Vincent Van Gogh

It looks, my dear Glaucon, as if that is where the whole danger lies for a man. It is why the greatest care must be directed toward having each and every one of us disregard all other branches of study, and be a follower and student of this branch of ours, in the hope that he can learn and discover who it is who will give him the ability and knowledge to distinguish the good life from the bad, and choose always and everywhere, out of all those possible, the life which is better. He must take into consideration all the things we have talked about here today, comparing them with one another and choosing between them in terms of excellence of life.
