I am not in complete disagrement about your take on N. What corrupt N. ethic was is belief in the Darwinism and atomistic materialism of his era....
But i will not go further about N. here...
But your remark about the "bogus spirit idea" say more about you than anything..
No serious thinker in all human history called the spirit a "bogus idea" save James Randi and Barnum the father of circus which are more comic book persona than thinkers... Than try to "think " a liitle bit more than repeating materialist Richard Dawkins TV mantra interview...
I am sorry to say this in a seemingly rude way, but there is many people here who dont like to be called consumers of "spirit bogus idea" ....
All litterary, philosophical and scientific education point to the "spirit"...If you dont know that go back to school...But not in engineering school for sure....
N’s confused notions of anthropology certainly corrupt much of his moral conceptions (it’s a pretty poor foundation). That said (quite apart from the bogus Spirit idea), his general point as regards proper use of goods, entertainment, etc. can be helpful when finely filtered. In the end, N’s the last guy I’d read on ethics.
