- BA(Hons) McM
- PhD Indiana
Ed received his BA (Hons) from McMaster University and his PhD from Indiana University. He held a Social Science and Humanities Research Council of Canada postdoctoral fellowship at the Automated Reasoning Project at The Australian National University and taught at Dalhousie Univesity and University of Victoria before coming to Victoria University.
Ed's main research areas are logic and the philosophy of logic. His main interest over the past decade is in developing and finding a philosophically satisfying interpretation of relevant logic. The fruits of his labours in this area can be found in his book, Relevant Logic: A Philosophical Interpretation (Cambridge University Press, 2004). The central idea behind relevant logic is that there needs to be a tighter connection in arguments considered valid than we find in many arguments that are deemed valid by standard (or 'classical') logic. For a brief and relatively non-technical introduction to relevant logic, see Ed's entry on it in the Stanford Encyclopedia of Philosophy.
Ed is also working on projects in paraconsistent logic. Paraconsistent logics are logical systems that do not allow the derivation of every formula from every contradiction. These logics are useful in formalising theories of how people do or should reason about fictional stories, scientific theories, and their own beliefs.
From time to time, Ed returns to the engrossing but very difficult field of the philosophy of probability. His recent paper 'Belief Revision, Probabilism, and Logic Choice' combines his interests in logic with his interests in probability. He is also extremely interested in the problem of the interpretation of probability statements as they are found in scientific theories such as quantum mechanics, but he has made little headway on this.
