@Nabokov Both have to be true. If it wasn't for Ray's will to life, which I think of as THE will to life, which he so naively possesses and which he has to so naively possess lest he would not be able to penetrate the question of biology so directly, higher life could not be pursued in the first. Everything else is superfluous. And Ray understood hierarchy, biological hierarchy of bodies of cells and of states of bodies, he understood subordination and cooperation and competition because they are part of the same self-ordering process, whether in the body of an organism or in a nation.
Also, there's a difference between the retard argument of 'genetic determinism', as used by modern medicine, which is fundamentally an anti-Nietzschean denial of the will, and true 'biological determinism', in the sense that all rational thought stems from the BODY and the question of inheritance is as important to an organism as the question of the biological effects of its own environment like how Nietzsche writes about. This is all in accordance to Ray's thought. But the question is whether something exists priori to the will to health. To make yourself healthy, you must already be healthy at the bottom of your nature.
