sent to them all those parts, where he could neither feel nor perceive any thing.

§. 13. He that should use the word rainbow to one who knew all those colours, but yet had never seen that phænomenon, would, by enumerating the figure, largeness, position and order of the colours, so well define that word, that it might be perfectly understood. But yet that definition, how exact and perfect soever, would never make a blind man understand it; because several of the simple ideas that make that complex one, being such as he never received by sensation and experience, no words are able to excite them in his mind.

§. 14. Simple ideas, as has been showed, The same can only be got by experience, from those of complex objects, which are proper to produce in us ideas when those perceptions. When by this means we to be made have our minds stored with them, and know intelligible by words. the names for them, then we are in a condition to define, and by definition to understand the names of complex ideas, that are made up of them. But when any term stands for a simple idea, that a man has never yet had in his mind, it is impossible by any words to make known its meaning to him. When any term stands for an idea a man is acquainted with, but is ignorant that that term is the sign of it; there another name, of the same idea which he has been accustomed to, may make him understand its meaning. But in no case whatsoever is any name, of any simple idea, capable of a definition.

§. 15. Fourthly, But though the names 4. Names of of simple ideas, have not the help of defini- simple ideas tion to determined their signification, yet least doubtthat hinders not but that they are generally > less doubtful and uncertain, than those of mixed modes and substances: because they standing only for one simple perception, men, for the most part, easily and perfectly agree in their signification; and there is little room for mistake and wrangling about their meaning. He that knows once that whiteness is the name of that colour he has observed in snow or milk, will not be

apt to misapply that word, as long as he retains that idea; which when he has quite lost, he is not apt to mistake the meaning of it, but perceives he under stands it not. There is neither a multiplicity of simple ideas to be put together, which makes the doubtfulness in the names of mixed modes; nor a supposed, but an unknown real essence, with properties depending thereon, the precise number whereof is also unknown, which makes the difficulty in the names of substances, But, on the contrary, in simple ideas the whole signification of the name is known at once, and consists not of parts, whereof more or less being put in, the idea may be varied, and so the signification of name be obscure or uncertain.

5. Simple ideas have few ascents

§. 16. Fifthly, This farther may be ob served concerning simple ideas and their names, that they have but few ascents in in lineâ præ- lineâ prædicamentali (as they call it) from dicamentali. the lowest species to the summum genus. The reason whereof is, that the lowest species being but one simple idea, nothing can be left out of it; that so the difference being taken away it may agree with some other thing in one idea common to them both; which, having one name, is the genus of the other two: v. g. there is nothing that can be left out of the idea of white and red, to make them agree in one common appearance, and so have one general name; as rationality being left out of the complex idea of man, makes it agree with brute, in the more general idea and name of animal: and therefore when to avoid unpleasant enumerations, men would comprehend both white and red, and several other such simple ideas, under one general name, they have been fain to do it by a word, which denotes only the way they get into the mind. For when white, red, and yellow, are all com prehended under the genus or name colour, it signifies no more but such ideas as are produced in the mind only by the sight, and have entrance only through the eyes. And when they would frame yet a more general term, to comprehend both colours and sounds, and the like simple ideas, they do it by a word that signifies all

such as come into the mind only by one sense: and so the general term quality, in its ordinary acceptation, comprehends colours, sounds, tastes, smells, and tangible qualities, with distinction from extension, number, motion, pleasure and pain, which make impressions on the mind, and introduce their ideas by more senses than one.

§. 17. Sixthly, The names of simple ideas, 6. Names of substances, and mixed modes have also this simple ideas difference; that those of mixed modes stand not at all ar for ideas perfectly arbitrary; those of sub- bitrary. stances are not perfectly so, but refer to a pattern, though with some latitude; and those of simple ideas are perfectly taken from the existence of things, and are not arbitrary at all. Which, what difference it makes in the significations of their names, we shall see in the following chapters.

The names of simple modes differ little from those of simple ideas.

ral names.

§. 1. THE names of mixed modes be- They stand ing general, they stand, as has been shown, for abstract for sorts or species of things, each of which ideas, as has its peculiar essence. The essences of other gene. these species also, as has been showed, are nothing but the abstract ideas in the mind, to which the name is annexed. Thus far the names and essences of mixed modes have nothing but what is common to them with other ideas: but if we take a little nearer survey of them, we shall find that they have something peculiar, which perhaps may deserve our

attention.

1. The ideas they stand for are made by the understanding.

§. 2. The first particularity I shall observe in them, is, that the abstract ideas, or, if you please, the essences of the several species of mixed modes are made by the understanding, wherein they differ from those of simple ideas: in which sort the mind has no power to make any one, but only receives such as are presented to it, by the real existence of things, operating upon it.

2. Made arbitrarily,

patterns.

§. 3. In the next place, these essences of the species of mixed modes are not only and without made by the mind, but made very arbitrarily, made without patterns, or reference to any real existence. Wherein they differ from those of substances, which carry with them the supposition of some real being, from which they are taken, and to which they are conformable. But in its complex ideas of mixed modes, the mind takes a liberty not to follow the existence of things exactly. It unites and retains certain collections, as so many distinct specific ideas, whilst others, that as often occur in nature, and are as plainly suggested by outward things, pass neglected, without particular names or specifications. Nor does the mind, in these of mixed modes, as in the complex idea of substances, examine them by the real existence of things; or verify them by patterns, containing such peculiar compositions in nature. To know whether his idea of adultery or incest be right, will a man seek it any where amongst things existing? Or is it true, because any one has been witness to such an action? No: but it suffices here, that men have put together such a collection into one complex idea, that makes the archetype and specific idea, whether ever any such action were committed in rerum natura or no..

How this is done.

§. 4. To understand this right, we must consider wherein this making of these complex ideas consists; and that is not in the making any new idea, but putting together those which the mind had before. Wherein the mind does these three things: first, it chooses a certain number: secondly, it gives them connexion, and makes them into one idea:

thirdly, it ties them together by a name. If we examine how the mind proceeds in these, and what liberty it takes in them, we shall easily observe how these essences of the species of mixed modes are the workmanship of the mind; and consequently, that the species themselves are of men's making.

§. 5. Nobody can doubt, but that these Evidently ideas of mixed modes are made by a vo- arbitrary, in luntary collection of ideas put together in that the idea the mind, independent from any original is often before the expatterns in nature, who will but reflect istence. that this sort of complex ideas may be made, abstracted, and have names given them, and so a species be constituted, before any one individual of that species ever existed. Who can doubt but the ideas of sacrilege or adultery might be framed in the minds of men, and have names given them; and so these species of mixed modes be constituted, before either of them was ever committed; and might be as well discoursed of and reasoned about, and as certain truths discovered of them, whilst yet they had no being but in the understanding, as well as now, that they have but too frequently a real existence? Whereby it is plain, how much the sorts of mixed modes are the creatures of the understanding, where they have a being as subservient to all the ends of real truth and knowledge, as when they really exist: and we cannot doubt but lawmakers have often made laws about species of actions, which were only the creatures of their own understandings; beings that had no other existence but in their own minds. And I think nobody can deny, but that the resurrection was a species of mixed modes in the mind, before it really existed. :

To see how arbitrarily these essences Instances; of mixed modes are made by the mind, we murder, inneed but take a view of almost any of them. cest, stabA little looking into them will satisfy us, that it is the mind that combines several scattered independent ideas into one complex one, and, by the common name it gives them, makes them the essence of a certain species, without regulating itself by any connexion they have in nature.
