Misanthropy ariseth from a man trusting another without having sufficient knowledge of his character, and, thinking him to be truthful, sincere, and honourable, finds a little afterwards that he is wicked, faithless, and then he meets with another of the same character. When a man experiences this often, and more particularly from those whom he considered his most dear and best friends, at last, having frequently made a slip, he hates the whole world, and thinks that there is nothing sound at all in any of them.
PlatoRhythm 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.
PlatoThe principles are important. First, the interest of the state or society counts for everything, that of the individual for nothing. Second, the only difference between men and women is one of physical function- one begets, the other bears children. Apart from that, they both can and should perform the same functions - though men on a whole, perform them better and should receive the same education to enable them to do so; for in this way society will get the best value from both.
