Relativism, although it contains several variants, can be succinctly defined as the viewpoint that no objective standards of good and bad, right and wrong, can be discovered by mankind, and that, furthermore, no objective knowledge of the world is available to us either. This paper explores the validity of relativism by looking at at the Philosopher's Protagoras' definition as well as his beliefs on the topic. Plato's views are also discussed on this topic. 4 pgs. 2 f/c. 1b.
