Don't ask me why, but I went to see some live music last night. The opening act was some apparently semi-famous country singer/songwriter type. She performed with an acoustic guitar and some guy on electric. Anyway, her final song of the evening had as its chorus, "What doesn't kill me makes me stronger." As you may know, that's a quote from Nietzsche (from his Twilight of the Idols, I think).
It's always sad to see profound insight appropriated by ignorant hacks for sappy bullshit. But the insult goes deeper: the song was about how guardian angels watch over us and make sure we get stronger.
I'm no fan of Nietzsche as a philosopher (though I'm willing to allow that he is probably not as bad as many of his disciples make him out to be), but I couldn't help but feel sorry for the poor old guy as he was turning in his grave.
