The greater vigour of this conception in respect to the opposite, the superiority of philosophy as _methodology_ over philosophy as _metaphysic,_ is shown by the capacity of the former to solve the problems of the latter by criticizing them and pointing out their origin. Metaphysic, on the other hand, is incapable of solving not only the problems of methodology, but even its own problems, without having recourse to the fantastic and arbitrary. Thus questions as to the reality of the external world, of soul-substance, of the unknowable, of dualisms and of antitheses, and so forth, have disappeared in gnoseological doctrines, which have substituted better conceptions for those which we formerly possessed concerning the logic of the sciences, explaining those questions as eternally renascent aspects of the dialectic or phenomenology of knowledge. The view of philosophy as metaphysic is, however, so inveterate and so tenacious that it is not surprising that it should still give some sign of life in the minds of those who have set themselves free of it in general, but have not applied themselves to eradicating it in all its particulars, nor closed all the doors by which it may return in a more or less unexpected manner. And if we rarely find it openly and directly displayed now, we may yet discern or suspect it in one or other of its aspects or attitudes, persisting like kinks of the mind, or unconscious preconceptions, which threaten to drive philosophy as methodology back into the wrong path, and to prepare the return, though but for a brief period, of the metaphysic that has been superseded. It seems to me opportune to provide here a clear statement of some of these preconceptions, tendencies, and habits, pointing out the errors which they contain and entail.
