ginning of a man's ideas is the same as to inquire after the beginning of his soul: for by this account soul and its ideas, as body and its extension, will begin to exist both at the same time.
The soul thinks not always; for this wants proofs.§ 10. But whether the soul be supposed to exist antecedent to, or coeval with, or some time after the first rudiments of organization, or the beginnings oi lite in the body, I leave to be disputed by those who have better thought of that matter. I confess myself to have one of those dull souls, that doth not perceive itself always to contemplate ideas, nor can conceive it any more necessary for the soul always to think, than for the body always to move; the perception of ideas being (as I conceive) to the soul, what motion is to the body, not its essence, but one of its operations. And therefore, though thinking be supposed ever so much the proper action of the soul, yet it is not necessary to suppose that it should be always thinking, always in action. That perhaps is the privilege of the infinite Author and Preserver of things, who never slumbers nor sleeps; but it is not competent to any finite being, at least not to the soul of man. We know certainly by experience that we sometimes think, and thence draw this infallible consequence, that there is something in us that has a power to think: but whether that substance perpetually thinks or no, we can be no farther assured than experience informs us. For to say that actual thinking is essential to the soul, and inseparable from it, is to beg what is in question, and not to prove it by reason; which is necessary to be done, if it be not a self-evident proposition. But whether this, "that the soul always thinks," be a self-evident proposition, that every body assents to at first hearing, I appeal to mankind. It is doubted whether I thought at all last night or no; the question being about a matter of fact, it is begging it to bring, as a proof for it, an hypothesis, which is the very thing in dispute; by which way one may prove any thing:
