“He is a seemingly arbitrary man, this is because he knows what he is talking about better than any one else. He is a philosopher and a metaphysician, and one of the most advanced scientist of his day, and he has, I believe an absolutely open mind. This, with an iron nerve, a temper of ice-brook, and indomitable resolution, self-command, and toleration exalted from virtues to blessings, and the kindliest and truest heart that beats, these form his equipment for the noble work that he is doing for mankind, work both in theory and practice, for his views are as wide as his all-embracing sympathy.”
