Whatever we learn to do, we learn by actually doing it; men come to be builders, for instance, by building, and harp players by playing the harp. In the same way, by doing just acts we come to be just; by doing self-controlled acts, we come to be self-controlled ; and by doing brave acts, we become brave.

He who can be, and therefore is, another's, and he who participates in reason enough to apprehend, but not to have, is a slave by nature.

Adventure is worthwhile.

Even that some people try deceived me many times ... I will not fail to believe that somewhere, someone deserves my trust.

Prayers and sacrifices are of no avail.

What is the essence of life? To serve others and to do good.
