A number of replies to my posting have suggested that I failed to note that Descartes axioms are at fault. My point was precisely that Descartes conclusions are an artifact of the logic he was assuming. If you truly assume that nothing is certain then you clearly have no right to exclude your logical axioms from that hypothesis. I believe that faulting Descartes for this is not entirely fair. Afterall, he invented the search for doubt and certainty didn't benefit from all the doubts we have had since (including my doubts about this SIG!) Edouard Lagache School of Education U.C.
