This book deals with the possibility of an ontological and epistemological account of the psychological category 'neurosis'. Intertwining thoughts from German idealism, Continental philosophy and psychology, the book shows how neurosis precedes and exists independently from human experience and lays the foundations for a non-essentialist, non-rational theory of neurosis; in cognition, in perception, in linguistics and in theories of object-relations and vitalism. The personal essays collected in this volume examine such issues as assimilation, the philosophy of neurosis, aneurysmal philosophy, and the connection between Hegel and Neurosis, among others. The volume establishes the connection between a now redundant psycho-analytic term and an extremely progressive discipline of Continental philosophy and Speculative realism.
