Abstract
In speaking of transcendental philosophy here, I mean philosophy as a procedurally rigorous, systematic, and deductive instrument for the general and specific founding of science. I thereby presuppose that transcendental philosophy is not only possible but also is already established, at least in its general fundamentals. Its relevance to the empirical science of psychology can readily be conceived: transcendental philosophy should provide, in a rigorous, systematic, and deductive fashion, an a priori conceptual basis specific to psychology. This conceptual basis should include the theoretical and practical heuristic principles necessary for meaningful research into the relevant area of reality, as well as for the sensible use of the resulting knowledge in general social praxis.
