He is a devout Christian, who believes that Jesus performed miracles, died for our sins and rose from the dead. Take Francis Collins, a geneticist who directs the National Institutes of Health. Some people confuse agnosticism (not knowing) with apathy (not caring). We can, and should, decide that no answers are good enough. We think we need to believe something, but actually we don’t. We settle on answers for bad reasons, for example, because our parents, priests or professors believe it. But when it comes to answers to big mysteries, most of us aren’t picky enough. That’s the lesson I gleaned from Gallagher. There is such a thing as being too picky, especially when it comes to things like work, love and nourishment (even the pickiest eater has to eat something). I haven’t spoken to Gallagher in decades. He also disparaged his friends’ choices, so much so that he alienated us. But he was so critical, so picky, that he never settled on a career. He experimented, dabbling in neuroscience, law, philosophy and other fields.


In my 20s, I had a friend who was brilliant, charming, Ivy-educated and rich, heir to a family fortune.
