Major inspiration for my ecology projects came from Malcolm Bull's essay “Where Is the Anti-Nietzsche?” which you will find in a New Left Review for 2000 (May–June).
Bull argues brilliantly that all attempts to climb over or reverse Nietzsche result in falling into his trap, since you are trying to master him.
What is required instead is an aikido-like move in which we crawl out weakly and lamely from underneath Nietzsche, like Danny in the Shining or small rodents surviving the cataclysm that wiped out the dinosaurs. Stop trying to win.
Bull relates this strategic weakness to ecology and identification with other lifeforms. I argue that the ecological age we are now in is an age of weakness, lameness and hypocrisy. And I mean those very precisely and positively.
Anti-Nietzscheanism is, in short, ecological awareness. It's a genius argument and it's not surprising that he liked The Ecological Thought. I have yet to read his book based on the essay, which he sent me subsequently, but I'm about to.
