Gilbert Ryle (19 August 1900-6 October 1976), was a British philosopher, and a representative of the generation of British ordinary language philosophers influenced by Wittgenstein's insights into language, and is principally known for his critique of Cartesian dualism, for which he coined the phrase "the ghost in the machine". Some of his ideas in the philosophy of mind have been referred to as "behaviourist" (not to be confused with the psychological behaviourism of B. F. Skinner and John B. Watson). Ryle himself said that the "general trend of this book [The Concept of Mind, p. 327] will undoubtedly, and harmlessly, be stigmatised as 'behaviourist'."
A capable linguist, he was recruited to intelligence work during World War II, after which he returned to Oxford and was elected Waynflete Professor of Metaphysical Philosophy and Fellow of Magdalen College, Oxford. He published his principal work, "The Concept of Mind" in 1949. He was president of the Aristotelian Society from 1945 to 1946, and editor of the philosophical journal Mind from 1947 to 1971. Ryle died on 6 October 1976 at Whitby, North Yorkshire.
Ryle offers the analogy of philosophy as being like cartography. Competent speakers of a language, Ryle believes, are to a philosopher what ordinary villagers are to a mapmaker. The ordinary villager has a competent grasp of his village, and is familiar with its inhabitants and geography. However, when asked to consult a map for the same knowledge he has practically, the villager will have difficulty until she is able to translate her practical knowledge into universal cartographal terms. The villager thinks of the village in personal and practical terms while the mapmaker thinks of the village in neutral, public, cartographical terms.
By "mapping" the words and phrases of a particular statement, philosophers are able to generate what Ryle calls "implication threads." In other words, each word or phrase of a statement contributes to the statement in that, if the words or phrases were changed, the statement would have a different implication. The philosopher must show the directions and limits of different implication threads that a "concept contributes to the statements in which it occurs." To show this, he must be "tugging" at neighbouring threads, which, in turn, must also be "tugging." Philosophy, then, searches for the meaning of these implication threads in the statements in which they are used.
He attacks the idea of 17th and 18th century thinkers (such as Descartes) that nature is a complex machine, and that human nature is a smaller machine with a "ghost" in it to account for intelligence, spontaneity and other such human qualities. While mental vocabulary plays an important role in describing and explaining human behavior, neither are humans analogous to machines nor do philosophers need a "hidden" principle to explain their super-mechanical capacities.
Ryle asserted that the workings of the mind are not distinct from the actions of the body. They are one and the same. Mental vocabulary is, he insists, merely a different manner of describing action. He also claimed that the nature of a person's motives are defined by that person's dispositions to act in certain situations. There are no overt feelings, pains, or twinges of vanity. There is instead a set of actions and feelings that are subsumed under a general behavior-trend or propensity to act, which we term "vanity."
Novelists, historians and journalists, Ryle points out, have no trouble in ascribing motives, moral values and individuality to people's actions. It is only when philosophers try to attribute these qualities to a separate realm of mind or soul that the problem arises. Ryle also created the classic argument against cognitivist theories of explanation, Ryle's Regress.
Ryle's notion of thick description, from "The Thinking of Thoughts: What is 'Le Penseur' Doing? and "Thinking and Reflecting", has been an important influence on cultural anthropologists like Clifford Geertz.
Allan Bloom, a classicist and Greek scholar now best known for his controversial The Closing of the American Mind, was harshly critical of Ryle, writing: "In themselves Ryle's opinions are beneath consideration, but they do deserve diagnosis as a symptom of a sickness which is corrupting our understanding of old writers and depriving a generation of their liberating influence...Such scholarship should give us pause, for Ryle is held by many to be one of the preeminent professors of philosophy in the Anglo-Saxon world. Bloom's central criticism indicts Ryle for anachronistically "Aristotelianizing" Platonic texts, thereby putting them through an artificial "analytic strainer." According to Bloom, this mediation vitiates the content of Plato's text by "torturing Plato to conform to a dogmatic starting point," rather than entering at the natural beginning.
