Lecture VI

When you go further and consider the feet, you find that whereas the thigh still preserves an intimate connection with the middle man, knee and leg and foot require the support of the earth. The thigh, it is true, uses this support, but the leg and the foot are only there at all because man has to stand firm and upright on the earth. In the thigh we have still to do with a continuation of the middle man. If it were not adapted to the other members of leg and foot, the thigh would, in fact, be able to assume a different form and enable man to be a creature of the air. Quite different organs might then be developed beyond it, appropriate for swimming or flying. These would be set in motion by means of the thigh, but everything else about them would have to be adapted to their purpose.
