About the Authors
  • This book analyses and defends the deflationist claim that there is nothing deep about our notion of truth. According to this view, truth is a 'light' and innocent concept, devoid of any essence which could be revealed by scientific inquiry. Cezary Cieśliński considers this claim in light of recent formal results on axiomatic truth theories, which are crucial for understanding and evaluating the philosophical thesis of the innocence of truth. Providing an up-to-date discussion and original perspectives on this central and controversial issue, his book will be important for those with a background in logic who are interested in formal truth theories and in current philosophical debates about the deflationary conception of truth.

    • Puts forward an original defence of the deflationist concept of truth, appealing to students and researchers interested in current philosophical debates
    • Analyses the state of the art in the field, presenting wider analysis of discussions about truth
    • Examines the most up-to-date results on axiomatic truth theories, using technical material to support the claim of the innocence of truth

    Reviews & endorsements

    'I cannot praise this book too highly. I predict that it will constitute indispensable reading for any researcher in the field (professional or postgraduate) for years to come. Many open problems are listed: many of them would constitute excellent subjects of a Ph.D. dissertation in philosophical logic; others set a research agenda that will keep a significant part of the next generation of researchers on axiomatic truth occupied.'
