Research and Professional Activities
My current research focuses on the various theories of justification -- foundationalism, coherentism and infinitism. The latter view, namely that the structure of justificatory reasons is infinite and non-repeating, has never been carefully investigated primarily because it was thought that there are obvious, sound objections to it. I do not think those objections are sound. Further, I think there are some unanswerable objections to foundationalism and coherentism. The task is to uncover the advantages and drawbacks of infinitism.
