If there were no internal propensity to unite, even at a prodigiously rudimentary level-indeed in the molecule itself - it would be physically impossible for love to appear higher up, with us, in "hominized'' form. . . . Driven by the forces of love, the fragments of the world seek each other so that the world may come into being.
