Abstract

It is argued that the theories of the modern cognitive psychology of perception and recognition show, under rigorous logical analysis, the same problems which arise in the philosophical theories of knowledge of Descartes and Locke and lead to relativistic and solipsistic consequences. Through examination of the approachs of D. Sanders, E. B. Goldstein and J. Fodor it is shown that the perceptible world in these theories dissolves in internal representations so that despite its realistic starting-point modern cognitive psychology runs into epistemological idealism or solipsism.
