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.

The body is equipped to perform far better, in a variety of ways, than you give it credit for, however—but the fact remains that the genetic structure focuses volition. The genetic apparatus and the chromosomal messages actually contain far more information than is ever used. That genetic information can, for example, be put together in an infinite number of ways. (Long pause.) The species cares for itself in the event of any possible circumstance, so that the genetic messages also carry an endless number of triggers that will change genetic combinations if this becomes necessary.
