This thesis is an examination of Alfred North Whitehead's epochal theory of time. Two necessary conditions for Whitehead's epochal theory are analyzed. First, Whitehead's requirement that events "become" is examined, with the result that becoming is found not to be an objective, physical feature of events in Whitehead's theory as is commonly thought. Second, the requirement that events be discrete is examined, with the result that this requirement is found to be incompatible with contemporary quantum theory, contrary to Whitehead's claim (...) that it is compatible.
