Many are the noble words in which poets speak concerning the actions of men; but like yourself when speaking about Homer, they do not speak of them by any rules of art: they are simply inspired to utter that to which the Muse impels them, and that only; and when inspired, one of them will make dithyrambs, another hymns of praise, another choral strains, another epic or iambic verses- and he who is good at one is not good any other kind of verse: for not by art does the poet sing, but by power divine.
Harmony sinks deep into the recesses of the soul and takes its strongest hold there, bringing grace also to the body & mind as well. Music is a moral law. It gives a soul to the universe, wings to the mind, flight to the imagination, a charm to sadness, and life to everything. It is the essence of order.
Consider how great is the encouragement which all the world gives to the lover; neither is he supposed to be doing anything dishonourable; but if he succeeds he is praised, and if he fail he is blamed.
The cause of all the blunders committed by man arises from this excessive self-love. For the lover is blinded by the object loved; so that he passes a wrong judgment on what is just, good and beautiful, thinking that he ought always to honor what belongs to himself in preference to truth. For he who intends to be a great man ought to love neither himself nor his own things, but only what is just, whether it happens to be done by himself, or by another.
If in a discussion of many matters ... we are not able to give perfectly exact and self-consistent accounts, do not be surprised: rather we would be content if we provide accounts that are second to none in probability.
