Of pleasure, or delights, some arise from the sense of an object present; and those may be called pleasures of sense....Of this kind are onerations and exonerations of the body; as also all that is pleasant, in the sight, hearing, smell, taste, or touch; others arise from the expectation, that proceeds from foresight of the end, or consequence of things; whether those things in the sense please or displease: and these are pleasures of the mind of him that draweth those consequences and are generally called JOY. In the like manner, displeasures, are some in the sense, and called PAIN; others, in the expectation of consequences, and are called GRIEF. [Leviathan I, VI, 12]

This endeavour, when it is toward something which causes it is called APPETITE, or DESIRE; the latter, being the general name; and the other oftentimes restrained to signify the desire of food....And when the endeavour is fromward something it is generally called AVERSION. [Leviathan, I, VI, 2]
