The wisdom which knows what are and are not dangers is opposed to the ignorance of them - Plato

He who is only an athlete is too crude, too vulgar, too much a savage. He who is a scholar only is too soft, to effeminate. The ideal citizen is the scholar athlete, the man of thought and the man of action.

Knowledge is the food of the soul; and we must take care, my friend, that the Sophist does not deceive us when he praises what he sells, like the dealers wholesale or retail who sell the food of the body; for they praise indiscriminately all their goods, without knowing what are really beneficial or hurtful.

...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.
