The beaver is not free to make a spider web. (Long pause.) In human beings the genetic structure largely determines physical characteristics such as height, color of eyes, color of hair, color of skin—and, of course, more importantly, the number of fingers and toes, and the other specific physical attributes of your specieshood. So physically, and on his physical attributes alone, a man cannot use his free will to fly like a bird, or to perform physical acts for which the human body is not equipped.

You reason out your position. Otherwise your free will would have no meaning in a physical framework, for the number of choices available would be so multitudinous that you could not make up your mind to act within time. With all the opportunities of creativity, and with your own greater knowledge instantly available, you would be swamped by so many stimuli that you literally could not physically respond, and so your particular kinds of civilization and science and art could not have been accomplished—and regardless of their flaws they are magnificent accomplishments, unique products of the reasoning mind.
