Gilbert Ryle: The Concept of Mind & Philosophy

Biography

Gilbert Ryle was born on August 19, 1900, in Brighton, England, into a family with a strong intellectual tradition. His father, John Alfred Ryle, was a doctor, and the family counted several distinguished scholars among its members. Ryle attended Brighton College and then Queen's College, Oxford, where he read classics and philosophy. His studies were interrupted by the First World War, during which he served with the British Army, and he returned to Oxford to complete his education after the conflict.

Ryle spent almost his entire academic career at Oxford. He was appointed a lecturer at Christ Church in 1924 and later became the Waynflete Professor of Metaphysical Philosophy, a chair he held from 1945 until his retirement in 1968. As editor of the journal Mind from 1947 to 1962, Ryle occupied one of the most influential positions in the English-speaking philosophical world, shaping the direction of analytic philosophy during its most fertile period. He died on October 6, 1976, in Whitby, Yorkshire.

Historical Background

Ryle's philosophy must be understood against the background of the philosophical revolution that swept through Oxford in the 1930s and 1940s. The movement known as ordinary language philosophy — associated above all with the later Wittgenstein and with J. L. Austin — held that many traditional philosophical problems arise from the misuse of language. When philosophers ask questions like "What is the mind?" they are not discovering a deep mystery; they are being misled by the grammar of their own sentences.

The specific target of Ryle's most famous work was Cartesian dualism, the view, inherited from Descartes, that the mind is a non-physical substance that inhabits and interacts with the physical body. On the Cartesian picture, each human being is a compound of two utterly different kinds of thing: a body, which is extended in space and subject to physical laws, and a mind, which is unextended, private, and the seat of consciousness and thought. This picture, Ryle argued, is not a discovery but a confusion — a "category mistake" of the most consequential kind.

Core Ideas

The Category Mistake

Ryle's central diagnostic tool is the notion of a category mistake. A category mistake occurs when facts of one logical type are presented as if they belonged to another. Ryle's famous illustration is the visitor to Oxford who, after being shown the colleges, libraries, and offices, asks "But where is the University?" The visitor is not ignorant of any particular fact; he has misrepresented the logical category to which the University belongs. It is not one more item alongside the colleges but the way the colleges are organized.

Ryle applies this diagnosis to the mind-body problem. The dualist treats the mind as if it were one more thing alongside the body — an inner, non-physical object that observes, decides, and initiates action. But the mind, Ryle argues, is not a thing of this kind at all. To speak of a person's mind is to speak of their dispositions, abilities, and tendencies to behave in certain ways. The dualist's question — how does the immaterial mind interact with the material body? — is the product of a category mistake, and once the mistake is exposed the question dissolves.

The Ghost in the Machine

Ryle's most memorable phrase is "the ghost in the machine." The Cartesian picture, he wrote, represents a person as "a ghost mysteriously ensconced in a machine." This picture generates a host of pseudo-problems: How can the ghost control the machine? How can the machine transmit information to the ghost? How can two ghosts know that other ghosts exist? None of these questions has an answer, Ryle argued, because the picture that generates them is fundamentally confused. The Cartesian myth is not a theory that fails but a mistake about what kind of thing a mind is.

Logical Behaviorism

Ryle's positive account of the mind is often called logical behaviorism. Mental concepts, he argued, do not refer to inner, private events; they refer to publicly observable patterns of behavior and dispositions to behave. To say that someone is vain is not to report the occurrence of a private feeling of vanity but to describe a tendency — a tendency to talk about oneself, to seek admiration, to feel wounded by criticism. Statements about the mind are, in Ryle's terms, "inference tickets": they license us to expect certain behaviors in certain circumstances. This is not the psychological behaviorism of John Watson or B. F. Skinner, which denied the reality of mental life; it is a logical thesis about what mental concepts mean.

Knowing-How and Knowing-That

A lasting contribution of The Concept of Mind is the distinction between knowing how and knowing that. Knowing that is propositional knowledge — knowledge of facts, expressible in statements. Knowing how is practical knowledge — the ability to do things, like ride a bicycle or speak a language. Ryle argued that the intellectualist legend — the view that intelligent action always involves the prior contemplation of propositions — leads to an infinite regress: if acting intelligently requires consulting a rule, then consulting the rule is itself an action that requires a rule, and so on. The regress is broken only by recognizing that knowing how is a distinct, primitive form of intelligence that cannot be reduced to knowing that.

Major Works

The Concept of Mind (1949) is Ryle's masterpiece and one of the most influential works in twentieth-century philosophy of mind. Its fourteen chapters systematically dismantle the Cartesian picture, examining sensation, imagination, intellect, emotion, and volition, and arguing in each case that mental concepts are to be understood in terms of dispositions and behavior. The book made Ryle famous overnight and launched a generation of debate about the proper analysis of mental concepts.

His earlier Philosophical Arguments (1945) and his later essays, collected in volumes such as Dilemmas (1954) and Collected Papers (1971), develop his views on philosophical method, logic, and the philosophy of language. Ryle also wrote on the history of philosophy, producing influential studies of Plato and of the development of the concept of mind in ancient thought.

Philosophical Influence

Ryle's influence is difficult to overstate. The Concept of Mind effectively ended the dominance of Cartesian dualism in English-speaking philosophy and redirected the philosophy of mind toward the analysis of mental concepts. His attack on the "intellectualist legend" shaped the philosophy of action and the study of skill. His rejection of the inner-outer picture of the mind was carried forward by his student Daniel Dennett, who studied under Ryle at Oxford and later described him as the most important philosophical influence on his work — Dennett's own account of consciousness can be read as a scientifically updated Rylean therapy for the "Cartesian Theater."

Ryle also shaped philosophical methodology. His insistence that philosophical problems often arise from category mistakes, and that the philosopher's task is conceptual clarification rather than speculative system-building, became a hallmark of Oxford philosophy in the mid-twentieth century. Critics have charged that logical behaviorism leaves out the subjective character of experience — the felt quality of mental life that no behavioral disposition seems able to capture. This objection, pressed by figures from Thomas Nagel to John Searle, marks the limit of Ryle's program; but even his critics concede that he permanently changed the terms of the debate.

Related Concepts

Ryle's work connects directly to several core themes in the philosophy of mind. His critique of the ghost in the machine is the ancestor of contemporary functionalism and of Dennett's multiple drafts model. His account of mental concepts as dispositions prefigures the behaviorist strand in the theory of mind explored in what is behaviorism. His rejection of the inner-outer picture bears on the question of what is the self and on the understanding of self-knowledge. And his method of dissolving problems rather than solving them remains a model for analytic philosophy. For anyone seeking to understand why the mind-body problem took its modern shape, Ryle is the essential starting point.
