He wrote such entertaining books, one can hardly grasp his Germanity, yet there it is. I just breezed through What Nietzsche Really Said and can't resist making a comment or two on this fine and very accessible introduction to his writings. Everyone loves Nietzsche, partly because he wasn't particularly hung up on consistency so over the course of his many books he said just about everything. And for the most part he reads so well after a century--compare the zest and freshness of Nietzsche with your average stuffy Victorian narrative. Ignored in his own day, he is now claimed by every philosophical school.
I'll just offer a couple comments on Chapter 7, "Nietzsche's Affirmative Philosophy." He was life affirming, evident in his admiration for Dionysian passion in art and drama and in his mantra amor fati, love fate. Think movies: Darth Vader's "Luke, embrace your destiny" and Elrond's challenge to Aragorn, "Become the man you were born to be!" are restatements of Nietzsche's position. His misunderstood doctrine of eternal recurrence is simply a way to lend weight and gravity to this life, devaluing both nostalgia and a focus on the next life as the locus of happiness. If you're not fulfilling your life purpose or finding your bliss or being all that you can be right now, in the eternal present, nothing else will compensate.
If not an analytical philosopher, he was without doubt the premier psychological philosopher. After Nietzsche's incisive analysis of ressentiment and the will to power, morality has never been the same. Even his moral relativity or perspectivism itself was double-edged: He critiqued not only the superficial morality he saw around him but also emerging scientism as a potential new form of dogmatism. Sure enough, many today see science as the sole source of knowledge and as eclipsing any need for spirituality or values. Nietzsche championed both, although not in their familiar European Christian forms. He was post-Christian before it was fashionable. And here we are, living dangerously, with our cities built on the slopes of Vesuvius.
