And so he learned to read. From then on his progress was rapid. - Edgar Rice Burroughs

As the body rolled to the ground Tarzan of the Apes placed his foot upon the neck of his lifelong enemy and, raising his eyes to the full moon, threw back his fierce young head and voiced the wild and terrible cry of his people.

Tarzan was an interested spectator. His desire to kill burned fiercely in his wild breast, but his desire to learn was even greater. He would follow this savage creature for a while and know from whence he came. He could kill him at his leisure later, when the bow and deadly arrows were laid aside.

Thus Bradley reasoned—thus most of us reason; not by what might be possible; but by what has fallen within the range of our experience.
