Collected Works Vol. I

Bergmann's early philosophical work concerned the foundations of psychology and physics (topics were e.g. the behaviorist J.B.Watson, operationism, psychoanalysis, psychological measurement, psychophysics, emergence and quantum physics). From the early 1950s he concentrated his research on metaphysics and ontology. He developed an ontological system, at first a rather simple one, that became more and more complicated and sophisticated. It culminated in the posthumously published "New Foundations of Ontology" and his last three papers.
