“For believe me: the secret for harvesting from existence the greatest fruitfulness and the greatest enjoyment is—to live dangerously!” —Nietzsche, The Gay Science (section 283)
“—Christianity, alcohol, the two great means of corruption.”
The Portable Nietzsche, page 652
“Every kind of faith is itself an expression of self-abnegation, of self-alienation.”
The Portable Nietzsche, page 639
The analogy of Christianity to alcohol is interesting to me. The chemistry of alcohol: ethanol is a carbohydrate, the metabolism of which leads to the inhibition of the enzyme phosphofructokinase (slowing and directing cell metabolism to store instead of burn fat) and is converted to triglycerides in the liver (storing more fat); ethanol binds to the GABA-A receptor which increases effects of the inhibitory neurotransmitter GABA (effectively slowing nervous system reactions), and of course increases liver cirrhosis. (A bit oversimplified, and disregarding the hormetic effect of alcohol, but the point remains.)
The chemistry of Christianity: faith rests on convictions, convictions inhibit the believer from independence so that he “cannot posit himself as an end” and in fact requires someone else—a priest or deity—to posit any end at all, and so he becomes a means to others’ end—a slave—in which case his freedom and sense of self continually deteriorate. Just like alcohol, this pathway dulls the senses and robs men of the vivid sense of life that accompanies self-overcoming or self-actualization.
I’m not sure how much Nietzsche knew about biochemistry, but in any case he has here a deeply accurate analogy.
