to think every one, who uses, does not perfectly understand. And possibly it is but here and there one, who gives himself the trouble to consider them so far as to know what he himself or others precisely mean by them: I have therefore in most places chose to put determinate or determined, instead of clear and distinct, as more likely to direct men's thoughts to my meaning in this matter. By those denominations, I mean some object in the mind, and consequently determined, i. e. such as it is there seen and perceived to be. This, I think, may fitly be called a determinate or determined idea, when such as it is at any time objectively in the mind, and so determined there, it is annexed, and without variation determined to a name or articulate sound, which is to be steadily the sign of that very same object of the mind or determinate idea.
To explain this a little more particularly. By determinate, when applied to a simple idea, I mean that simple appearance which the mind has in its view, or perceives in itself, when that idea is said to be in it: by determinate, when applied to a complex idea, I mean such an one as consists of a determinate number of certain simple or less complex ideas, joined in such a proportion and situation, as the mind has before its view, and sees in itself, when that idea is present in it, or should be present in it, when a man gives a name to it: I say should be; because it is not every one, not perhaps any one, who is so careful of his language, as to use no word, till he views in his mind the precise determined idea, which he resolves to make it the sign of. The want of this is the cause of no small obscurity and confusion in men's thoughts and discourses.
I know there are not words enough in any language to answer all the variety of ideas that enter into men's discourses and reasonings. But this hinders not, but that when any one uses any term, he may have in his mind a determined idea, which he makes it the sign of, and to which he should keep it steadily annexed, during that present discourse. Where he does not, or
