Question

category mistake

Accepted Answer

The first example is of a visitor toOxford. The visitor, upon viewing the collegesand library, reportedly inquired “But where is the University?"[3] The visitor's mistake is presuming that a University is part of the category "units of physical infrastructure" or some such thing, rather than the category "institutions", say, which are far more abstract and complex conglomerations of buildings, people, procedures, and so on. Ryle's second example is of a child witnessing the march-past of a division of soldiers. After having had battalions, batteries, squadrons, etc. pointed out, the child asks when is the division going to appear. 'The march-past was not a parade of battalions, batteries, squadrons and a division; it was a parade of the battalions, batteries and squadrons of a division.' (Ryle's italics) His third example is of a foreigner being shown a cricket match. After being pointed out batsmen, bowlers and fielders, the foreigner asks: 'who is left to contribute the famous element of team-spirit?'

He goes on to argue that the Cartesian dualism of mind and body rests on a category-mistake. In the philosophy of the mind, Ryle's category mistake argument can be used to support eliminative materialism. By using the argument, one can attack the existence of a separate, distinct mind. The argument concludes that minds are not conscious, but a collective predicate for a set of observable behaviour and unobservable dispositions.[4]
