"Ellie said, "Isn't it a little warm for black?"

You're extremely pretty, Dr. Sattler," he said. "I could look at your legs all day. But no, as a matter of fact, black is an excellent color for heat. If you remember your black-body radiation, black is actually best in heat. Efficient radiation. In any case, I wear only two colors, black and gray."

Ellie was staring at him, her mouth open. "These colors are appropriate for any occasion," Malcolm continued, and they go well together, should I mistakenly put on a pair of gray socks with my black trousers."

But don't you find it boring to wear only two colors?"

Not at all. I find it liberating. I believe my life has value, and I don't want to waste it thinking about clothing," Malcolm said. "I don't want to think about what I will wear in the morning. Truly, can you imagine anything more boring than fashion? Professional sports, perhaps. Grown men swatting little balls, while the rest of the world pays money to applaud. But, on the whole, I find fashion even more tedious than sports."

Dr. Malcolm," Hammond explained, "is a man of strong opinions."

And mad as a hatter," Malcolm said cheerfully. "But you must admit, these are nontrivial issues. We live in a world of frightful givens. It is given that you will behave like this, given that you will care about that. No one thinks about the givens. Isn't it amazing? In the information society, nobody thinks. We expected to banish paper, but we actually banished thought.
