In this essay the author is concerned with the development of Kant's philosophy in which the Critiques lead to the notions of God and religion, in particular reference to his analysis of the 'teleological judgment' in Critique of Judgment. Kant's discussion in this part of the work concerning what makes a human being really moral directs us toward a new phase of thinking beyond the general scheme of Critique of Practical Reason. On this new horizon of thought, a moral human being, in pursuing ultimate good, is supposed to be moving toward the goal of superlative good of humans. And this is exactly where God comes down to relate Himself with humans. It is this idea of the relation between God and humans which provides a key to Kant's perspective on religion (re-ligio).The relation between Divine Being and human beings is considered in terms of its logical structure against the background of the progress from the Critiques to Religion within the Boundaries of Mere Reason.
