“Much was possible to a man in solitude; perhaps the final transmutations and achievements in the zones on the yonder side of the central Knowledge were possible only to the spirit in solitude. But some things were possible only to a man in companionship, and of these the most important was balance. No mind was so good that it did not need another mind to counter and equal it, and to save it from conceit and blindness and bigotry and folly. Only in such a balance could humility be found, humility which was a lucid speed to welcome lucidity whenever and wherever it presented itself.”
