For a companion, I require one who will make an equal demand on me with my own genius. Such a one will always be rightly tolerant.It is suicide, and corrupts good manners, to welcome any less than this. I value and trust those who love and praise my aspiration rather than my performance. If you would not stop to look at me, but look whither I am looking, and farther, then my education could not dispense with your company.
