For it is obvious to everybody, I think, that this study [of astronomy] compels the soul to look upward and leads it away from things here to higher things.
Beauty of style and harmony and grace and good rhythm depend on simplicity - I mean the true simplicity of a rightly and nobly ordered mind and character, not that other simplicity which is only a euphemism for folly.
My good friend, you are a citizen of Athens, a city which is very great and very famous for its wisdom and power - are you not ashamed of caring so much for the making of money and for fame and prestige, when you neither think nor care about wisdom and truth and the improvement of your soul?

The souls of people, on their way to Earth-life, pass through a room full of lights; each takes a taper - often only a spark - to guide it in the dim country of this world. But some souls, by rare fortune, are detained longer - have time to grasp a handful of tapers, which they weave into a torch. These are the torch-bearers of humanity - its poets, seers and saints, who lead and lift the race out of darkness, toward the light. They are the law-givers and saviors, the light-bringers, way-showers and truth-tellers, and without them, humanity would lose its way in the dark.
All soul is immortal. For that which is always in movement is immortal; that which moves something else, and is moved by something else, in ceasing from movement ceases from living. So only that which moves itself, because it does not abandon itself, never stops moving. But it is also source and first principle of movement for the other things which move.
