Hi,
I am very interested in philosophy and have realized through the years that tenents of ancient philosophy I discovered some 40 years ago are as valid today as then in instructing one on "intelligently" perceiving and reacting to one's environment and circumstances. Sadly, I have not found the time to keep abreast of modern philosophical ideas (most of my time being spent working, rearing a family and studying religion and the Bible, in particular) and am unfamiliar with the works of philosophers Giovanna Borradori and Jürgen Habermas and Jacques Derrida, the two men she interviewed for "Philosophy in a Time of Terror." Upon reading a synopsis of the work, however, I note a similar theme of philosophy, as I understand such, and these dialogues/essays (dialogues being a favorite method of philosophers to elucidate their "points") in that they use their own "systems" of philosophy to pose a reasonable response to the horrors of 9/ll. (see http://www.sens-public.org/spip.php?article102) Unfortunately, my unfamiliarity with their ideas and postulates prevents my providing a cogent, expansive answer to your question. If you have read "Philosophy in a Time of Terror" (which I have not) and are knowledgeable about philosophical principles in general, you can probably answer this question better than I. If you do form your own conclusions and fashion an answer, I would very much like to read it.
