Peter Hacker is a British philosopher known for work in philosophy of mind, philosophy of language, and Wittgensteinian scholarship. He trained at University of Oxford and held chairs at University of Sheffield and University of Oxford, producing influential critiques of cognitive science, Cartesianism, and reductionist interpretations of neuroscience. His writings engage with figures such as Ludwig Wittgenstein, Gilbert Ryle, G. E. Moore, John Searle, and Daniel Dennett.

Early life and education

Hacker was born in London in 1939 and educated at University of Oxford, where he read Greats and later studied philosophy under tutors influenced by Ordinary Language Philosophy and the legacy of G. E. Moore. During his formative years he encountered the texts of Ludwig Wittgenstein, Gilbert Ryle, and Bertrand Russell, developing an interest in the interplay between ordinary speech and the analysis of mental predicates. His doctoral and post-graduate studies involved close textual work on Wittgenstein and historical figures such as David Hume and Immanuel Kant.

Academic career

Hacker held academic posts at University of Sheffield and later at University of Oxford, where he served as Professor of Philosophy and taught in the Faculty of Philosophy, University of Oxford. He supervised doctoral students who went on to positions at institutions like University College London, King's College London, and Princeton University. Hacker contributed to editorial boards for journals associated with British Academy publications and collaborated with scholars from Harvard University, Columbia University, and University of Chicago on projects concerning philosophy of mind and analytic philosophy. He frequently lectured at venues such as Cambridge University, Yale University, Stanford University, and the University of California, Berkeley.

Philosophical work and ideas

Hacker’s philosophy is centrally informed by close readings of Ludwig Wittgenstein and the tradition associated with Ordinary Language Philosophy. He defends a form of anti-reductionism regarding mental vocabulary, arguing against eliminativist tendencies in neurology and against computational models favored by cognitive science proponents such as Jerry Fodor and Daniel Dennett. Drawing on Gilbert Ryle’s critique of Cartesian dualism and on G. E. Moore’s ordinary-language clarity, Hacker emphasizes the distinctions among ascription, manifestation, and explanation of psychological predicates. His collaboration with Max Bennett addressed misunderstandings between philosophers and neuroscientists by clarifying conceptual frameworks used in neurophysiology and pharmacology.

Hacker developed a Wittgensteinian method for dissolving philosophical puzzles by analyzing linguistic practice and critiqued metaphysical theorizing detached from ordinary speech, engaging with critics like John Searle and proponents of representational theories of mind such as Hilary Putnam. He argued that many philosophical errors arise from category mistakes similar to those described by Gilbert Ryle and provided sustained critiques of accounts that ascribe mental states directly to brain processes rather than to whole persons situated in social practices. Hacker’s approach underlines the normative role of ordinary-language grammar in philosophical clarification, drawing comparisons with analytic tradition figures including Bertrand Russell and G. E. Moore.

Major publications

Hacker’s major works include Insight and Illusion, a study in philosophical methodology; Philosophical Foundations of Neuroscience, co-authored with Max Bennett; and extensive expositions on Wittgenstein such as his commentaries and compilations of Philosophical Investigations scholarship. Other notable titles are A Companion to Wittgenstein's Philosophical Investigations, The Intellectual Powers, and collections of essays addressing mind–body problem debates and critiques of cognitive neuroscience. His publications engage with contemporary controversies involving authors like Patricia Churchland, Paul Churchland, John McDowell, and Saul Kripke.

Honors and recognition

Hacker has been recognized by bodies such as the British Academy and received honorary degrees from institutions including University of St Andrews and University of Edinburgh. He was awarded fellowships and visiting professorships at centers like Institute for Advanced Study and delivered named lectures at organizations including Royal Institute of Philosophy and American Philosophical Association conferences. His work has been the subject of symposia at universities such as Oxford, Cambridge, and Columbia University, and has influenced curricula in departments of philosophy at King's College London, University of Toronto, and Australian National University.

Personal life and legacy

Hacker’s personal life has been private; he maintained scholarly collaborations and mentorship networks across Europe and North America. His legacy includes fostering a generation of philosophers trained in close textual exegesis and ordinary-language analysis, shaping debates between analytic philosophers and neuroscientists, and reinvigorating interest in Wittgensteinian methods. His critiques continue to be cited in discussions involving philosophy of mind, neuroscience, analytic philosophy, and the interpretation of psychological vocabulary, ensuring ongoing engagement in seminars and conferences at institutions like Princeton University, Harvard University, and University of Oxford.
