The soul is perfected by knowledge and virtue.

It is only God who creates. Man merely rearranges.

A scrap of knowledge about sublime things is worth more than any amount about trivialities.

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.

You change people by delight, by pleasure.

I answer that, Even, as in the blessed in heaven there will be most perfect charity, so in the damned there will be the most perfect hate.

True peace consists in not separating ourselves from the will of God.
