A rational nature admits of nothing but what is serviceable to the rest of mankind.

Natural ability without education has more often raised a man to glory and virtue than education without natural ability.

Without a purpose, nothing should be done.

When you arise in the morning, think of what a precious privilege it is to be alive - to breathe, to think, to enjoy, to love.

Nothing happens to any man which he is not formed by nature to bear. The same things happen to another, and either because he does not see that they have happened or because he would show a great spirit he is firm and remains unharmed. It is a shame then that ignorance and conceit should be stronger than wisdom.

The happiness and unhappiness of the rational, social animal depends not on what he feels but on what he does; just as his virtue and vice consist not in feeling but in doing.

Whoever values peace of mind and the health of the soul will live the best of all possible lives.
