Therefore, so it is said, we have now broken definitely with the “dogmatic method of reasoning” of the belief in revelation, and of scholastic philosophy which adhered to absolute truth. They are replaced by the historical-genetical reasoning of the _saeculum historicum_ which “has discarded absolute truth: there are only relative, no eternal truths” (_Paulsen_, Immanuel Kant, 1898, 389). We are further assured that “this treatment of the history of thought prevails in the scientific world; the Catholic Church alone has not adopted it. She still clings to dogmatic reasoning, and that is natural to her; she is sure that she is in possession of the absolute truth” (Idem, Philosophia militans, 2d ed., 1901, 5). Outside of this Church every period of time is free to construct its own theories, which will eventually go with it as they came with it. We meet this relative truth, and all the indefinable hazy notions identified with it, _in all spheres_. The modern history of philosophy and religion concedes to every system and religion the right to their historic position: they are necessary phases of evolution. The notion of immutable problems and truths by which any system of thought would have to be measured has been lost. “The appearance and rejection of a system,” says _J. E. Erdmann_, “is a necessity of world-history. The former was demanded by the character of the time which the system reflected, the latter again is demanded by the fact that the time has changed” (Grundriss der Geschichte der Philosophie, 3rd, I, 1878, 4). And Professor _Eucken_ says: “Despite all its advantages, such a view and construction of life is not a definite truth, it remains an attempt, a problem that always causes new discord among minds” (Grundlinien einer neuen Lebensanschauung, 1907, 2). “Thus, if according to _Hegel_ the coming into being constitutes the truth of being, the ideals and aims also must share in the mobility, and truth becomes a child of the times (_veritas temporis filia_). That apparently subjects life to a full-blown relativism, but such a relativism has lost all its terror by the deterioration of the older method of reasoning. For agreement with existing truth is no longer its chief object.” (Geistige Stroemungen der Gegenwart, 1904, p. 197). The new theory of knowledge assures us quite generally: “It is a vain attempt to single out certain lasting primitive forms of consciousness, acknowledged constant elements of the mind, to retain them. Every ‘a-priori’ principle which is thus maintained as an unalienable dowry of thought, as a necessary result of its psychological and physiological ‘disposition,’ will prove an obstacle of which the progress of science will steer clear sooner or later” (_E. Cassirer_, Das Erkenntnissproblem in der Philosophie und Wissenschaft der neueren Zeit, 1906, 6).
