Epicureans further separate pleasure into what they call kinetic and katastematic pleasures. Kinetic pleasures are those pleasures which come about through action or change. Such an action could be satisfying a desire or removing a pain, as that very sort of act is pleasurable in itself. Actions that feel good, even if not done to satisfy a desire or remove a pain, such as eating good-tasting food, also fall under the category of kinetic pleasures. Mental pleasures could also be kinetic in nature. Epicurus is said to have described joy as an example of a kinetic mental pleasure.
