Garrison's recent article provides another analysis of the need for the inclusion of a relativistic theoretical structure for doing psychological work that adopts some notion related to compementarity for integrating distinct relativistic positions. Problems in his historical account of the introduction of this approach are addressed. Issues concerned with interpretation by psychologists, including Garrison, of modern physical theory are also discussed and point toward the unique contribution that psychologists can bring to understanding modern physical theory. The central significance of psychologists' (...) exploration of modern physical theory is addressed through discussing evidence in this theory of an unavoidable link between the observing, thinking person and the physical world.
