Director, The Abductive Systems Group. Errors of reasoning: naturalizing the logic of inference. Models, distortion and paradigm-creep: getting the best out of falsity. A phantom-quantificatier semantics for fiction. Neuro-fuzzy argumentation networks. Aristotle’s early logic.For most of its 2400-year life, logic has been a humanities discipline. From the late 19th century onwards, logic has become a mathematical discipline, and more recently is in process of being absorbed by computer science. One of my central purposes is to investigate and, where possible promote, a grand reconciliation in logic, one in which its mathematical and computational powers would be retained and its relevance for the reasoning of actual people in the circumstances of real life be regained. Over the years, I have been drawn to two of philosophy’s oldest problems. One is how is it possible for beings like us to bear relations of any kind to nothing whatever? The other is, given the constant possibility of error, how is it possible for beings like us to achieve knowledge of the world. My goal is to help chart solutions for these problems by marshalling the resources of a humanized reconciliation in logic.
