Against this doctrine it may be argued that it is not through any fault of the legs that they have to bear the weight of the body, nor was it because the head had done better in the past that it was made the crown of the whole form. The world is the embodiment of one Being, one God. The explanation of this can be found in what a Persian dervish once said, "Man lives in the joy of his belief in God, not knowing whether He is his friend or foe. It is as if when the ocean makes its waves leap up joyfully, a twig floating upon them thinks that it is for it alone that the ocean has caused the rising and falling."
