Deduction Of Concepts Research Articles

Дедукция свободы vs дедукция опыта в метафизике И. Канта

My aim is to demonstrate the specificities and differences between transcendental deduction of concepts and deduction of the fundamental principles of pure practical reason in Kant’s metaphysics. First of all it is necessary to examine Kant’s attitude to the metaphysics of his time and the problem of its new justification. Kant in his philosophy explicated not only the theoretical world of cognition, but also the practical world of freedom. Accordingly, the fundamental means of proving metaphysics’ claims are the deduction of pure concepts of understanding (deduction of experience) and the deduction of the principles of pure practical reason (deduction of freedom). The underlying premises of the Kantian project of reviving metaphysics, “the Copernican Turn”, the critical methods and basic principles of transcendental (formal) idealism also provide the methodological basis of transcendental deduction, a new method of proving the claims of metaphysics in various spheres of human being. Proceeding from the above, I analyse the essence, structure and the peculiarities as well as the differences between the deduction of experience and the deduction of freedom. I single out the following features of the two types of deduction. First, theoretical use of reason is aimed at objects while practical reason is aimed at noumena, the foundations of will and freedom. Second, the transcendental deduction of space and time, as well as the deduction of categories, is preceded by transcendental reduction, which is absent in the deduction of freedom. Third, Kant orients the methodological movement of deductions in opposite directions. Theoretical deduction proceeds from pure forms of sensible intuition to concepts of understanding and thence to fundamental principles. Practical deduction proceeds from a priori principles to the concepts of the metaphysics of morals and thence to moral feelings. Fourth, deduction in the theoretical sphere forbids speculative reason to go beyond experience. Practical deduction has pointed to the intelligible world and has proved its “legitimacy”.

Fichtes Deduktion praktischer Spontaneität

Abstract: In this essay I make an attempt at sketching the outlines of Fichte’s method of philosophical construction in intuition and try to explore the rationality of his concept of deduction. I discuss the relationship between Fichte’s method of philosophical construction and Kant’s concept of construction of geometrical figures in pure intuition. I offer in-depth analysis of Fichte’s deduction of concepts in his Foundations of Natural Rights and in the Wissenschaftslehre nova methodo. However, I argue that Fichte’s deduction of practical spontaneity is not successful. Finally, I consider and reject some objections to my interpretation.
