The main contention of this book is that Kierkegaards apophaticism is an ethical-religious difficulty, concerning itself with the whylessness of existence. This is a theme that Kierkegaard inherits from the philosophical and theological traditions stemming from Meister Eckhart. The book examines Kierkegaards apophaticism with reference to five themes: indirect communication, God, faith, hope, and love. Across these themes, the aim is to lend voice to the unruly energy of the unsayable and, in doing so, let Kierkegaards theological, spiritual, and philosophical provocation remain a living one for us today.
