The philosophical question of nothingness has often been controversial. The main core of the question is the use of 'nothing' or 'nothingness' as a noun phrase rather than a quantifier phrase. This work deals with the question of nothingness and metaphysical nihilism in analytic philosophy. After evaluating an account of nothingness based on the notion of an empty possible world, the present work proposes two original arguments for metaphysical nihilism. With a preface by Graham Priest. "Simionato's book delivers a welcome deepening of our understanding of nothing." Graham Priest
