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

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.

All just order in the world is based on this, that man give man what is his due.

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 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.

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

... the greatest menace to our capacity for contemplation is the incessant fabrication of tawdry empty stimuli which kill the receptivity of the soul.
