if someone got to see the Beautiful itself, absolute, pure, unmixed, not polluted by human flesh or colors or any other great nonsense of mortality, … - Plato

...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.

οἷον πνεῦμα ἤ τις ἠχὼ ἀπὸ λείων τε καὶ στερεῶν ἁλλομένη πάλιν ὅθεν ὡρμήθη φέρεται, οὕτω τὸ τοῦ κάλλους ῥεῦμα πάλιν εἰς τὸν καλὸν διὰ τῶν ὀμμάτων ἰόν

"Here's something else I'd like your opinion about," I said. "If he went back underground and sat down again in the same spot, wouldn't the sudden transition from the sunlight mean that his eyes would be overwhelmed by darkness?"

"Certainly," he replied.

"Now, the process of adjustment would be quite long this time, and suppose that before his eyes had settled down and while he wasn't seeing well, he had once again to compete against those same old prisoners at identifying those shadows. Would he make a fool of himself? Wouldn't they say that he'd come back from his upward journey with his eyes ruined, and that it wasn't even worth trying to go up there? And would they — if they could — grab hold of anyone who tried to set them free and take them up there and kill him?"

Opinion is the medium between knowledge and ignorance
