Abstract

Attempts to sanitize psychology's fragmentation will postpone the inevitable task of identifying and conceptualizing the particulars represented by psychological data. Psychological data represent things done, changes brought about by one or more organisms. Things done comprise a vast, densely populated, and always changing domain of events. Things done depend on organisms but are conceivable apart from organisms. The domain of things done contains particulars (i.e., content) and universals (i.e., patterns). Developing a compelling linkage between psychological theory and psychological data will require psychologists to abandon the assumption that the organism is the psychological unit.
