Humanities Distinguished Professor in Philosophy, Adjunct Professor of Cognitive Science, and Distinguished University Scholar at The Ohio State University, Columbus. His took his Ph.D. in logic, and his B.A in mathematics and philosophy at the University of Cambridge. He also holds a Diplom from the Goethe Institut. He is a Fellow of the Academy of Humanities of Australia, an Overseas Fellow of Churchill College, Cambridge, and an Associate of the Center for Philosophy of Science at the University of Pittsburgh. He has strongly interdisciplinary interests. He has held fellowships from both the Alexander von Humboldt Foundation (for work in philosophy of biology) and the National Endowment for the Humanities (for work on rational belief revision). His research has also been funded by the British Academy (for work in philosophy of biology) and by the Australian Research Council (for work on computational logic). He is an ex-President of the Australasian Association of Philosophy and has served as editor of the American Philosophical Quarterly. His research interests include logic (philosophical, mathematical and computational), philosophy of mathematics, philosophy of science (especially biology) and philosophy of language. His books include Natural Logic and Autologic (both with Edinburgh University Press), Anti-Realism and Logic and The Taming of The True (both with Oxford University Press), and Philosophy, Evolution and Human Nature (Routledge and Kegan Paul, co-authored with the behavioral geneticist Florian Schilcher). Tennant has authored numerous publications in scholarly journals, applying both logical methods and scientific theory to various philosophical problems. His contributions include his constructive and relevant system of core logic; a naturalizing, evolutionarily informed account of human nature; application of proof-theoretic methods to problems in the philosophy of logic and in automated deduction; extension of the methods of natural deduction to provide a logicist foundation for arithmetic; his anti-realist treatment of the problem of truth and knowability; and his computationally implementable account of rational belief-revision.
