Plato Was Right All Along

Alfred North Whitehead memorably described the history of Western philosophy as "a series of footnotes to Plato." Perhaps this is even more apt as a description of the history of Christian philosophy. Christian Platonism is a venerable tradition indeed, with St. Augustine himself as its most distinguished exemplar.

(The argument in favor of this of course rests on the fact that it seems we can express the same proposition in different languages.) Another professor of mine who was auditing the class protested incredulously that this position "amounted to Platonism." A more damning indictment could hardly have been made. Lewy's response was equally revealing: "My dear sir, of course no one wants to be a Platonist. It's like believing in God—a great intellectual sin in the eyes of the academic ...
