[Sidenote: Sagacity.] 4. Another sort of discursion is, when the _appetite_ giveth a man his beginning, as in the example before, where honour to which a man hath appetite, maketh him think upon the next means of attaining it, and that again of the next, &c. And this the Latins call _sagacitas_, and we may call _hunting_ or _tracing_, as dogs trace beasts by the smell, and men hunt them by their footsteps; or as men hunt after riches, place, or knowledge. [Sidenote: Reminiscence.] 5. There is yet another kind of discursion beginning with the appetite to _recover_ something lost, proceeding from the _present backward_, from thought of the place where we _miss_ at, 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_. [Sidenote: Experience.] 6. The _remembrance_ of 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 by what consequents. [Sidenote: Expectation.] 7. No man can have in his mind a conception of the _future_, for the future is _not yet_: but of our conceptions of the _past_, we make a _future_; or rather, call _past_, _future_ relatively. Thus after a man hath been accustomed to see like antecedents followed by like consequents, whensoever he seeth the like come to pass to any thing he had seen before, he looks there should follow it the same that followed then: as for example, because a man hath often seen offences followed by punishment, when he seeth an offence in present, he thinketh punishment to be consequent thereto; but consequent unto that which is present, men call future; and thus we make _remembrance_ to be the _prevision_ of things to come, or _expectation_ or presumption of the future. [Sidenote: Conjecture.] 8. In the same manner, if a man seeth in present that which he hath seen before, he thinks that that which was antecedent to that which he saw before, is also antecedent to that he presently seeth: as for example, he that hath seen the ashes remain after the fire, and now again seeth ashes, concludeth again there hath been fire: and this is called again _conjecture_ of the past, or presumption of the fact.
