phrase to play the video from that point. Just a few minutes ago, I took this picture about 10 blocks from here. This is the Grand Cafe here in Oxford. I took this picture because this turns out to be the first coffeehouse to open in England in 1650. Thats its great claim to fame. And I wanted to show it to you, not because I want to give you the kind of Starbucks tour of historic England, but rather because the English coffeehouse was crucial to the development and spread of one of the great intellectual flowerings of the last 500 years, what we now call the Enlightenment.

But the other thing that makes the coffeehouse important is the architecture of the space. It was a space where people would get together from different backgrounds, different fields of expertise, and share. It was a space, as Matt Ridley talked about, where ideas could have sex. This w
