In my travels, I met a man who presented me with strong evidence to suggest that he knew, as he claimed, 99.8% of everything. We walked in the same direction for many days, and after I had asked him the hardest questions I knew (to test him) and the hardest questions I wanted to know (because I then believed him), I asked him what he wanted most. I half-expected he would give some lame answer such as, 'That's part of the .2% I don't know,' but was relieved to find that this was not his answer. Instead, he stopped walking and fixed me with a steady gaze.
