Thus materialism is due to the attempt to reduce all of experience to the elements and principles of connection which are employed by the physical sciences to set in order the actual motions, or changes of place, which the parts of experience undergo. Materialism maintains that the motions of bodies are indifferent to considerations of worth, and denies that they issue from a deeper cause of another order. The very ideas of such non-mechanical elements or principles are here provided with a mechanical origin. Similarly a phenomenalism, like that of Hume, takes immediate presence to sense as the norm of being and knowledge. Individual items, directly verified in the moment of their occurrence, are held to be at once the content of all real truth, and the source of those abstract ideas which the misguided rationalists mistake for real truth. But the absolutist, on the other hand, contends that the thinker must _mean_ something by the reality which he seeks. If he had it for the looking, thought would not be, as it so evidently is, a purposive endeavor. And that which is meant by reality can be nothing short of the fulfilment or final realization of this endeavor of thought. To find out what thought seeks, to anticipate the consummation of thought and posit it as real, is therefore the first and fundamental procedure of philosophy. The mechanism of nature, and all matters of fact, must come to terms with this absolute reality, or be condemned as mere appearance. Thus Plato distinguishes the world of "generation" in which we participate by perception, from the "true essence" in which we participate by thought; and Schelling speaks of the modern experimental method as the "corruption" of philosophy and physics, in that it fails to construe nature in terms of spirit.
