Music is a more potent instrument than any other for education.

Love: a grave mental disease.

Nothing more excellent or valuable than wine was every granted by the gods to man.

All learning is in the learner, not the teacher.

Rhythm and melody enter into the soul of the well-instructed youth and produce there a certain mental harmony hardly obtainable in any other way. . . . thus music, too, is concerned with the principles of love in their application to harmony and rhythm.

Writing is the geometry of the soul.

The cure of the part should not be attempted without treatment of the whole. No attempt should be made to cure the body without the soul. Let no one persuade you to cure the head until he has first given you his soul to be cured, for this is the great error of our day, that physicians first separate the soul from the body.
