Epistemological and ontological problems of the philosophy of technology: "The fourth kingdom" of F. Dessauer

This article considers the concept and a problem of technology in Friedrich Dessauer's works "Philosophy of technology" (1927) and "Dispute on technology" (1959). Ways of statement of the epistemological and ontological questions specific to technology are analyzed. The article shows that the concept of "the fourth kingdom" is an area of rules of the projective, materially expressed reflection which is understood as technology in the true sense. The author proves the thesis that "the fourth kingdom" carries out for projective activity the same functions, as "the world of ideas" of Plato - for the philosophy of receptive activity which has been traditionally investigated in the history. Thereby the platonic philosophy of technology is shown as a perspective area of research within the analysis of projective rules from positions of transcendentalism and the general semiotics.
