“His brain worked in dim ways. Yet his conclusions were as sharp and distinct as those achieved by men. He had a method of accepting things, without questioning the why and wherefore. In reality, this was the act of classification. He was never disturbed over why a thing happened. How it happened was sufficient for him.
Thus, when he had bumped his nose on the back-wall a few times, he accepted that he would not disappear into walls. In the same way he accepted that his father could disappear into walls. But he was not in the least disturbed by desire to find out the reason for the difference between his father and himself.”
