We like to think that some things are the case and other things are not. But might it be that everything is the case - that every proposition is true? This book is a sustained critique of what many would regard as the most fundamental of truths: the Law of non-triviality (the claim that only some things are so). The book is a defense of trivialism - the claim that all propositions are true. The author presents a concise and fast paced exploration of a range of topics (including the nature of reality, belief, denial, and truth) that will leave you reeling with indignation. But it sets forth a challenge: philosophers cannot afford to take for granted one of their most cherished assumptions. The book features a preface from the grandfather of dialetheism, Graham Priest.
