Music is good to the melancholy, bad to those who mourn, and neither good nor bad to the deaf

One and the same thing can at the same time be good, bad, and indifferent, e.g., music is good to the melancholy, bad to those who mourn, and neither good nor bad to the deaf.

It is the part of a wise man, I say, to refresh and restore himself in moderation with pleasant food and drink, with scents, with the beauty of green plants, with decoration, music, sports, the theater, and other things of this kind, which anyone can use without injury to another.

All things excellent are as difficult as they are rare.

The world would be happier if men had the same capacity to be silent that they have to speak.

Nothing in the universe is contingent, but all things are conditioned to exist and operate in a particular manner by the necessity of the divine nature.
