And although unstudied men, doe not conceive any motion at all to be there, where the thing moved is invisible; or the space it is moved in, is (for the shortnesse of it) insensible; yet that doth not hinder, but that such Motions are.

For let a space be never so little, that which is moved over a greater space, whereof that little one is part, must first be moved over that.

These small beginnings of Motion, within the body of Man, before they appear in walking, speaking, striking, and other visible actions, are commonly called ENDEAVOUR.
Endeavour; Appetite; Desire; Hunger; Thirst; Aversion 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.
