The phrase Without Authority is Soren Kierkegaard's way of designating his lack of clerical ordination and to raise the complex and central human issue of authority in human culture. Authors of the essays in IKC-18 demonstrate how Kierkegaard's literary genius, religious passion, and intellectual penetration handle with equal ease and acuity the lily of the field, the bird of the air, the sacrament of holy communion, and the concepts of martyr, witness, genius, prototype, and apostle to create a singular and 'authoritative' contribution to both theology and philosophy of religion.
