Obama's got a great sense of humor, but mainly he has a great thinking presence, which is uncommon. It's hard to imagine being able to do, think over answers and deliver them on television. If I were president I would constantly be spluttering.

Obama's the most thoughtful-sounding president I can remember. He seems to be saying what he wants to say, and that is a great relief. He always sounds like he's thinking about what he's saying while he's saying it, and that's a rare thing in politicians.

It's my belief that sanity lies in realizing that reality is not exactly what we had in mind.

When I weed, I like to get off into my own head. For one thing, my wife plants and I have trouble telling which plants are weeds and which are my favorite plants. So I tend to hop around and grab the weeds that I know are weeds. So I don't weed all that linearly. I tend to weed haphazardly.

Even intellectuals should have learned by now that objective rationality is not the default position of the human mind, much less the bedrock of human affairs.

I do not know what the cat can have eaten. Usually I know exactly what the cat has eaten. Not only have I fed it to the cat, at the cat's insistence, but the cat has thrown it up on the rug, and someone has tracked it all over onto the other rug. I do not know why cats are such habitual vomiters. They do not seem to enjoy it, judging by the sounds they make while they are doing it. It's their nature. A dog is going to bark. A cat is going to vomit.

Studying literature at Harvard is like learning about women at the Mayo Clinic.
