“The safest general characterization of the European philosophical tradition is that it consists of a series of footnotes to Plato.”
Alfred North Whitehead, Process and Reality (Free Press, 1969) p. 53.

Taylor Marshall is the Adjunct Instructor in Philosophy at the University of Dallas. 
Aristotle called the philosophy of being "first philosophy" because it does not examine the parts of reality (politics, math, music, history), but reality itself: existence, change, properties, space, time, causality, and possibility. This first philosophy is also called "metaphysics," deriving from the Greek words meta ("beyond") and physica ("physical").
I designed this site for students taking the Philosophy of Being section at the University of Dallas. Whether or not you are taking the course, I hope that you find the articles, outlines, and essays helpful.
Metaphysically,
Taylor Marshall
Pre 1930’s this may have been arguable. Post 1930’s, I wonder.
Surely he should have seen this from his mathematics. With the collapse of Hilbert’s dream to reason out the universe he should have realised that others have tried to pick up the philosophical pieces. They have seen that there are issues far beyond Plato’s analysis.
Personally, I think Plato got it wrong in assuming the law of non contradiction. To blindly assume it (or see it as an axiom ) leaves a shaky credibility.
A person created in God’s image, with the ability to know what God reveals, is in a critically different position. Then, and only then, is the Law of Non Contradiction given its proper place.
