Evil is the vulgar lover who loves the body rather than the soul, inasmuch as he is not even stable, because he loves a thing which is in itself unstable, and therefore when the bloom of youth which he was desiring is over, he takes wing and flies away, in spite of all his words and promises; whereas the love of the noble disposition is life-long, for it becomes one with the everlasting.
PlatoOne trait in the philosopher's character we can assume is his love of the knowledge that reveals eternal reality, the realm unaffected by change and decay. He is in love with the whole of that reality, and will not willingly be deprived even of the most insignificant fragment of it - just like the lovers and men of ambition we described earlier on.
