A moderate eclecticism: ontological and epistemological issues.

The principle of eclecticism is discussed with the point of departure in a definition of psychology and its subject areas. It is argued that eclecticism constitutes one of the key developmental conditions for science. The argument begins with an analysis of the distinction between real and recognized object and concludes that a scientific object always has an infinite number of aspects and that this fact is not reducible to a question of complexity. Next a differentiation between theoretical levels based on ontological arguments are introduced and it is concluded that it is necessary to accept positive eclectic processes in theories, and that development of theories is due to an eclectic relationship with other theories. A series of examples are given for different versions of the eclectic development of psychological disciplines and concepts, namely phenomenology, psychoanalysis, stress, and cognition.
