1. The succession of conceptions in the mind, their series or consequence of one after another, may be casual and incoherent, as in dreams for the most part; and it may be orderly, as when the former thought introduceth the latter; and this is discourse of the mind. But because the word discourse is commonly taken for the coherence and consequence of words, I will (to avoid equivocation) call it DISCURSION.
2. The cause of the coherence or consequence of one conception to another, is their first coherence, or consequence at that time when they were produced by sense. As for example: from St. Andrew the mind runneth to St. Peter, because their names are read together; from St. Peter to a stone, for the same cause; from stone to foundation, because we see them together; and for the same cause, from foundation to church, from church to people, and from people to tumult. And according to this example, the mind may run almost from any thing to any thing. But as to the sense the conception of cause and effect succeed one another. so may they after sense in the imagination. And for the most part they do so. The cause whereof is the appetite of them, who, having a conception of the end, have next unto it a conception of the next means to that end. As when a man, from the thought of honour to which he hath an appetite, cometh to the thought of wisdom, which is the next means thereto; and from thence to the thought of study, which is the next means to wisdom, etc.
3. To omit that kind of discursion by which we proceed from any thing to any thing, there are of the other kind divers sorts.
As first in the senses: there are certain coherences of conceptions, which we may call RANGING. Examples whereof are: a man's casting his eye upon the ground, to look about for some small thing lost; the hounds casting about at a fault in hunting; and the ranging of spaniels. And herein we take a beginning arbitrarily.
4. Another sort of discursion is, when the appetite giveth a man his beginning, as in the example before adduced: where honour, to which a man hath appetite, maketh him to think upon the next means of attaining it, and that again of the next, &c.
And this the Latins call sagacitas, SAGACITY, and we may call it hunting or tracing, as dogs trace the beast by the smell, and men hunt them by their footsteps; or as men hunt after riches, place, or knowledge.
5. There is yet another kind of discursion beginning with appetite to recover something lost, proceeding from the present backward, from the thought of the place where we miss it, to the thought of the place from whence we came last; and from the thought of that, to the thought of a place before, till we have in our mind some place, wherein we had the thing we miss: and this is called REMINISCENCE.
6. The remembrance of the succession of one thing to another, that is, of what was antecedent, and what consequent, and what concomitant, is called an EXPERIMENT; whether the same be made by us voluntarily, as when a man putteth any thing into the fire, to see what effect the fire will produce upon it; or not made by us, as when we remember a fair morning after a red evening. To have had many experiments, is that we call EXPERIENCE, which is nothing else but remembrance of what antecedents have been followed with what consequents.
