How Plato’s Theory of Truth Explains the Socratic Method. Consistency is the Test of Truth

Author: Jenks, Rod
This book argues that Plato’s Socrates subscribes to a coherence theory of truth, and according to that theory, there is only one fully consistent set of beliefs: the set which contains all and only true members. Thus, not only does inconsistency between two beliefs indicate that at least one of them is false, but the consistency of a belief with the other beliefs in the system suffices for its truth.


“In “The Socratic Elenchos,” perhaps the most often cited and most controversial paper about the Socrates written in the 20th Century, Gregory Vlastos articulated and tried to solve what he called “the problem of the elenchos.” . . . In this book. Jenks develops his own, very novel and logically rigorous answer to the problem first framed by Viastos. Jenks argues for the claim that the Socratic method of argument is based upon a coherence theory of truth.” – Prof. Nicholas D. Smith, University of Portland
