Vision Theory of Descartes

The traces of epistemological items of Descartes, which make him the fuounder of modern philosophy, are seen in his vision theory. The dualism, which is seen in the Descartes’s philosophy, spreads each element of his vision theory. One of the starting points in the reasoning that led Descartes to the inference of “ego cogito ergo sum” is the view that the senses are not be trusted to obtain information. This determination is one of the important points of his vision theory as welle as his theory of perception. Criticizing Aristotle’s perception theory, Descartes developed his own mechanical philosophy of nature. Descartes, which forms a vision theory parallel to this mechanical philosophy of nature, has a similar attitude to the approaches of Ancient Greek thinkers who deal with the problem of vision geometrically. In terms of Descartes, there must be a spiritual intervention in order for visualization to take place. According to Descartes, who has made a comparison between light and a cane used by blind people, seeing is a spatial perception. Contrary to the theory of images which suggests that images resemble their objects, Descartes considers that images represent the objects in which they are displayed in our minds and therefore represent the objects in which they are displayed. For this reason it can be argued that Descartes’ philosophy is representational
