Abstract

Kant's general purpose in the first half of his Critique of Pure Reason is to explain the empirical knowledge of the world within the framework of Newtonian physics. Here, the principles of understanding and, particularly, the principles of the relation group are of a higher level of importance. In this paper, through a study of Kant's claims and arguments concerning the third principle of the relation group and considering its relation with the mental succession of ideas in the faculty of imagination, as well as the second principle of this group, the writers deal with the problem of the success of Kant's plan for the philosophical clarification of the third law of Newtonian physics. They also intended to know if the above-mentioned plan is in conformity with other analogies or not.
