This book elucidates and defends C.S. Peirce’s pragmatist account of truth. Peirce was interested in exploring truth’s connections to the practices of inquiry, belief, and assertion. This distinctly pragmatic project resulted in the view that truth is what would be agreed upon, were inquiry to be pursued as far as it could fruitfully go. The view that a belief is true if it would be indefeasible connects truth to human practices, but which takes truth to be something to be discovered. That is, Peirce’s view of truth is much more objectivist than some currently popular brands of pragmatism. In this expanded edition, advances in the understanding of Peirce’s theory of truth are noted, and include a new chapter which shows how Peirce’s view of truth is friendly to moral judgements.
