Abstract
Whitehead calls for an extrication of the concept of nature from models of the body/subject, which is always engaged in a process of “extensive abstraction” or simplification, issuing forth our conceptions of serial time and divisible space. The incorporation of serial time into process (thereby unifying the sciences with philosophy) is commonly held to be a key distinction between Whitehead and the more “dualistic” thought of Henri Bergson. This essay examines the affinities between the two thinkers, with particular reference to their common espousal of the primacy of process and a fragmentation of the Kantian unity of subjectivity.
