Just as in habiliments it is a sign of weakness to wish to make oneself noticeable by some peculiar and unaccustomed fashion, so, in language, the quest for new-fangled phrases and little-known words comes from a puerile and pedantic ambition.

Since philosophy is the art which teaches us how to live, and since children need to learn it as much as we do at other ages, why do we not instruct them in it? .. But in truth I know nothing about the philosophy of education except this: that the greatest and the most important difficulty known to human learning seems to lie in that area which treats how to bring up children and how to educate them.

The most regular and most perfect soul in the world has but too much to do to keep itself upright from being overthrown by its own weakness.

To philosophize is nothing else than to prepare oneself for death.

Whether the events in our life are good or bad, greatly depends on the way we perceive them.

The most fruitful and natural exercise for our minds is, in my opinion, conversation.

The only thing certain is nothing is certain.
