Useful videos here from D. Chalmers:

There isn't that much here that come as a surprise to any of us who have followed his career [read 'in his wake'] over the past 15 years, but it should be useful for any intro class. He is engaging and charismatic as always.

Although I will note that he's speaking much more slowly than when I saw him speak at Princeton back in '98. Either he's been coached by the TV presenters, or we're all getting old.
