Special Issue: The Logical Alien



Co-edited by Marcos Silva (UFPE/CNPq) & Luiz H. Santos (PUC-Rio)

The truth of our thoughts is traditionally related to their correspondence with reality, to the way the world really is. Logical laws can be thought of as the framework in which questions about truth or falsehood can be asked, as universally valid principles to our thought. Under this perspective, it seems impossible to think while disagreeing with these principles because what counts as a thought is articulated by these same laws. . In his article “The Search for Logically Alien Thought” (Philosophical Topics v. 20, n. 1, 1991), James Conant investigates Wittgensteinian ideas on the question of the possibility of illogical thought, exploring its sources in other authors like Descartes, Kant, Frege, Wittgenstein, in a dialogue with Hilary Putnam’s stance about the matter. The book The Logical Alien: Conant and his Critics (Harvard University Press, 2020), organized by Sofia Miguens (U.Porto), features contributions on various aspects of Ludwig Wittgenstein’s philosophy, inspired by James Conant’s article.


Our special issue proposal is motivated by philosophical discussions on Sofia Miguens’s book. Her book is centrally concerned with the question about the possibility of illogical thought. Major topics on part one of Miguens’s book were discussed in the Logical Alien Webinar, organized in partnership by researchers of the Pontifical Catholic University of Rio de Janeiro (PUC-Rio), Federal University of Pernambuco (UFPE) and Universidade do Porto (U.Porto) during the second half of 2020. Every meeting of this event brought a critical assessment made by a researcher on one of the chapters of the book, covering a stimulating variety of philosophical issues.


The idea of gathering written contributions in the form of papers to be published in a special issue arose naturally among the participants of the webinar. Our special issue will be a venue to deepen this logical and philosophical exploration.
