Professor Isaac Levi (1930-2018)
Isaac Levi died on Christmas Day, 2018, just before midnight. For the Philosophy Department at Columbia, where he taught from 1970 till he retired as the John Dewey Professor of Philosophy, this is a loss without measure. Isaac was one of the most creative and most fiercely independent-minded philosophers of the last half century. His contributions to the fields of formal epistemology and decision theory and pragmatism are widely influential and greatly admired. His presence in the department over four decades was vast and forceful during his lifetime and will no doubt abide after his death. A longer notice of his philosophical achievements and his vital influence at Columbia will be published in the January issue of the Journal of Philosophy at which he was an indispensable editorial presence for many years.
