Crispin Wright (born 1942) is a British philosopher, who has written on neo-Fregean philosophy of mathematics, Wittgenstein's later philosophy, and on issues related to truth, realism, cognitivism, skepticism, knowledge, and objectivity. He was born in Surrey and was educated at Birkenhead School (1950–61) and at Trinity College, Cambridge, graduating in Moral Sciences in 1964 and taking a PhD in 1968.

  • Crispin Wright (born 1942) is a British philosopher, who has written on neo-Fregean philosophy of mathematics, Wittgenstein's later philosophy, and on issues related to truth, realism, cognitivism, skepticism, knowledge, and objectivity. He was born in Surrey and was educated at Birkenhead School (1950–61) and at Trinity College, Cambridge, graduating in Moral Sciences in 1964 and taking a PhD in 1968. He took an Oxford BPhil in 1969 and was elected Prize Fellow and then Research Fellow at All Souls College, Oxford, where he worked until 1978. He then moved to the University of St. Andrews, where appointed Professor of Logic and Metaphysics and then the first Bishop Wardlaw University Professorship in 1997. As of fall 2008, professor at New York University (NYU), though he will also continue to teach at the University of St. Andrews. He has also taught at the University of Michigan, Oxford University, Columbia University, and Princeton University. Crispin Wright is founder and director of Arché (research center), which he will leave in September 2009 to take up leadership of the new Northern Institute of Philosophy(NIP) at the University of Aberdeen (Scotland). In the philosophy of mathematics, he is best-known for his book Frege's Conception of Numbers as Objects (1983), where he argues that Frege's logicist project could be revived by removing the Principle of Unrestricted Comprehension (sometimes referred to as Basic Law V) from the formal system. Arithmetic is then derivable in second-order logic from Hume's principle. He gives informal arguments that (i) Hume's principle plus second-order logic is consistent, and (ii) from it one can produce the Dedekind–Peano axioms. Both results were proven informally by Gottlob Frege, and would later be more rigorously proven by George Boolos and Richard Heck. Wright is one of the major proponents of neo-logicism, alongside his frequent collaborator Bob Hale. In general metaphysics, his most important work is Truth and Objectivity (Waynflete Lectures given at Oxford), Cambridge, MA, 1992. He argues in this book that there need be no single, discourse-invariant context in which truth consists, making an analogy with identity. There need only be some principles regarding which the truth predicate can be applied to a sentence, some 'platitudes' about true sentences. Wright also argues that in some contexts, probably including moral contexts, superassertibility will effectively function as a truth predicate. He defines a predicate as superassertible if it is "assertible" in some state of information and then remains so no matter how that state of information is enlarged upon or improved. Assertibility is warrant by whatever standards inform the discourse in question. Many of his most important papers in philosophy of language, epistemology, philosophical logic, meta-ethics, and the interpretation of Wittgenstein have been collected in two volumes published by Harvard University Press.

Danach wurde er Professor für Logik und Metaphysik an der University of St. Andrews. 2008 wurde er zusätzlich Professor an der New York University. 1983 schrieb er sein Hauptwerk Frege's Conception of Numbers as Objects. Darin beschrieb er Freges Theorem, dass Peano-Axiome der Arithmetik aus Humes Prinzip mittels einer Logik zweiter Stufe abgeleitet werden können, indem man auf das Grundgesetz der Werthverläufe (V), das direkt zur Russellschen Antinomie führt, verzichtet. Formale Beweise für das Theorem folgten von George Boolos und Richard Heck. Wright wurde zusammen mit Bob Hale zum Begründer des Neo-Logizismus.
