Whereas, were the capacities of our understandings well considered, the extent of our knowledge once discovered, and the horizon found which sets the bounds between the enlightened and dark parts of things; between what is and what is not comprehensible by us, men would perhaps with less scruple acquiesce in the avowed ignorance of the one, and employ their thoughts and discourse with more advantage and satisfaction in the other.

What Idea stands for.
Thus much I thought necessary to say concerning the occasion of this inquiry into human Understanding.

But, before I proceed on to what I have thought on this subject, I must here in the entrance beg pardon of my reader for the frequent use of the word IDEA, which he will find in the following treatise.

It being that term which, I think, serves best to stand for whatsoever is the OBJECT of the understanding when a man thinks, I have used it to express whatever is meant by PHANTASM, NOTION, SPECIES, or WHATEVER IT IS WHICH THE MIND CAN BE EMPLOYED ABOUT IN THINKING; and I could not avoid frequently using it.

I presume it will be easily granted me, that there are such IDEAS in men's minds: every one is conscious of them in himself; and men's words and actions will satisfy him that they are in others.
Our first inquiry then shall be,--how they come into the mind.
