Hunger and sex still dominate the primitive mammalian side of human existence, but at the present time it looks as if humanity were within sight of their satisfaction. Permanent plenty, no longer a Utopian dream, awaits the arrival of permanent peace.

It is characteristic of science that the full explanations are often seized in their essence by the percipient scientist long in advance of any possible proof.
