The Functions of Transcendental Ego in Kant's Epistemology

Kant's transcendental ego is the absolute and final subject which constitutes the logical foundation of knowledge and experience. It is completely subjective, and as the most necessary and fundamental element in Kant's epistemology is involved in any judgment, intuition, imagination, synthesis, and category and, in a word, in any kind of knowledge and experience which occurs in a priori way. One of the most important and fundamental problems arising about transcendental ego is that of its functions. In this article, we have extracted four functions of transcendental ego according to Kant's own viewpoints in CPR which as follows: 1- transcendental ego provides our knowledge with universality. 2- It provides necessity for our knowledge. 3- It makes possible our knowledge. 4-It unifies our knowledge through the process and act of synthesis. Finally, we came to the conclusion that the function of unification is the most important and fundamental function due to fundamentality and importance of the process of synthesis in Kant’s epistemology.
