Wonder is the desire of knowledge.

Happiness is secured through virtue; it is a good attained by man's own will.

To one who has faith, no explanation is necessary. To one without faith, no explanation is possible.

Bestow upon me, O Lord my God, understanding to know thee, diligence to seek thee, wisdom to find thee, and a faithfulness that may finally embrace thee.

We set forth our petitions before God, not in order to make known to Him our needs and desires, but rather so that we ourselves may realize that in these things it is necessary to turn to God for help.

It would be superfluous to receive by faith, things that can be known by natural reason

If there were some solitary or feral man, the passions of the soul would be sufficient for him; by them he would be conformed to things in order that he might have knowledge of them. But because man is naturally political and social, there is need for one man to make his conceptions known to others, which is done with speech. So significant speech was needed if men were to live together. Which is why those of different tongues do not easily live together.
