Norman Gulley, a noted scholar of classical philosophy, examines the transition from Socratic inquiry to the more complex metaphysical frameworks found in Plato's later writings. By analyzing the interplay between perception, belief, and knowledge, the author provides a rigorous reconstruction of how Plato addressed the problem of defining truth in a changing world.
