The great moment I think in human consciousness is when you realize that the object in front of you is perhaps not nameable or is new, it does not fit a stereotype, and so you need to reconfigure your whole structure of knowledge to account for it.

I know stereotypes have a bad reputation, people say, "Oh, you shouldn't stereotype people," but I think it's important to recognize that we couldn't function in the world without stereotypes.

Obviously invidious and prejudicial stereotypes need to be deconstructed and overcome, but it's not that they can be destroyed. I think that would be an illusion to think that we can somehow get rid of these basic search templates that allow us to sort out our social lives and to sort out the material world as well.

I think it's very important to distinguish between objectivity - which tends to be open, flexible, skeptical of its own certainty and open to new information - and objectivism - which thinks, "No, we know it all, we've got it, so real thinking and learning can come to an end."

Stereotypes, I want to say, have to be thought of not just as these invidious, bad things that we could get rid of, but as images that we cannot get rid of, that we have to live with.

I see stereotypes as fundamental and inescapable and not as something that is... The kind of common view is "Oh, we shouldn't think in stereotypes," and I think the reality is we can't help but think in stereotypes.

When students scoff at the idea of a magical relation between a picture and what it represents, ask them to take a photograph of their mother and cut out the eyes.
