I. In “Whitehead’s Theory of Becoming," V.C. Chappell asserts that Whitehead’s “epochal theory of time or becoming is both untenable and unnecessary”. It is untenable, he argues, because “ … the theory itself is unintelligible, and … … the Zenonian argument on which the theory is founded, even in its amended, Whiteheadian version, is invalid”. Although it is not clear to me that Whitehead’s use of Zeno’s arguments is unsound, our concern here will be limited to the first of these (...) two claims. I will attempt to show that Chappell’s demonstration of the unintelligibility of Whitehead’s theory begs the question. His purpose is to present us with a reductio ad absurdum of the epochal theory of time, but he succeeds only in demonstrating that if we substitute other premises for Whitehead’s own, his conclusions will not be consistent with these substitute premises.
