Summa Philosophiae: a Semantic Wiki for Professional Philosophers Jean-Baptiste Guillon Coll` ege de France, Paris, France guillonjeanbaptiste@gmail.com Abstract. The resources of the semantic web could be of great use to professional philosophers working in the analytic tradition. Given the highly structured and rapidly evolving nature of the state of the art in analytic discussions, it is argued that a semantic wiki would be the most appropriate tool to represent in a dynamic way the evolution of the state of the art. The massive collaboration of philosophy graduates could generate rapidly a very useful database, open for virtually infinite combinations of intelligent queries. Keywords: Semantic Wiki, Philosophy, Scientific Publishing 1 Introduction: Philosophy on the Web Contemporary analytic philosophy is a discipline which has a functioning very close to that of science: the discussion is structured by the contributions of a large number of collaborators, mostly published as short papers in specialized journals, and intended to make very precise points within a commonly recognized state of the art. Because of its rapidly evolving state of the art, and also its massively collabo- rative nature, it is only natural that analytic philosophy has been using the tools of the web, which allows for massive collaboration and rapid changes. Besides many professional blogs, two websites are already particularly important for the contemporary practice of professional philosophy: the Stanford Encyclopedia of Philosophy, and PhilPapers. The Stanford Encyclopedia of Philosophy [6] is an online encyclopedia run by Stanford University. For every entry, the editorial board of the encyclopedia contacts an expert in the field, who is in charge of writing the entry, and keeping it up to date across time (every two years or so). Hundreds of entries have been written since the creation of the encyclopedia in 1997, which make it one of the best philosophical encyclopedias in history. A second important website is PhilPapers 1 PhilPapers is a comprehensive index of everything that gets published in philosophy (journals, books, papers, etc.). The references are organized in categories according to their field and the specific questions they deal with. This work is done by a large number of area 1 http://philpapers.org/help/about.html 69
