When he awakens to the world, does not man feel, in addition to the natural desire to understand and take possession of it, the desire to find within it his fulfillment and happiness? As everyone knows, there are several degrees of this "happiness." Its most noble expression is joy, or "happiness" in the strict sense, when man, on the level of his higher faculties, finds his peace and satisfaction in the possession of a known and loved good. Thus, man experiences joy when he finds himself in harmony with nature, and especially in the encounter, sharing and communion with other people. (Papal Writings, Gaudete in Domino: On Christian Joy, 9 May 1975).
