Abstract

In an event ontology such as Whitehead's, where subjectivity is distinguished from objectivity as present immediacy confronting past fact, all events enjoy subjectivity in their own presentness.  There can be no evolutionary emergence of subjectivity, if subjectivity as the capacity for being influenced by novel possibility is a necessary presupposition of emergence.  By the origin of subjectivity we mean rather to investigate the way in which any event can acquire its own initial subjectivity, understood in terms of two components, subjectivity and aim.  I derive the present creativity of an occasion from a pluralization of future creativity.  This future creativity can be identified with God, whose way of unifying experience for the nascent occasion provides the aim, understood in terms of subjective forming rather than in terms of an objective possibility.  A final section discusses the question of the metaphysical origination of subjectivity as it pertains to Hartshorne's philosophy.  [Abstract from The Philosopher's Index]
