More than an anthology of philosophical writings, Basic Problems of Philosophy seeks to enlighten the beginner, to clarify his understanding, and to stimulate thoughtful discussion. In our fourth edition, we have again balanced classical with contemporary material, grouping the selections around the major areas in philosophy, Among the new selections you will find Plato's Euthyphro, Aristotle on Tragedy, Kant's Perpetual Peace, and Gilson's What is Christian Philosophy? The views of Ludwig Wittgenstein are presented by Friedrich Waismann: Martin Luther King, Louis Waldman and Isaiah Berlin discuss relevant political issues: R. B. Perry analyzes the relation of art to morality: Morris Ginsbert discusses the psychoanalytic approach to ethics.
