Beauty of style and harmony and grace and good rhythm depend on simplicity - Plato

The man who finds that in the course of his life he has done a lot of wrong often wakes up at night in terror, like a child with a nightmare, and his life is full of foreboding: but the man who is conscious of no wrongdoing is filled with cheerfulness and with the comfort of old age.

I will tell you, in order that you may not share the impiety of the multitude: for there cannot conceivably be anything more impious or more to be guarded against than being mistaken in word and deed with regard to the gods, and after them, with regard to divine men; you must take very great precaution, whenever you are about to blame or praise a man, so as not to speak incorrectly. For this reason you must learn to distinguish honest and dishonest men: for God feels resentment when one blames a man who is like himself, or praises a man who is the opposite; and the former is the good man. For you must not suppose that while stocks and stones and birds and snakes are sacred, men are not; nay, the good man is the most sacred of all these things, and the wicked man is the most defiled.

...when he looks at Beauty in the only way that Beauty can be seen - only then will it become possible for him to give birth not to images of virtue (because he's in touch with no images), but to true virtue [arete] (because he is in touch with true Beauty). The love of the gods belongs to anyone who has given to true virtue and nourished it, and if any human being could become immortal, it would be he.
