To these I propose to advert in their order; but chiefly to the former, because, in the first place, a special reference to the Method itself is mainly relevant in an introduction to the Discourse on Method, and because, in the second place, a formal though general discussion of the results of the Cartesian Method must far exceed the limits of the present introduction. Certain of the prominent results of the Method will, however, fall to be noticed as illustrative of the characters of the Method itself: and certain of the more general relations of Descartes to succeeding philosophers will be indicated in conclusion.
OF THE METHOD OF DESCARTES.
The Method of Descartes has a preliminary, the character of which it is necessary precisely to ascertain.
The preliminary to the Method is Doubt. This leads us to inquire, in the first place, into the nature of the Cartesian Doubt.
