We ought not to listen to those who exhort us, because we are human, to think of human things....We ought rather to take on immortality as much as possible, and do all that we can to live in accordance with the highest element within us; for even if its bulk is small, in its power and value it far exceeds everything.

Whether we call it sacrifice, or poetry, or adventure, it is always the same voice that calls.

Music has a power of forming the character, and should therefore be introduced into the education of the young.

No tyrant need fear till men begin to feel confident in each other.

Quid quid movetur ab alio movetur"(nothing moves without having been moved).

If, then, there is some end of the things we do, which we desire for its own sake (everything else being desired for the sake of this), and if we do not choose everything for the sake of something else (for at that rate the process would go on to infinity, so that our desire would be empty and vain), clearly this must be the good and the chief good.

We must not feel a childish disgust at the investigations of the meaner animals. For there is something marvelous in all natural things.
