There is a ... matter - much more valuable and divine than natural philosophy . ... On this matter I must speak to you in enigmas.
PlatoAs a breath of wind or some echo rebounds from smooth, hard surfaces and returns to the source from which it issued, so the stream of beauty passes back into its possessor through his eyes, which is its natural route to the soul; arriving there and setting him all aflutter, it waters the passages of the feathers and causes the wings to grow, and fills the soul of the loved one in his turn with love.
PlatoThe true lover of learning then must his earliest youth, as far as in him lies, desire all truth.... He whose desires are drawn toward knowledge in every form will be absorbed in the pleasures of the soul, and will hardly feel bodily pleasures I mean, if he be a true philosopher and not a sham one ... Then how can he who has the magnificence of mind and is the spectator of all times and all existence, think much of human life He cannot. Or can such a one account death fearful No indeed.
