The Age of Fallibility (2006)
Context: The main obstacle to a stable and just world order is the United States. This is a harsh — indeed, for me, painful — thing to say, but unfortunately I am convinced it is true. The United States continues to set the agenda for the world in spite of its loss of influence since 9/11, and the Bush administration is setting the wrong agenda. The Bush agenda is nationalistic: it emphasizes the use of force and ignores global problems whose solution requires international cooperation. The rest of the world dances to the tune the United States is playing, and if that continues too long we are in danger of destroying our civilization. Changing the attitude and policies of the United States remains my top priority.

This is Your Brain on Music (2006)
Context: It is only in the last five hundred years that music has become a spectator activity—the thought of a musical concert in which a class of "experts" performed for an appreciative audience was virtually unkown throughout our history as a species. And it has only been in the last hundred years or so that the ties between musical sound and human movement have been minimized.
