Psychology has sought a single, objective base from which to develop scientifically. Such a base is impossible, as there can be no privileged observation methods providing unquestionable facts. There are only real observation tools which can be used to observe other real things. Observations depend upon both the nature of the tools employed and the nature of the things so observed. As the subject ... [Show full abstract] matter of psychology is primarily symbolic, psychology theories (including observation tools) and individual psychology are both symbolic. This means that theory and the individual can exchange symbols and thereby affect each other. In this sense, psychology cannot be objective, for the nature of the observation tools used can change the system being observed in non-trivial ways. Instead, psychology can be considered to be discourse between the observer or theorist and the subject. Such discourse could become a paradigm for psychology theory.
