A strong belief in fate is the worst kind of slavery; on the other hand, there is a comfort in the thought that God will be moved by our prayers.

All other love is extinguished by self-love; beneficence, humanity, justice, philosophy, sink under it.

All sensations are true; pleasure is our natural goal.

There is no such thing as justice in the abstract; it is merely a compact between men in their various relations with each other, in whatever circumstances they may be, that they will neither injure nor be injured.

Neither one should hesitate about dedicating oneself to philosophy when young, nor should get tired of doing it when one's old, because no one is ever too young or too old to reach one's soul's healthy.

Why should I fear death? If I am, death is not. If death is, I am not. Why should I fear that which can only exist when I do not?

Let no one be slow to seek wisdom when he is young nor weary in the search of it when he has grown old. For no age is too early or too late for the health of the soul.
