It is the mark of little men to like only what they know; one step beyond, and they feel the black cold of chaos. - Mary Renault

Plato, in his opinion, had committed too much to love.

It is better to believe in men too rashly, and regret, than believe too meanly. Men could be more than they are, if they would try for it. He has shown them that. How many have tried, because of him? Not only those I have seen; there will be men to come. Those who look in mankind only for their own littleness, and make them believe in that, kill more than he ever will in all his wars.

I don't know what more there is to say, except this: that since one can't refuse to know oneself, and it must have happened eventually, I would rather it was through you than anyone else.
