  • Vagueness and Degrees of Truthby Nicholas J. J. Smith

    Oxford University Press 2008; US$ 34.99

    In Vagueness and Degrees of Truth, Nicholas Smith develops a new theory of vagueness: fuzzy plurivaluationism.

  • Paradoxby Jim Al-Khalili

    Transworld 2012; US$ 14.38 US$ 10.79

    This book is about my own personal favourite puzzles and conundrums in science, all of which have famously been referred to as paradoxes, but which turn out not to be paradoxes at all when considered carefully and viewed from the right angle. A true paradox is a statement that leads to a circular and self-contradictory argument, or one that describes... more...

  • The Many Valued and Nonmonotonic Turn in Logicby Dov M. Gabbay; John Woods

    Elsevier Science 2007; US$ 285.00

    The present volume of the Handbook of the History of Logic brings together two of the most important developments in 20th century non-classical logic.
