Music and rhythm find their way into the secret places of the soul

Mankind censure injustice fearing that they may be the victims of it, and not because they shrink from committing it.

Courage is knowing what to fear.

For the poets tell us, don't they, that the melodies they bring us are gathered from rills that run with honey, out of glens and gardens of the Muses, and they bring them as bees do honey, flying like the bees? And what they say is true, for a poet is a light and winged thing, and holy, and never able to compose until he has become inspired, and is beside himself, and reason is no longer in him. So long as he has this in his possession, no man is able to make poetry or to chant in prophecy.

Numbers are the highest degree of knowledge. It is knowledge itself.

We will be better men, braver and less idle, if we believe that one must search for the things one does not know, rather than if we believe that it is not possible to find out what we do not know and that we must not look for it.

We are like people looking for something they have in their hands all the time; we're looking in all directions except at the thing we want, which is probably why we haven't found it.
