Butchvarov left Syracuse University in 1968 as a full professor to move to the University of Iowa, where he was at the time of his retirement in 2005 the University of Iowa Foundation Distinguished Professor of Philosophy. He was President of the American Philosophical Association in 1992–93, and has served as editor of the Journal of Philosophical Research. Butchvarov has made major, systematic contributions to contemporary metaphysics, epistemology, and ethics. His books include Resemblance and Identity: An Examination of the Problem of Universals, The Concept of Knowledge, Being Qua Being: A Theory of Identity, Existence and Predication, Skepticism in Ethics, Skepticism about the External World, and Anthropocentrism in Philosophy. Some of his writings can be found on http://myweb.uiowa.edu/butchvar/ and, more reliably, http://butchvarov.yolasite.com/. In metaphysics, Butchvarov is perhaps best known for his work on the identity theory of universals and on the nature of informative identity statements. In epistemology, he argues for the view that knowledge is the absolute impossibility of mistake. In ethics, his central metaethical thesis is that a realist account of goodness is defensible if goodness is seen as a generic property. Butchvarov may be said to have been influenced by philosophers as varied as Plato, Kant, Hegel, and Wittgenstein. The latter's influence can perhaps best be seen in Butchvarov's metaphilosophical Method of Analogy for which he argued in "The Limits of Ontological Analysis", The Ontological Turn: Studies in the Philosophy of Gustav Bergmann ). He claims that understanding is most often a matter of coming to see what something is like, seeing what it literally is being a limiting case, and that it is the noticing, discovery, and grasping of similarities and differences that is the core intellectual achievement in our understanding of the world. In his most recent work, Butchvarov argues that anthropocentrism in philosophy, though common, is deeply paradoxical. Ethics investigates the human good, epistemology investigates human knowledge, and antirealist metaphysics holds that the world depends on our cognitive capacities. But humans' good and knowledge, including their language and concepts, are empirical matters, properly investigated by empirical sciences, not armchair philosophy. And humans are inhabitants, not "makers," of the world. Nevertheless, all three – ethics, epistemology, and antirealist metaphysics – can be reinterpreted as making no reference to humans. Ethics would be confined to the metaphysics of the generic property goodness, epistemology to the appraisal of basic nonformal inferences, and antirealism to the logical structure of the world. Butchvarov's latest papers are "Commonsense Political Philosophy," "Counterfactuals and Antirealism," and "Afterlife," all available at http://butchvarov.yolasite.com.
