Abstract

This chapter discusses Decartes as a rationalist and an experimentalist, as a philosopher-metaphysicist who also relies on experiment and observation as an essential activity of knowledge. It explains deduction in terms of intuition, its connection between one proposition and another as the only way to knowledge and method, as some sets of rules, easy rules that should someone follow them, will lead to the truth. It further explains Descartes concept of the anaclastic which depends on the angle of incidence and the angle of refraction. This chapter also explains Decartes thought that intuition and deduction are the immediate grasping of the propositions and inferential connection between propositions. Finally this chapter explains how certain experiments are needed to arrived at certain knowledge through deduction.
