Joy is not the satisfied contemplation of an accomplished result, the emotion of victory, the satisfaction of having succeeded. It is the sign of an energy that is deftly deployed, it is a free affirmation: everything comes easy. Joy is an activity: executing with case something difficult that has taken time to master, asserting the faculties of the mind and the body. Joys of thought when it ﬁnds and discovers, joys of the body when it achieves without effort. That is why joy, unlike pleasure, increases with repetition, and is enriched.
