Love: a grave mental disease.

The flute is not an instrument that has a good moral effect - it is too exciting.

And so, when a person meets the half that is his very own, whatever his orientation, whether it's to young men or not, then something wonderful happens: the two are struck from their senses by love, by a sense of belonging to one another, and by desire, and they don't want to be separated from one another, not even for a moment.

The cure of many diseases is unknown to physicians because they are ignorant of the whole... For the part can never be well unless the whole is well.

The good man is the only excellent musician, because he gives forth a perfect harmony not with a lyre or other instrument but with the whole of his life.

When the mind is thinking it is talking to itself.
