I begin these publications with the fragment of my last attempt to arrange my philosophical thoughts in an ordered sequence. This fragment has perhaps the advantage of giving comparatively easily an idea of my method. I intend to follow up this fragment with a mass of remarks more or less loosely arranged; and I shall explain the connections between my remarks, where the arrangement does not itself make them apparent, by a system of cross-references thus: each remark shall have a current number and besides this the numbers of those remarks which stand to it in important relations.
