This is a book on the metaphysics of contingency. It looks at what could be otherwise, at what lacks the weight of necessity, at what is up for grabs. Aristotle maintained that there could be no knowledge of the impermanent. Since then, metaphysics has endeavored to find out what really is permanent, non-accidental and resilient - substances that endure, substrata underneath different qualities, fixed principles, necessary connections. In contrast, Bensusan draws on the growing philosophical attention to the contingent. A speculative and anarcheological effort, Being up for Grabs aims to reach a broad and encompassing view of the sensible world while conceiving it as lacking any arché. The book emerges as a remarkable exercise in speculative anarcheology.
