This collection of essays on Saul Kripke and his philosophy is the first and only collection of essays to examine both published and unpublished writings by Kripke. Its essays, written by distinguished philosophers in the field, present a broader picture of Kripke's life and work than has previously been available to scholars of his thought. New topics covered in these essays include vacuous names and names in fiction, Kripke on logicism and de re attitude toward numbers, Kripke on the incoherency of adopting a logic, Kripke on colour words and his criticism of the primary versus secondary quality distinction, and Kripke's critique of functionalism. These essays not only present Kripke's basic arguments but also engage with the arguments and controversies engendered by his work, providing the most comprehensive analysis of his philosophy and writings available. This collection will become a classic in contemporary analytic philosophy.
