• Hédonisme = "la finalité de la vie humaine est le plaisir" (plaisir = ce qui me fait du bien)
• Eudémonisme = "la finalité de la vie humaine est le bonheur" (joie = le bien)

If you evade suffering you also evade the chance of joy. Pleasure you may get, or pleasures, but you will not be fulfilled. You will not know what it is to come home.
[...] The search for pleasure is circular, repetitive, atemporal [...], always ends in the same place. It has an end. It comes to the end and has to start over. It is not a journey and return, but a closed cycle, a locked room, a cell.
Outside the locked room is the landscape of time, in which the spirit may, with luck and courage, construct the fragile, makeshift, improbable roads and cities of fidelity. [...] Loyalty, which asserts the continuity of past and future, binding time into a whole, is the root of human strength; there is no good to be done without it.
