A bilingual conference (English/French) on “Skepticism and Enlightenment” will be held in 2009-2010 at the University of São Judas Tadeu in São Paulo (December 2-4, 2009) and at the Montréal's campus of the University of Sherbrooke (April 14-16, 2010). The first part at São Paulo is devoted to "Skepticism in the Enlightenment from Bayle to the Encyclopédie" and the second part in Montréal to "Skepticism in the Enlightenment from the Encyclopédie to the German Idealism". If there is already a list of invited papers, some space is available for uninvited papers, in particular for Ph. D. students and post-doctoral students. All propositions (title and abstract) have to be send before August 1st, 2009 and will be submitted to a panel of three readers who will select the best ones. For more information, do not hesitate to contact Plinio Junqueira Smith (email@example.com) and/or Sébastien Charles (Sebastien.Charles@USherbrooke.ca).
