Stuart Hampshire remarked in a review in "Mind" that:There is only one property which I can discover to be common to Professor Ryle and Immanuel Kant; in both cases the style is the philosopher - as Kant thought and wrote in dichotomies, Professor Ryle writes in epigrams. There are many passages in which the argument simply consists of a succession of epigrams, which do indeed effectively explode on impact, shattering conventional trains of thought, but which, like most epigrams, leave behind among the debris in the reader's mind a trail of timid doubts and qualifications.John Searle, who has often said that no great work of philosophy contains many footnotes and that philosophical quality varies inversely with the number of bibliographical references, considers the absence of footnotes in "The Concept of Mind" as a sign of its quality.
