I recently read _Dreams from My Father_ by Barack Obama. A remarkable example of hybrid vigor. I downloaded his family tree & used it for a bookmark.

I am now working on _What Have You Changed Your Mind About?_ (John Brockman, Ed.), which I bought because I have not changed my mind about anything recently. 1- to 3-p. snippets by "150 high-powered thinkers" (it says). Some of them, IMO, have changed in the wrong direction.
