Well, in WP 550, which I quoted in full a couple of pages back, Nietzsche seems to suggest the doctrine of the will to power in not so many words, using the word “intention” instead of the phrase “will to power”. And “intention” is Absicht in the German, which derives from the verb absehen in its use of es auf etwas abgesehen haben, “to be out for something” with the added sense of “to be on the lookout for something”.
However, elsewhere (can’t tell you where exactly, as I’m at work; I’m pretty sure it’s on several occasions), Nietzsche criticises Schopenhauer for musing about the will without a “to”. For Schopenhauer, it seems, it was just blind will. Nietzsche, on the other hand, seems to merge will and representation (as Martha Nussbaum points out, this can even be seen in the BT already, where Nietzsche characterises the Apollonian as well as the Dionysian as a drive): compare BGE 19 (which is one of the passages I was thinking of before, I realise now), where Nietzsche says that “in every willing, there is […] the feeling of the state towards which” and “the feeling of this […] ‘towards’ itself” (among other feelings); and not just feelings, but also thinking.
Other than that, yes.
I have a German edition lying around somewhere if you want. Also, Lampert’s new book has just come out, and it’s in large part about Nietzsche’s relation to Schopenhauer and Wagner.
