Abstract

Whitehead subscribes to an epochal theory of becoming whereby events take place "all at once", yet he describes this process in terms of earlier and later phases of becoming.  This essay defends and develops an earlier interpretation resolving this apparent conflict ("on genetic successiveness," Southern Journal of Philosophy 7/4 (winter, 1969-70), 421-25) against objections raised by Robert C. Neville and John B. Cobb, Jr.  It introduces a matrix of abstract temporal loci in terms of which genetic and coordinate divisions of the same occasion may be correlated.  Successive genetic phases of an occasion are temporally later than one another, yet cohere in the same present. The becoming and the being of an occasion occupy exactly the same temporal extent, yet differently.  The being inherent in the becoming of an occasion belongs to the many past actualities felt, as these many feelings seek a common unity.
