Our affections as well as our bodies are in perpetual flux.

Teach by doing whenever you can, and only fall back upon words when doing it is out of the question.

Our greatest evils flow from ourselves.

[When anything happens, we interpret it as good or bad, but...] We do not know what is really good or bad fortune. [Only the future can decide. For example, what appears to be bad today may in fact lead us to a greater good tomorrow and by the very act of thinking and planning in that positive way, we can help make that good future come true.]

The problem is to find a form of association which will defend and protect with the whole common force the person and goods of each associate, and in which each, while uniting himself with all, may still obey himself alone, and remain as free as before.

To abstain that we may enjoy is the epicurianism of reason.

Leave those vain moralists, my friend, and return to the depth of your soul: that is where you will always rediscover the source of the sacred fire which so often inflamed us with love of the sublime virtues; that is where you will see the eternal image of true beauty, the contemplation of which inspires us with a holy enthusiasm.
