The "supreme good" and its attainment -- that is happiness. And joy is: response to happiness.

[T]o know means to reach the reality of existing things[.]

No one can obtain felicity by pursuit. This explains why one of the elements of being happy is the feeling that a debt of gratitude is owed, a debt impossible to pay. Now, we do not owe gratitude to ourselves. To be conscious of gratitude is to acknowledge a gift.

Unless we regain the art of silence and insight, the ability for nonactivity, unless we substitute true leisure for our hectic amusements, we will destroy our culture and ourselves.

The happy life does not mean loving what we possess, but possessing what we love." Possession of the beloved, St. Thomas holds, takes place in an act of cognition, in seeing, in intuition, in contemplation.

If in this supreme test, in face of which the braggart falls silent and every heroic gesture is paralyzed, a man walks straight up to the cause of his fear and is not deterred from doing that which is good -- which ultimately means for the sake of God, and therefore not from ambition or from fear of being taken for a coward -- this man, and he alone, is truly brave.
