David Christensen Author, Translator & Editor

David Christensen is Professor of Philosophy at Brown University. He has written on such questions as: What determines whether a given bit of evidence supports or refutes a given theory? What logical principles apply to rational beliefs (either degrees of belief or all-or-nothing beliefs)? How should our theory of ideal rationality accommodate rational self-doubt-and in particular, to doubts generated by the disagreement of apparent epistemic peers? He is the author of Putting Logic in its Place: Formal Constraints on Rational Belief (2005, Oxford University Press). Jennifer Lackey is Professor of Philosophy at Northwestern University. Her recent research focuses on the epistemology of groups, the epistemology of testimony, norms of assertion, and the epistemic significance of disagreement. She has co-edited (with Ernest Sosa) The Epistemology of Testimony (2006, Oxford University Press) and is the author of Learning from Words: Testimony as a Source of Knowledge (2008, Oxford: Oxford University Press). She has been the recipient of a Charles A. Ryskamp Research Fellowship through the American Council of Learned Societies (2007-2008), as well as a Summer Stipend through the National Endowment for the Humanities. She is also a winner of the Young Epistemologist Prize (2005).
