Abstract
This paper examines how Kant's Copernican shift in philosophy had a decisive influence on philosophical religious thought; reflection on the nature of subjectivity shaped how the question of God was approached and understood. I examine three interrelated issues at the forefront of nineteenth and twentieth-century thought on subjectivity and the problem of God. These are a) the ontological nature of subjectivity and what it reveals about the conditions of possibility of a subject's relation to the Absolute; b) interiority and subjectivity with respect to the subject's relation to God, and c) the theme of the "unhappy consciousness" and how its development led to important attacks on theism. I look at these issues as they were worked out by F. Schleiermacher, G.W.F Hegel, S. Kierkegaard, Nietzsche, P. Tillich, and K. Rahner.
