Fichte: Deducción y Argumentos transcendentales

Johann Gottlieb Fichte not tried simply to explain the content of his philosophy in a fragmentary or essayistic form, but in a systematic form. In developing his philosophical system called Wissenschaftslehre (WL), Fichte always applies a rigorous method. Of course, the adoption of this method and its subsequent application in the several versions of WL is not the result of a casual or arbitrary decision. The characteristics of the method used by Fichte have a strong relationship with the meaning of his philosophical project. In this paper, I try to study the method used by Fichte as a method of "transcendental deduction", which has a strong relationship with the practical significance of his philosophy. Indeed, Fichte explicitly refers to his own method as a "deduction" (Deduction) in his writings Jena´s period (1794-1799). Although this deductive method is originally inspired by the Kantian philosophy, acquires a broader development in the system of Wissenschaftslehre, as a process of foundation on necessary principles of all human knowledge (theoretical and practical). In my point of view, Fichte's transcendental deduction is a complex method, in which three elements are articulated: argumentation, intellectual intuition and reflection. Not only becomes necessary the permanent reference to the constitutive activity of consciousness in each of these methodological dimensions, but also to the practice and its normative principles, originated from the human reason.
