Wonder is defined by Thomas [Aquinas] in the Summa Theologiae [I-II, Q. 32, a. 8], as the desiderium sciendi, the desire for knowledge, active longing to know.

What distinguishes - in both senses of that word - contemplation is rather this: it is a knowing which is inspired by love. "Without love there would be no contemplation." Contemplation is a loving attainment of awareness. It is intuition of the beloved object.

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.

... 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. It is immediately evident that such satisfactions are not enough; they are not what we have really sought; they cannot really satisfy us at all.

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

The ultimate meaning of the active life is to make possible the happiness of contemplation.

Only the silent hear and those who do not remain silent do not hear.
