a very great impulse towards the building of the Panama Canal. But there was something else, of even higher importance, and greater dynamic power.

And what is this other, greater impulse? It is the desire of the human male to build a world: not “to build a world for you, dear”; but to build up out of his own self and his own belief and his own effort something wonderful. Not merely something useful. Something wonderful. Even the Panama Canal would never have been built simply to let ships through. It is the pure disinterested craving of the human male to make something wonderful, out of his own head and his own self, and his own soul’s faith and delight, which starts everything going. This is the prime motivity. And the motivity of sex is subsidiary to this: often directly antagonistic.
