Very few thinkers have traveled the heretical path that François Laruelle walks between philosophy and non-philosophy. For Laruelle, the future of philosophy is problematic, but a mutation of its functions is possible. Up until now, philosophy has merely been a utopia concerned with the past and only provided the services of its conservation. We must introduce a rigorous and nonimaginary practice of a utopia in action, a philo-fiction—a close relative to science fiction. From here we can see the double meaning of the watchword, a tabula rasa of the future. This new destination is imposed by a specifically human messianism, an eschatology within the limits of the Man-in-person as antihumanist ultimatum addressed to the History of Philosophy. This book elucidates some of the fundamental problems of non-philosophy and takes on its detractors.
