Ryle and Oakeshott on the “Knowing-How/Knowing-That” Distinction

According to Robert Grant, Oakeshott only ever communicated with two “official” philosophers, one of which was Ryle:  Oakeshott warmly introduced Ryle, who delivered the annual August Comte Memorial Lecture at the LSE. John. D. Mabbott who read the proofs for On Human Conduct had, years earlier, been the first to recognize Oakeshott’s KH/KT connection with Ryle in his review of Rationalism in Politics in Mind. Mabbott crossed paths not just with Oakeshott but with Ryle, as a member of Ryle’s “Wee Teas,”philosophical tea parties.
