Even the heavens are open to the mind of Man. Man alone of all the animals has traced the pathways of the rising and the setting of the stars. Man has measured out the days and months and years. Man alone has understood and can predict the eclipses of the sun and moon for all future time, when they will occur, and whether they will be partial or total. When the mind contemplates these phenomena, it learns also knowledge of the gods. So religion is born, and with it goodness and all the virtues which make up the good life, a life which reflects the divine life. We need to be inferior to the gods in nothing except our mortality, which need in no way hinder us from living well. In explaining these things, I think that I have shown clearly enough how much superior is human nature to that of all the other animals. From which we must infer that such a shape and arrangement of our limbs and such a power of intelligence cannot have been the work of chance alone.

The wise are instructed by reason, average minds by experience, the stupid by necessity and the brute by instinct.

The greatest states have been overthrown by the young and sustained and restored by the old. ... Rashness is the product of the budding-time of youth, prudence of the harvest-time of age.
