I've read Plato's dialogues on Socrates and I would like to get into Nietzsche. Obviously, start with the Greeks. I read a while ago that one should read Plato before delving into Nietzsche. Am I ready for Nietzsche? And where to begin with Nietzsche?
Yeah - go for it. To be 'completely' read for Nietzsche, you might have to have read:
John Stewart Mill
But I recommend getting Kaufmans 'Portable Nietzsche' & going from there.
Read the SEP articles of his influences, then read the SEP article on him.
Then read Geneaology.
Of course if you read his precursors more fully, you'd get more out of him -- but you can always read a guy more than once (plus it's more fun that way).
Once you've read a good bit of Nietzsche, read Deleuze's book on him.
Aristotle (Politics and Ethics)
If you want context for Nietzsche, Epicurus might be helpful and should be easy enough to read.
>read Deleuze's book on him.
Bataille wrote a book on him as well, though it isn't very accessible.
Just read him already. Stick with kaufmann or Hollingdale. Someone already mentioned the portable nietzsche from kaufman, you could combine that with basic writing of nietzsche, which is also a Kaufmann translation and have nearly all of his works in 2 books
