I was willing to stay my reader on an argument that appears to me new, and a little out of the way, (I am sure it is one I thought not of when I began to write) that by searching it to the bottom, and turning it on every side, some part or other might meet with every one's thoughts, and give occasion to the most averse or negligent to reflect on a general miscarriage; which, though of great consequence, is little taken notice of. When it is considered what a pudder is made about

essences, and how much all sorts of knowledge, discourse, and conversation are pestered and disordered by the careless and confused use and application of words, it will perhaps be thought worth while thoroughly to lay it open. And I shall be pardoned if I have dwelt long on an argument which I think therefore needs to be inculcated; because the faults, men are usually guilty of in this kind, are not only the greatest hindrances of true knowledge, but are so well thought of as to pass for it. Men would often see what a small pittance of reason and truth, or possibly none at all, is mixed with those huffing opinions they are swelled with, if they would but look beyond fashionable sounds, and observe what ideas are, or are not comprehended under those words with which they are so armed at all points, and with which they so confidently lay about them. I shall imagine I have done some service to truth, peace, and learning, if, by any enlargement on this subject, I can make men reflect on their own use of language; and give them reason to suspect, that since it is frequent for others, it may also be possible for them to have sometimes very good and approved words in their mouths and writings, with very uncertain, little, or no signification. And therefore it is not unreasonable for them to be wary herein themselves, and not to be unwilling to have them examined by others. With this design therefore I shall go on with what I have farther to say con cerning this matter.

CHAP. VI.

Of the Names of Substances.

1. THE common names of substances, The common as well as other general terms, stand for names of subsorts; which is nothing else but the being stances stand made signs of such complex ideas, wherein for sorts.

several particular substances do, or might agree, by vir-
tue of which they are capable of being comprehended
in one common conception, and signified by one name.
I
say, do or might agree: for though there be but one
sun existing in the world, yet the idea of it being ab-
stracted, so that more substances (if there were several)
might each agree in it; it is as much a sort, as if there
were as many suns as there are stars. They want not
their reasons who think there are, and that each fixed
star would answer the idea the name sun stands for, to
one who was placed in a due distance; which, by the
way, may show us how much the sorts, or, if you please,
genera and species of things (for those Latin terms sig-
nify to me no more than the English word sort) depend
on such collections of ideas as men have made, and not
on the real nature of things; since it is not impossible
but that, in propriety of speech, that might be a sun to
one, which is a star to another.

The essence

of each sort is the abstract idea.

§ 2. The measure and boundary of each sort, or species, whereby it is constituted that particular sort, and distinguished from

others, is that we call its essence, which is nothing but that abstract idea to which the name is annexed; so that every thing contained in that idea is essential to that sort. This, though it be all the essence of natural substances that we know, or by which we distinguish them into sorts; yet I call it by a peculiar name, the nominal essence, to distinguish it from the real constitution of substances, upon which depends this nominal essence, and all the properties of that sort; which therefore, as has been said, may be called the real essence: v. g. the nominal essence of gold is that complex idea the word gold stands for, let it be, for instance, a body yellow, of a certain weight, malleable, fusible, and fixed. But the real essence is the constitution of the insensible parts of that body, on which those qualities, and all the other properties of gold depend. How far these two are different, though they are both called essence, is obvious at first sight to dis

cover.

For though perhaps volutary mo- The nominal tion, with sense and reason, joned to a and real es body of a certain shape, be the complex idea sence difto which I, and others, annex the nme man, and so be the nominal essence of the species so called; yet nobody will say that complex ica is the real es sence and source of all those operations which are to be found in any individual of that sort. The foundation of all those qualities, which are the ngredients of our complex idea, is something quite diffeent; and had we such a knowledge of that constituton of man, from which his faculties of moving, sensatio, and reasoning, and other powers flow, and on which hi so regular shape depends, as it is possible angels have, nd it is certain his Maker has; we should have a qute other idea of his essence than what now is contained in our definition of that species, be it what it will: and our idea of any individual man would be as far differnt from what it is now, as is his who knows all the springs and wheels, and other contrivances within, of the famous clock at Strasburgh, from that which a gazing countryman has for it, who barely sees the motion of the had, and hears the clock strike, and observes only some of the outward appearances.

4. That essence, in the ordinary use of the word, relates to sorts; and that it is Nothing es considered in particular beings no farther than as they are ranked into sorts; appears from hence that take but away the abstract deas, by which we sort individuals, and rank them under common names, and then the thought of any thing essential to any of them instantly vanishes; we have no notion of the one without the other; which plainly shows their relation. It is necessary for me to be as I am; God and nature has made me so: but there is nothing I have is essential to me. An accident, or disease, may very much alter my colour, or shape; a fever or fall, may take away my reason or memory, or both, and an apoplexy leave neither sense nor understanding, no nor life. Other creatures of my shape may be made with more and better, or fewer and worse faculties than I

have; and others my have reason and sense in a shape and body very differnt from mine. None of these are essential to the one or the other, or to any individual whatever, till the mnd refers it to some sort or species of things; and then presently, according to the abstract idea of that sort, something is found essential. Let any one examine his own thoughts, and he will find that as soon as h supposes or speaks of essential, the consideration of sme species, or the complex idea, signified by some geeral name, comes into his mind; and it is in reference to that, that this or that quality is said to be essental. So that if it be asked, whether it be essential to me or any other particular corporeal being to have reason? I say no; no more than it is essential to this white thing I write on to have words in it. But if that particular being be to be counted of the sort man, and to have the name man given it, thenreason is essential to it, supposing reason to be a part of the complex idea the name man stands for as it is essential to this thing I write on to contain words, if I vill give it the name treatise, and rank it under that pecies. So that essential, and not essential, relate only our abstract ideas, and the names annexed to them; vhich amounts to no more but this, that whatever particılar thing has not in it those qualities, which are contained in the abstract idea, which any general term staids for, cannot be ranked under that species, nor be caled by that name, since that abstract idea is the very essence of that species.

5. Thus, if the idea of body, with some people, be bare extension or space, then solidity is not essential to body if others make the idea, to which they give the name body, to be solidity and extension, then solidity is essential to body. That therefore, and that alone, is considered as essential, which makes a part of the complex idea the name of a sort stands for, without which no particular thing can be reckoned of that sort, nor be intitled to that name. Should there be found a parcel of matter that had all the other qualities that are in iron, but wanted obedience to the loadstone; and would neither be drawn by it, nor receive direction
