Abstract
Such a serious historical journey into the country of ideas as is demanded by the present topic should give one initial pause for salutary reflection. That this should be the case is due in no small way to the fact that one must be prepared, equivalently, to pay court, woo and win not one—task enough in itself—but two ladies–in–waiting. They are no less than Clio, the Muse of History and the fair Lady Philosophy. In the spirit of monogamy, one may well wish to speak of Cliophil, the Muse of the History of Philosophy.
