In this radical reinterpretation of Aristotle's "Metaphysics", Walter Wehrle demonstrates that developmental theories of Aristotle are based on a faulty assumption: that the fifth chapter of "Categories" ("Substance") is an early theory of metaphysics that Aristotle later abandoned. The ancient commentators unanimously held that the "Categories" was semantical and not metaphysical, and so there was no conflict between it and the Metaphysics proper. They were right, Wehrle argues: the modern assumption, to the contrary, is based on a mediaeval mistake and is perpetuated by the anti-metaphysical postures of contemporary philosophy. Furthermore, by using the logico-semantical distinction in Aristotle's works, Wehrle shows just how the principal "contradictions" in "Metaphysics" Books VII and VIII can be resolved. The result is an interpretation of Aristotle that challenges mainstream viewpoints, revealing a supreme philosopher in sharp contrast to the developmentalists' version.
Walter Wehrle was professor of philosophy at George Mason University until his death in March of 1996.
