Elisabeth was an interesting personality. She was different from her brother, and in some respects she embodied his philosophy better than he himself did. For Friedrich was averse to conflict, which his philosophy painted with heroic tones, while Elisabeth , as shown in the Lou affair and the way she managed the Nietzsche-Archiv, was just the opposite: she loved a "gay, fresh, holy war" as she wrote in a letter to her brother (not contained in this book).
The author paints this portrait of Elisabeth well, that of a person who does not succumb to pain as her brother did, but who is, instead, moved by anger. Despite a matronly exterior, and a certain vulgarity of character, there is something heroic in Elisabeth , a kind of heroism different from that of her brother: he sacrificed a good life and friendship for knowledge; she sacrificed friendship and knowledge for a good life.
I have a few problems with the book, starting with the ideological bias of the author, who's a feminist scholar. She demonstrates that Elisabeth was a girl of artistic and literary gift. On this basis, she tries to argue that an education more rigorous than that which Germany provided to girls of that time could have fully developed Elisabeth's talents and guided her on a different path from the one she took in her late 30s, when she joined the anti-Semitic movement, and later in life, with the rise of the Nazis.
However, much of the German intelligentsia of the late 19th and early 20th centuries was anti-Semitic. Why would a good education have protected Elisabeth from such feelings if that was not the case with so many other people of the day?
In addition, the author herself proves that Elisabeth's anti-Semitism was skin deep. Despite being a solid conservative, her attitude toward the Jews was malleable and pragmatic: unfriendly when she was part of Wagner's circle and later married an anti-Semitic activist from that milieu, but sympathetic after she founded the Nietzsche-Archiv, when the friendship of rich Jews who loved Nietzsche was of value to her.
After the rise of the Nazi party, she worked hard through a biased selection of Nietzsche's texts to demonstrate how his work could serve as a philosophical basis for German ultra-nationalism, but she never attempted to portray her brother as hostile to the Jews.
A good education can sometimes protect from wrong beliefs, but not from opportunism, which was the true flaw of Elisabeth's character.
Moreover, it should be noted that, however great Elisabeth's natural gifts may have been, she never showed much love for learning, as many women of the day did.
Another problem I have with the author's approach is the way she treats the Lou affair: Nietzsche was a fool in love; Elisabeth, a jealous liar; and Lou, a girl of enormous genius who left a trail of broken male hearts wherever she went.
As Rudolph Binion's Lou biography shows, the picture is much more complex than that. Lou von Salomé lied about Nietzsche's marriage proposals to her, and also about how their friendship came to end: he broke it, not she as Lou said later. Moreover, much of what Elisabeth told Nietzsche about Lou and Paul Rée's conduct was true, and she unmasked some of Lou's tales already in the biography she wrote about her brother in the 1900s.
That Lou, a free spirit, is generally an easier figure to sympathize with than Elisabeth, a (as the author puts it) "provincial bigot" who later made common cause with the European far right, is no excuse to produce such a one-sided portrait of both these women: of the former as a larger-than-life heroine who only did harm accidentally, and of the latter as a narrow-minded mental dwarf whose petty feelings got the best of her.
The end of the book has as an appendix a little novel written by Elisabeth. Now, the writing itself is not the fruit of some great originality and the characters and their feelings are all petty-bourgeois. However, as Diethe says, it was not a bad choice on Elisabeth's part to use the life she knew as material.
In addition, the novella has some virtues, starting with psychological sophistication, and contains many sly and shrewd observations. My favorite is when the narrator says that nothing displeases the philosopher more than to apply his theories to his immediate reality, as the theory is never quite right when tested against individual people and facts. Despite the fact that, when she was managing the Nietzsche-Archiv, Elisabeth presented herself to the reading public as her brother's first disciple in all senses, it is possible that she did not have a very high opinion either of her brother's thought or of philosophy in general, at least when she wrote the story.
What appears of Elisabeth's personality in the text, is also interesting. To begin with, although she was such a conservative woman, she seems to have had doubts about the traditional expectations that German society imposed on women. The main character of the story, Nora, who undoubtedly represents Elisabeth herself, avoids with contemplative stubbornness the fate that her nagging mother wants to impose on her, that of marrying a good man as soon as possible.
Nora, as a 30-year-old woman, is already past her prime according to the judgments of the time, and so she is the target of both her mother's tirades and the condescension of the matrons of the local society, who gossip about her. Surely that says something of Elisabeth's state of mind and how she perceived her standing in society, for she must have composed this story shortly after the Lou affair, when she was already in the mid-30s (therefore even older than Nora) and still single.
As much as she loves to study, Nora, however, does not shun the domestic life. She cohabits with her brother and provides for the needs of the home, which seems to be a source of great contentment to her. The whole story shows this bias: the happiest homes are those headed, not by husband and wife - whose life is marked more by conflict and incompatibility - but by brother and sister, who form a large number of the households in the novella, all full of complicity and familiarity between the "couple".
It is true that the main couple of the story, Georg and Nora, are not siblings. But Georg, a philologist-turned-philosopher, obviously represents Nietzsche, and Nora, as said before, represents Elisabeth herself. So, even here it is the love between brother and sister that which Elisabeth's little écrit celebrates.
Elisabeth and Nietzsche's relationship has been the subject of incestuous rumors for decades (see the literary hoax "My sister and I"). It is, however, very unlikely that this love was conscious on Elisabeth's part - or, for that matter, requited on Nietzsche's. But the novella indicates that there is a kernel of truth to the story.
As Diethe says, this feeling no doubt gave Elisabeth the impetus to dedicate herself to the Nietzsche-Archiv throughout the second half of her long life, especially as brother and sister were at such different points (ideologically and geographically) when Nietzsche's sanity expired its last breath.
