Plato

“Socrates:...For when I say beauty of form, I am trying to express, not what most people would understand by the words, such as the beauty of animals or of paintings, but I mean, says the argument, the straight line and the circle and the plane and solid figures formed from these by turning-lathes and rulers and patterns of angles; perhaps you understand. For I assert that the beauty of these is not relative, like that of other things, but they are always absolutely beautiful by nature.”

“Is it anything else than the separation of the soul from the body? Do we believe that death is this, namely, that the body comes to be separated by itself apart from the soul, and the soul comes to be separated by itself apart from the body? Is death anything else than that?”

“If "love" is understood as or as rooted in wanting or desire, then, since "to want" is (in its original sense) "to lack," it would seem to follow that love must begin with lacking: one desires what one does not already have. Incidentally, this definition would completely negate the possibility of divine love! Love is simply the name for the desire and pursuit of the whole.”

“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.”
