   • 1949, Gilbert Ryle, The Concept of Mind, Hutchinson, page 16:

     It is one big mistake and a mistake of a special kind. It is, namely, a category-mistake. It represents the facts of mental life as if they belonged to one logical type or category (or range of types or categories), when they actually belong to another. The dogma is therefore a philosopher's myth.
