This book is the first of three volumes of ‘autonomous works, coordinated by the material of their themes and objects and unified by their practice of thought’, which François Laruelle calls the ‘Triptych’ (ix). Intended to be a philosophico-religious treatment of the ‘heretic’ question that theology and religious studies apparently raise but fail to lead it to its logical conclusion. Laruelle intends to do this treatment by a non-conventional approach in the streams of heretics, mysticism, and Eros. Laruelle gives a glossary of terms that he invents and rediscovers throughout this book but cautions the reader to be not bound by the definitions and definitely not to systematise these definitions to some other ‘ism’ as that ‘would be contrary to the spirit of non-philosophy which is a practice of—and in—thought’ (x)
