I can claim a non superficial knowledge of Nietzsche's works from the Gay Science onward, even letters and fragments, but not really on the writings about Wagner.
I can also label myself as Nietzschean, without needing to make distinctions and caveats. I don't mean that I see Nietzsche's philosophy as absolute truth - that would be so anti-nietzschean - but it is my profound opinion that future philosophy either starts from Nietzsche or it does not start at all.
To use a rough comparison, we have had 25 centuries of philosophy as comments on Plato, and I would predict that we are going to have an equivalent span of time of comments on Nietzsche.
Having said that, the GM is the work I like less and partially share the criticism you refer to.
From an audio lecture series by Patrick Grim, some content from the lecture "A Genealogy of my Morals"
N's Geneology of morals is a deeply flawed book, but useful on at least one account. On the positive side the Genealogy contains a strategy for evaluation of one’s own moral view. The history of our ethical concepts may offer reasons to accept or reject them. They might teach us more than just history, but offer ethical lessons as well about our concepts.
I guess that, as far as N. is concerned, this is not relevant.
Now I haven't done my homework on this and I am not going to argue rigourously using quotes and references, but my view is that his purpose was to prove that the cardinal moral values (of what is generally called Judeo-Christian society) have their origin not from the metaphysical intuition of some otherwordly superior order, but from
ressentiment and lower instincts, herd's instincts and slaves' morality that ultimately - through Christianity - managed to topple the (cultural) hegemony of the
kaloi kai agathoi (the beautif and good people) that ruled the classical world. These are forces against what rised mankind from mud - while usually the contrary is held as true - that depress the force of life and are against it, ultimately leading men to an unworthy living steered to self-annihilation.
The GM is the attempt to present this thesis in a pseudo-scientific fashion and I agree with the objection that in this respect the book has flaws.
Now the abrading:
N’s vocabulary and sensibilities incorporated directly into core concepts of Nazi’s. He was read and re-read by Hitler, and the ideas of GM reverberate throughout Mein Kampf.
N is a 'despicable racist.' There is a small industry in trying to explain his racism, and trying to explain away his link to the Nazi’s and the death camps. No one tries to explain away his sexism.
His Sister is often used a scapegoat, but GM is steeped in anti semitic stereotypes and are essential to the work’s showing the Jewish undercutting of the triumph of the great blonde beast, the aryan ubermensch.
It is possible that «N's vocabulary and sensibilities incorporated directly into core concepts of Nazi’s».
More broadly, it seems pretty reasonable to believe - and it's more than an hypothesis - that Nazis have used N.'s work as a basis for their claim of racial superiority and violent praxis. And this is not limited to GM, there are many other N.'s quotes quite compatible with and seemingly supporting Nazi's ideology.
I could claim that this can be said also of some excerpts from the Gospels or early Christian scholars (and I rather believe that this is where anti-semitism and much contemporary racism is rooted, as well as a certain sense of what is called nowadays "community" stemming from the Germanic ethos), but that would not unmake the criticism directed to Nietzsche.
Acknowledging all this, I do not think it is worthwhile, philosophically speaking, to counter this objection, because:
- It is a rejection based on morality, not on a philosphical argument. (That's definitely the case of Russel and also of Severino - although the latter distinguishes himself also for his lack of honesty. Btw, it is true that there is much ado about showing that N. was absolutely not a (proto-)nazi, that on the contrary he was the saint that he feared he would have been represented as some day... Well, this is the same flawed of argument, only reversed. Anyway, those engaging in this debate, like those maintaining that N. was a psycho, mysoginous and a sociopath, generally show quite a shallow and utterly indirect knowledge of his works).
- Löwith, writing at the time when the Nazis were ruling Germany, rightly observed that, as N. is not a conventional systematic philosopher, single quotes of him could be easily used to support about anything as well as its opposite (and this exercise can be easily made for anti-semitism).
- The argument is a fallacy (many actually, but at least the affirming-the-consequent one).
Moreover, there are facts in N.'s life that lead to infer, beyond any reasonable doubt, that he was definitely far from supporting anti-semitism.
But all this is not to deny that N. used the concept of race and even of superior race. And indeed N. had a negative opinion of women, qua women.
I guess that, as much as one may dislike it, the concept of race has
also a physiological basis. Please note
physiological not
biological.
In his last works, starting from 1886 in the foreword to the second edition of
la Gaya Scienza, N. maintained that there is a physiological basis to philosophy. It is not clearly expressed, at least to my knowledge, but it is possible to argue that only some organisms (I would use the word
kallimachoi, the plural of a Greek name meaning "beautiful fighter" - and Callimachos is also the principal character of a Machiavel's play) can "produce" a philosophy expressing the "supreme biological point of view", a philosophy resulting from the will-to-power affirming, and expanding a flourishing life. For the others, philosophy is the promotion of sick values caused by the misunderstanding of a weak body. (This view can be quite safely supported also making references to
Ecce homo).
Based on this and referring to the first chapter of the
Twilight of the Idols, it seems that N. believed that these physiologically blessed men - as the Athenians - can indeed breed a superior race. Superior inasmuch they would make a superior (that one should understand as meaning mainly "beautiful") form of living possible - not because they have a fair complexion and are blue-eyed.
I could dwell longer on this, but I guess that what said above, including the references made, makes enough for claiming that biology per se is not what makes a race superior. Belonging to some "races" can actually increase the probability of sharing the "good genes", but that would not be enough if separated from other external factors. One is culture. But also climate must be taken into account (see
Ecce homo).
Seemingly, according to Nietzsche, "superiority" is the outcome of a balance between physiological characters and environment, so that ultimately superiority is not exactly inherited, but it can also be build. (Although it seems equally admissible to believe that N. maintains that some are doomed to sickness and mischievous philosophy).
As for women, I do not see a way to make the man politically correct.
Probably for the same reasons that made for the idea of a superior race, women are deemed to be inherently different and their "essence" conveys a negative will-to-power.
One can find ways to soften these claims and/or to justify them on the basis of N.'s personal life (getting right into the pitfall of a debate that is moral and not philosophical), but at the end of the day it is what it is: women are unlike men and can be harmful to them... and personally I really don't feel like confuting this view.
Finally, when discussing these Nietzschean themes, one should also bear in mind that they are shaped in the context of a philosophy denying free will and affirming the eternal recurrence. So, default assumptions about their meaning and consequences should be scrutinized with some care - but I am not going to go any deeper on this, at least for now.
