Through the profound questions they ask about human life, we explore the verities of human embodiment from the theist (Kierkegaard, Dostoevsky, Heschel, and Percy) and from the non-theist (Nietzsche, Hesse, Heidegger, Camus, and Sartre) existentialist perspectives: Are there invariants within the human condition? Is human identity essentially tied to its historical-cultural embodiment? Do humans have an essence or nature? Are humans fundamentally different from all other animals? Is there meaning to human life? Are human relationships doomed to failure? Are humans capable of authentic lives? Is the notion of God merely a comforting projection arising out of human weakness? Etc.
