This Endeavour, when it is toward something which causes it, is called APPETITE, or DESIRE; the later, being the generall name; and the other, oftentimes restrayned to signifie the Desire of Food, namely Hunger and Thirst. And when the Endeavour is fromward something, it is generally called AVERSION. These words Appetite, and Aversion we have from the Latines; and they both of them signifie the motions, one of approaching, the other of retiring. So also do the Greek words for the same, which are orme and aphorme. For nature it selfe does often presse upon men those truths, which afterwards, when they look for somewhat beyond Nature, they stumble at. For the Schooles find in meere Appetite to go, or move, no actuall Motion at all: but because some Motion they must acknowledge, they call it Metaphoricall Motion; which is but an absurd speech; for though Words may be called metaphoricall; Bodies, and Motions cannot.

That which men Desire, they are also sayd to LOVE; and to HATE those things, for which they have Aversion. So that Desire, and Love, are the same thing; save that by Desire, we alwayes signifie the Absence of the object; by Love, most commonly the Presence of the same. So also by Aversion, we signifie the Absence; and by Hate, the Presence of the Object.

Of Appetites, and Aversions, some are born with men; as Appetite of food, Appetite of excretion, and exoneration, (which may also and more properly be called Aversions, from somewhat they feele in their Bodies;) and some other Appetites, not many. The rest, which are Appetites of particular things, proceed from Experience, and triall of their effects upon themselves, or other men. For of things wee know not at all, or believe not to be, we can have no further Desire, than to tast and try. But Aversion wee have for things, not onely which we know have hurt us; but also that we do not know whether they will hurt us, or not.
