I hadn't seen anything recently by Jim Holt--the philosophy journalist whose byline always says he's working on a book about "the puzzle of existence"--so I Googled him and found him being interviewed at this cool website. Will have a closer look later...when I'm done with the puzzle of painting. Why paint your kid's room a different color? What's the point of color? What is it worth to change it? How much longer can I avoid getting back to work by asking these idle questions?
