Paul Montgomery Churchland (born October 21, 1942) is a Canadian philosopher known for his studies in neurophilosophy and the philosophy of mind. After earning a Ph.D. from the University of Pittsburgh under Wilfrid Sellars (1969), Churchland rose to the rank of full professor at the University of Manitoba before accepting the Valtz Family Endowed Chair in Philosophy at the University of California, San Diego (UCSD) and joint appointments in that institution's Institute for Neural Computation and on its Cognitive Science Faculty.
As of February 2017, Churchland is recognised as Professor Emeritus at the UCSD, and is a member of the Board of Trustees of the Moscow Center for Consciousness Studies of Moscow State University. Churchland is the husband of philosopher Patricia Churchland, with whom he collaborates closely.
Paul Montgomery Churchland [2] was born in Vancouver, British Columbia, Canada, on October 21, 1942. [3] [4] Growing up in Vancouver, Churchland's father was a high school science teacher and his mother took in sewing. As a boy, he was obsessed with science fiction; he was particularly struck by the ideas in Robert A. Heinlein's Orphans of the Sky . Churchland liked building things in his father's woodworking and metal shop in their basement, and expected to become an aerodynamical engineer. [5]
At the University of British Columbia, Churchland began with classes in math and physics, intending to pursue engineering. Conversations with fellow students in the summer before his sophomore year inspired him to begin taking philosophy classes. [5] He graduated with a Bachelor of Arts in 1964 [3] [4]
He earned his Ph.D. from the University of Pittsburgh in 1969, [6] his dissertation entitled "Persons and P-Predicates" written with Wilfrid Sellars as his advisor. [2] [3]
In 1969, Churchland took a position at the University of Manitoba, [3] where he would teach for fifteen years, becoming a full professor in 1979. [6] [4] He spent a year at the Institute for Advanced Study in Princeton, [4] and joined the faculty at the University of California, San Diego in 1984. [3] There, he served as Department Chair from 1986–1990. [7]
As of this February 2017, Churchland is recognised as Professor Emeritus at the University of California, San Diego, [8] where he earlier held the Valtz Family Endowed Chair in Philosophy (through 2011), [9] [10] and continues to appear as a philosophy faculty member on the UCSD Interdisciplinary Ph.D. Program in Cognitive Science [11] and with the affiliated faculty of the UCSD Institute for Neural Computation. [12] As of February 2017, he is also a member of the Board of Trustees of the Center for Consciousness Studies of the Philosophy Department, Moscow State University. [13]
Churchland's work is in the school of analytic philosophy in western philosophy, with interests in epistemology and the philosophy of science, and specific principal interests in the philosophy of mind and in neurophilosophy and artificial intelligence. His work has been described as being influenced by the work of W. V. O. Quine, Thomas Kuhn, Russell Hanson, Wilfrid Sellars, and Paul Feyerabend. [14]
Along with his wife, Churchland is a major proponent of eliminative materialism, [15] the belief that
everyday, common-sense, 'folk' psychology, which seeks to explain human behavior in terms of the beliefs and desires of agents, is actually a deeply flawed theory that must be eliminated in favor of a mature cognitive neuroscience. [6]
where by folk psychology is meant everyday mental concepts such as beliefs, feelings, and desires, which are viewed as theoretical constructs without coherent definition, and thus destined to be obviated by a scientific understanding of human nature. From the perspective of Zawidzki, Churchland's concept of eliminativism is suggested as early as his book Scientific Realism and the Plasticity of Mind (1979), with its most explicit formulation appearing in a Journal of Philosophy essay, "Eliminative Materialism and the Propositional Attitudes" (1981). [6]
Churchland believes that beliefs are not ontologically real; that is, that a future, fully matured neuroscience is likely to have no need for "beliefs" (see propositional attitudes), in the same manner that modern science discarded such notions as legends or witchcraft. According to Churchland, such concepts will not merely be reduced to more finely grained explanation and retained as useful proximate levels of description, but will be strictly eliminated as wholly lacking in correspondence to precise objective phenomena, such as activation patterns across neural networks. He points out that the history of science has seen many posits that were considered as real entities: such as phlogiston; caloric; the luminiferous ether; and vital forces that were thus eliminated.[ citation needed ]
Moreover, in The Engine of Reason, The Seat of the Soul Churchland suggests that consciousness might be explained in terms of a recurrent neural network with its hub in the intralaminar nucleus of the thalamus, and feedback connections to all parts of the cortex. He acknowledges that this proposal will likely be found in error with regard to the neurological details, but states his belief that it is on the right track in its use of recurrent neural networks to account for consciousness. This has been described as a reductionist rather than eliminativist account of consciousness.[ citation needed ]
Churchland is the husband of philosopher Patricia Churchland, and it has been noted that, "Their work is so similar that they are sometimes discussed, in journals and books, as one person." [16]
The Churchlands are the parents of two children, Mark Churchland and Anne Churchland, both of whom are neuroscientists. [17]

Professor Churchland has authored several books in philosophy, which have been translated into many languages. [3] His works are as follows:
His book Matter and Consciousness has been frequently and extensively reprinted. [18] Both Scientific Realism and the Plasticity of Mind and A Neurocomputational Perspective have been reprinted. [19]
Professor Churchland has written a number of published articles, some of which have been translated into other languages, including several that have had a substantial impact in philosophy. Essays which have been reprinted include:
Cognitive science is the interdisciplinary, scientific study of the mind and its processes with input from linguistics, psychology, neuroscience, philosophy, computer science/artificial intelligence, and anthropology. It examines the nature, the tasks, and the functions of cognition. Cognitive scientists study intelligence and behavior, with a focus on how nervous systems represent, process, and transform information. Mental faculties of concern to cognitive scientists include language, perception, memory, attention, reasoning, and emotion; to understand these faculties, cognitive scientists borrow from fields such as linguistics, psychology, artificial intelligence, philosophy, neuroscience, and anthropology. The typical analysis of cognitive science spans many levels of organization, from learning and decision to logic and planning; from neural circuitry to modular brain organization. One of the fundamental concepts of cognitive science is that "thinking can best be understood in terms of representational structures in the mind and computational procedures that operate on those structures."
The Chinese room argument holds that a digital computer executing a program cannot have a "mind", "understanding", or "consciousness", regardless of how intelligently or human-like the program may make the computer behave. The argument was presented by philosopher John Searle in his paper "Minds, Brains, and Programs", published in Behavioral and Brain Sciences in 1980. Similar arguments were presented by Gottfried Leibniz (1714), Anatoly Dneprov (1961), Lawrence Davis (1974) and Ned Block (1978). Searle's version has been widely discussed in the years since. The centerpiece of Searle's argument is a thought experiment known as the Chinese room.
Daniel Clement Dennett III is an American philosopher, writer, and cognitive scientist whose research centers on the philosophy of mind, philosophy of science, and philosophy of biology, particularly as those fields relate to evolutionary biology and cognitive science.
Materialism is a form of philosophical monism which holds that matter is the fundamental substance in nature, and that all things, including mental states and consciousness, are results of material interactions of material things. According to philosophical materialism, mind and consciousness are by-products or epiphenomena of material processes, without which they cannot exist. Materialism directly contrasts with idealism, according to which consciousness is the fundamental substance of nature.
The mind is that which thinks, imagines, remembers, wills, and senses, or is the set of faculties responsible for such phenomena. The mind is also associated with experiencing perception, pleasure and pain, belief, desire, intention, and emotion. The mind can include conscious and non-conscious states as well as sensory and non-sensory experiences.
Intentionality is the power of minds to be about something: to represent or to stand for things, properties and states of affairs. Intentionality is primarily ascribed to mental states, like perceptions, beliefs or desires, which is why it has been regarded as the characteristic mark of the mental by many philosophers. A central issue for theories of intentionality has been the problem of intentional inexistence: to determine the ontological status of the entities which are the objects of intentional states.
Eliminative materialism is a materialist position in the philosophy of mind. It is the idea that the majority of mental states in folk psychology do not exist. Some supporters of eliminativism argue that no coherent neural basis will be found for many everyday psychological concepts such as belief or desire, since they are poorly defined. The argument is that psychological concepts of behavior and experience should be judged by how well they reduce to the biological level. Other versions entail the nonexistence of conscious mental states such as pain and visual perceptions.
Patricia Smith Churchland is a Canadian-American analytic philosopher noted for her contributions to neurophilosophy and the philosophy of mind. She is UC President's Professor of Philosophy Emerita at the University of California, San Diego (UCSD), where she has taught since 1984. She has also held an adjunct professorship at the Salk Institute for Biological Studies since 1989. She is a member of the Board of Trustees Moscow Center for Consciousness Studies of Philosophy Department, Moscow State University. In 2015, she was elected a Fellow of the American Academy of Arts & Sciences. Educated at the University of British Columbia, the University of Pittsburgh, and Somerville College, Oxford, she taught philosophy at the University of Manitoba from 1969 to 1984 and is married to the philosopher Paul Churchland. Larissa MacFarquhar, writing for The New Yorker, observed of the philosophical couple that: "Their work is so similar that they are sometimes discussed, in journals and books, as one person."
In philosophy of mind, the hard problem of consciousness is to explain why and how humans and other organisms have qualia, phenomenal consciousness, or subjective experiences. It is contrasted with the "easy problems" of explaining why and how physical systems give a (healthy) human being the ability to discriminate, to integrate information, and to perform behavioral functions such as watching, listening, speaking, and so forth. The easy problems are amenable to functional explanation: that is, explanations that are mechanistic or behavioral, as each physical system can be explained purely by reference to the "structure and dynamics" that underpin the phenomenon.
Neurophilosophy or philosophy of neuroscience is the interdisciplinary study of neuroscience and philosophy that explores the relevance of neuroscientific studies to the arguments traditionally categorized as philosophy of mind. The philosophy of neuroscience attempts to clarify neuroscientific methods and results using the conceptual rigor and methods of philosophy of science.
Stephen P. Stich is an American academic who is Distinguished Professor of Philosophy and Cognitive Science at Rutgers University, as well as an Honorary Professor in Philosophy at the University of Sheffield. Stich's main philosophical interests are in the philosophy of mind, epistemology, and moral psychology. His 1983 book, From Folk Psychology to Cognitive Science: The Case Against Belief, received much attention as he argued for a form of eliminative materialism about the mind. He changed his mind, in later years, as indicated in his 1996 book Deconstructing the Mind.
In philosophy of mind, the computational theory of mind (CTM), also known as computationalism, is a family of views that hold that the human mind is an information processing system and that cognition and consciousness together are a form of computation. Warren McCulloch and Walter Pitts (1943) were the first to suggest that neural activity is computational. They argued that neural computations explain cognition. The theory was proposed in its modern form by Hilary Putnam in 1967, and developed by his PhD student, philosopher, and cognitive scientist Jerry Fodor in the 1960s, 1970s, and 1980s. It was vigorously disputed in analytic philosophy in the 1990s due to work by Putnam himself, John Searle, and others.
William Hirstein is an American philosopher primarily interested in philosophy of mind, philosophy of language, metaphysics, cognitive science, and analytic philosophy. He is a professor of philosophy at Elmhurst University.
Jeffrey Locke Elman was an American psycholinguist and professor of cognitive science at the University of California, San Diego (UCSD). He specialized in the field of neural networks.
Mark Rowlands is a Welsh writer and philosopher. He is Professor of Philosophy at the University of Miami, and the author of several books on the philosophy of mind, the moral status of non-human animals, and cultural criticism. He is known within academic philosophy for his work on the animal mind and is one of the principal architects of the view known as vehicle externalism, or the extended mind, the view that thoughts, memories, desires and beliefs can be stored outside the brain and the skull. His works include Animal Rights (1998), The Body in Mind (1999), The Nature of Consciousness (2001), Animals Like Us (2002), and a personal memoir, The Philosopher and the Wolf (2008).
Philosophy of mind is a branch of philosophy that deals with the nature of the mind and its relation to the body and the external world.
The mind–body problem is a philosophical problem concerning the relationship between thought and consciousness in the human mind, and the body.
Neuroepistemology is an empirical approach to epistemology—the study of knowledge in a general, philosophical sense—which is informed by modern neuroscience, especially the study of the structure and operation of the brain involving neural networks and neuronal epistemology. Philosopher Patricia Churchland has written about the topic and, in her book Brain-Wise, characterised the problem as "how meat knows". Georg Northoff, in his Philosophy of the Brain, wrote that it "focuses on direct linkage between the brain on one hand and epistemic abilities and inabilities on the other."
Keith Frankish is a British philosopher specializing in philosophy of mind, philosophy of psychology, and philosophy of cognitive science. He is an Honorary Reader at the University of Sheffield, UK, Visiting Research Fellow with The Open University, and adjunct Professor with the Brain and Mind Programme at the University of Crete. He is known for his "illusionist" stance in the theory of consciousness. He holds that the conscious mind is a virtual system, a trick of the biological mind. In other words, phenomenality is an introspective illusion. This position is in opposition to dualist theories, reductive realist theories, and panpsychism.
Philip Goff is a British author, idealist philosopher, and professor at Durham University whose research focuses on philosophy of mind and consciousness. Specifically, it focuses on how consciousness can be part of the scientific worldview. Goff holds that materialism is incoherent and that dualism leads to "complexity, discontinuity and mystery". Instead, he advocates a "third way", a version of Russellian idealist monism that attempts to account for reality's intrinsic nature by positing that consciousness is a fundamental, ubiquitous feature of the physical world. "The basic commitment is that the fundamental constituents of reality—perhaps electrons and quarks—have incredibly simple forms of experience."
[Quote:] PMC was born a Canadian and earned a B.A. from the University of British Columbia, and in 1969, he was awarded a Ph.D. in Philosophy from the University of Pittsburgh. There, he wrote a dissertation under the direction of Wilfrid Sellars. He spent the first 15 years of his career at the University of Manitoba, taking advantage of its relative isolation to further develop his own approach to the ideas to which he was exposed during his graduate education. ... His second book, Matter and Consciousness (1984, revised and updated 1988; translated into five languages), has become one of the most popular textbooks in the philosophy of mind.Note, this link presents only an excerpt of the chapter, the first 10 pages.
In more recent history, eliminative materialism has received attention from a broader range of writers, including many concerned not only with the metaphysics of the mind, but also the process of theory change, the status of semantic properties, the nature of psychological explanation and recent developments in cognitive science. Much of this attention has been fostered by the husband-wife team of Paul and Patricia Churchland, whose writings have forced many philosophers and cognitive scientists to take eliminativism more seriously.
