The common element in all the special forms of contemplation is the loving, yearning, affirming bent toward that happiness which is the same as God Himself, and which is the aim and purpose of all that happens in the world.

Justice is a habit (habitus), whereby a man renders to each one his due with constant and perpetual will.

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.

The happy man needs nothing and no one. Not that he holds himself aloof, for indeed he is in harmony with everything and everyone; everything is "in him"; nothing can happen to him. The same may also be said for the contemplative person; he needs himself alone; he lacks nothing.

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.

Happiness is essentially a gift; we are not the forgers of our own felicity.

Modern religious teaching have little or nothing to say about the place of prudence in life or in the hierarchy of virtues.
