Speech at the National Press Club (2004)
Context: An open society is always in danger. It must constantly reaffirm its principles in order to survive. We are being sorely tested, first by 9/11 and then by President Bush's response.

Context: There is no reason why an extraphysical general principle is necessarily to be avoided, since such principles could conceivably serve as useful working hypotheses.
