“but only a mystic would have said: "Every beast is driven to the pasture with blows"; and again: "It is hard to fight with one's heart's desire. Whatever it wishes to get, it purchases at the cost of soul"; and again: "Wisdom is one thing. It is to know the thought by which all things are steered through all things." [1] Examples might be multiplied, but those that have been given are enough to show the character of the man: the facts of science, as they appeared to him, fed the [4] flame in his soul, and in its light he saw into the depths of the world by the reflection of his own dancing swiftly penetrating fire.” source
