This volume presents current thought and criticism on evolutionary epistemology -- the evolution of knowledge and knowing. As the theme of the fourth T.C. Schneirla Conference held at Wichita State University, evolutionary epistemology was examined from several diverse areas of study including comparative, developmental, physiological, and cultural psychology as well as philosophy. Theories of the Evolution of Knowing addresses alternatives to the genetic determinism inherent in Donald Campbell's concept of genetic epistemology. The concept of integrative levels is shown to offer a parsimonious, non- reductionist approach to the development of "knowing" as a human capacity.
