This book investigates the polysemy of the category of otherness in Søren Kierkegaard’s authorship as a whole. Leo Stan identifies, expands upon, and discusses the interconnections between four different senses of otherness: the other within the human self, the infinite alterity of God, the paradoxical alterity of Christ, and the alterity of the human other. He also analyzes in detail the three stages of human existence: the aesthetic, the ethical, and the religious. His claim is that in its Kierkegaardian version, otherness can be understood only within the redemption-oriented framework of Christianity and in strict correlation with an ethic of singular persons.
