 Ryle’s campaign against the tendency of philosophers to “hypostasise their own terms of art” lasted throughout his career. Even his very first articles carried the “Occamizing” message that “[p]hilosophical problems are problems of a certain sort; they are not problems of an ordinary sort about special entities” (1971b, vii; these early articles include 1929, 1930a, 1933a, and 1933b).
