The methodology or logic of history has supplanted the philosophy of history; an epistemology of the concepts employed in the natural sciences succeeded the Philosophy of Nature. What philosophy can study of history is its mode of construction (intuition, perception, document, probability, etc.); of the natural sciences the forms of the concepts which constitute them (space, time, motion, number, types, classes, etc.). Philosophy as metaphysic in the sense above described would, on the other hand, claim to compete with history and with the natural sciences, which alone are legitimate and effective in their field. Such a challenge could do nothing but reveal the incompetence of those who made it. In this sense we are _anti-metaphysicans,_ while declaring ourselves to be _ultra-metaphysicians,_ when the word is used to claim and to affirm the office of philosophy as self-consciousness of the spirit, distinguished from the merely empirical and classificatory office of the natural sciences. [Sidenote: _Mental imagination and the intuitive intellect._] Metaphysic has been obliged to assert the existence of a specific spiritual activity producing it, in order to maintain itself side by side with the sciences of the spirit. This activity, called in antiquity _mental or superior imagination,_ and more often in modern times _intuitive intellect or intellectual intuition,_ was held to unite the characters of imagination and intellect in an altogether special form. It was supposed to provide the means of passing by deduction or dialectic from the infinite to the finite, from form to matter, from the concept to the intuition, from science to history, acting by a method which was held to penetrate both the universal and the particular, the abstract and the concrete, intuition and intellect. A faculty marvellous indeed and most valuable to possess; but we, who do not possess it, have no means of establishing its existence. [Sidenote: _Mystical Æsthetic._] Intellectual intuition has sometimes been considered to be the true æsthetic activity. At others a no less marvellous æsthetic activity has been placed beside, below, or above it, a faculty altogether different from simple intuition. The glories of this faculty have been celebrated, and the production of art attributed to it, or at least of certain groups of artistic production, arbitrarily chosen. Art, religion and philosophy have seemed in turn to be one only, or three distinct faculties of the spirit, sometimes one, sometimes another of them being supreme in the dignity shared by all.
