Truth Without Truths

Book excerpt: In the context of debates about truth, nihilism is the view that nothing is true. This is a very striking and (at first) implausible thesis, which is perhaps why it is seldom discussed. Truth without Truths applies nihilism to the philosophical debates on truth and paradox, and explores how a nihilist approach to truth is a serious contender. David Liggins demonstrates that a strong case for nihilism about truth is available. The main grounds for taking nihilism on truth seriously are the solutions it provides to a wide range of paradoxes involving truth, and its epistemological superiority to theories that posit truths. The discussion considers a wider range of paradoxes than usual-including the truth-teller paradox and other paradoxes of underdetermination. Liggins shows how the debate over truth and paradox can be advanced by drawing on metaphysical debates about realism and anti-realism. Truth without Truths is also a challenge to deflationism. Deflationists provide an austere, metaphysically lightweight account of truth. But there is one posit that all contemporary deflationists make: they posit truths. By showing that we can well do without truths, Liggins argues that deflationism is actually too lavish a position. Liggins's preferred form of alethic nihilism includes a Ramseyan analysis of the concept of truth, which uses quantification into sentence position, conceived of as non-objectual and non-substitutional. This book is part of a wider movement exploring the implications of admitting forms of non-objectual, non-substitutional quantification-sometimes called 'higher-order metaphysics'.
