Abstract

The widespread assumption among academic philosophers that no truth can be simultaneously necessary and factual, founded on the analytic-synthetic dichotomy, was challenged from outside the profession by Ayn Rand and Leonard Peikoff in the 1960s, and from within the profession by Saul Kripke and Hilary Putnam in the 1970s. Gregory M. Browne's book Necessary Factual Truth represents a long-overdue attempt to synthesize the Rand-Peikoff and Kripke-Putnam approaches into an integrated theory. While Browne's project is partially successful, it gives up one of the chief attractions of these approaches: the ability to preserve continuity of reference across radical theoretical change
