He had been wont to despise emotions: girls were emotional, girls were weak, emotions—tears—were weakness. But this morning he was thinking that being a great brain in a tower, nothing but a brain, wouldn’t be much fun. No excitement, no dog to love, no joy in the blue sky—no feelings at all. But feelings—feelings are emotions! He was suddenly overwhelmed by the revelation that what makes life worth living is, precisely, the emotions. But, then— this was awful!— maybe girls with their tears and laughter were getting more out of life. Shattering! He checked himself: showing one’s emotions was not the thing: having them was.
