Knowledge tree Descartes' classification and the causes of its disappearance

The purpose of categorization or classification is not to separate knowledge from one another, but at the same time recognize them, show the relationships and correlations of knowledge with each other and clarify the unity of science. The used research method is content analysis method. The data collection tool is a priori information resource that has been dealt with in the Descartes Knowledge tree. Descartes' comments and criticisms that were studied by previous studies and the reasons for its disappearance were discussed. The results of this study showed that the reasons for deconcentration of Descartes' classification are unity and the absence of a comprehensive knowledge of both quantitative and behavioral sciences and humanities, the lack of attention to the humanities in general, the lack of consideration of the relation between all sciences as well as the relation among sciences with human needs, the classification of knowledge Instead of classifying science, science is more generally than the knowledge semantically, putting science that is independent today as a subset of mathematics and metaphysics, is considered Descartes' classification only as a hierarchy and the relationships among different sceinces and the interdisciplinary nature of sciences are not included
