I did a JTF search for Nietzsche. Some JTFers view him as a proto-Nazi. I disagree with that view.
According to a Stanford source, "Nietzsche takes strikingly different attitudes toward the Tanach, which he respected, and the New Testament, which he detested. He believed the New Testament didn't improve upon the Old or show any progress."
Consider the following quotes:
"In the Jewish "Tanach," the book of divine justice, there are men, things, and speeches of such impressive style that the world of Greek and Indian literature has nothing to place beside them."
- Beyond Good and Evil, Part III, Aphorism 52.
"The Tanach—now, that's something quite different. All honour to the Tanach! In that I find great men, a heroic landscape and something of the rarest of all elements on earth, the incomparable naïveté of the strong heart. Even more—I find a people."
- On the Genealogy of Morals, Third Essay, section 22.
It was Nietzsche who helped me leave Christianity and it was his preference for the Tanach which helped bring me to Judaism.
