Material things have closed boundaries; they are not accessible, cannot be penetrated, by things outside themselves. But one's existence as a spiritual being involves being and remaining oneself and at the same time admitting and transforming into oneself the reality of the world. No other material thing can be present in the space occupied by a house, a tree, or a fountain pen. But where there is mind, the totality of things has room; it is "possible that in a single being the comprehensiveness of the whole universe may dwell.

... each gratification points to the ultimate one, and that all happiness has some connection with eternal beatitude. Some connection, if only this: that every fulfillment this side of Heaven instantly reveals its inadequacy.

The delight we take in our senses is an implicit desire to know the ultimate reason for things, the highest cause. The desire for wisdom that philosophy etymologically is is a desire for the highest or divine causes. Philosophy culminates in theology. All other knowledge contains the seeds of contemplation of the divine.

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.

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.

Repose, leisure, peace, belong among the elements of happiness. If we have not escaped from harried rush, from mad pursuit, from unrest, from the necessity of care, we are not happy. And what of contemplation? Its very premise is freedom from the fetters of workaday busyness. Moreover, it itself actualizes this freedom by virtue of being intuition.

The essence of leisure is not to assure that we may function smoothly but rather to assure that we, embedded in our social function, are enabled to remain fully human.
