It always has been, and still is, the firm conviction of unbiassed men, – a conviction which irresistibly forces itself upon us, – that in our intellectual perception and thought we grasp an objective, exterior order of things, an existence distinct from our thought; of this objective reality we reproduce an image in our minds, and thus grasp it intellectually. Cognitio est similitudo rei, says the old school; that is, Knowledge is the reproduction of an objective reality, which thus becomes the criterion of cognition. The reproduction is a counterpart of the original. In this perfect resemblance of our cognition to the objective reality there has ever been recognized the truth of knowledge.

When the thinking mind has arrived at the mathematical truth that the circumference of a circle is the product of the diameter multiplied by Ludolph's number, it knows – unless indeed it has lost its natural candour – that it has not of itself produced this result of reasoning, but that it has recognized in it an objective reality of truth, distinct from its own thought, and has reproduced that truth in itself. And because this reproduction corresponds to the reality, it is called true cognition. Similarly, when the intellect expresses the general law of causality, namely, everything that happens has a cause, the intellect is again convinced that it has not of itself produced this result of reasoning, but has only reproduced it by assimilating to itself an objective truth which is necessarily so and cannot be otherwise, and which the mind must assimilate if it wants to think aright. This is true not only when the mind is dealing with concrete things, but also when it would give expression to general principles, as in the present instance; these, too, are not subjective projections, but are independent of the thinking subject, and are eternal laws.

This view of the nature of human cognition and thought has gradually undergone an essential change, not indeed with those outside the influence of philosophical speculation, but with the representatives of modern philosophy, and those subject to its influence. Objectivism has been superseded by subjectivism. Its principle is this: cognition, imagination, and thought are not the intellectual apprehension of an objective world existing independent of us, of which we reproduce in ourselves a counterpart. No, the mind creates its own results of reason and cognition; the objects before us are the creatures of the imagining subject. At the utmost, we can but say that our reasoning is the manner in which a hidden exterior world appears to us. This manner must necessarily conform to the peculiarity of the subject, to his faculties and stage of development; but the exterior world as it is in itself we can never apprehend. Descartes, starting with the premise that consciousness is the beginning of all certainty, was the first modern philosopher to enter upon the way of subjectivism. He was followed by Locke, Berkeley, and Kant. It is due to them that in the modern theory of cognition the fundamental principle of idealistic subjectivism, no matter how difficult and unreasonable it may appear to an ordinary thinker, has obtained so many advocates who, nevertheless, cannot adhere to it, but contradict it at every step.

“The world,” Schopenhauer is convinced, “is the projection of my idea… No truth is more certain, more independent of all others, less in need of proof, than this, that all there is to be known, hence the whole world, is an object only in relation to a subject, a vision of the beholder; in a word, the projection of my own idea. Hence the subject is the bearer of the world” (Die Welt als Wille und Vorstellung, I, §§ 1-2). “It is evidently true that knowledge cannot go beyond our consciousness, and hence the existence of things outside of our sphere of consciousness must, to say the least, remain problematical”(Der Gegenstand der Erkenntniss, 1892, p. 2). In like manner O. Liebmann says: “We can never go beyond our individual sphere of ideas (projection of our ideas), even though we apprehend what is independent of us, still the absolute reality of it is known to us only as our own idea” (Zur Analysis der Wirklichkeit, 1900, p. 28). Therefore “the contrast between ‘I’ and the world,”says E. Mach, “between feeling or apprehension and the reality, falls away” (Die Analysis der Empfindungen, 2d ed., 1900, p. 9). And a disciple of Mach says: “It is important to hold fast to the idea that a self-existent, divine Truth, independent of the subject, objectively binding, enthroned, so to say, above men and gods, is meaningless… Such a Truth is nonsense” (H. Kleinpeter, Kantstudien, VIII, 1903, p. 314).

None of these representatives of worldly wisdom are able to fulfil the first duty of the wise man: “Live according to what you teach.” Even the sceptic Hume has to admit that in the common affairs of life he feels himself compelled of necessity to talk and act like other people.

Subjectivism is really nothing but scepticism, for it eliminates the knowableness of objective truth. But it is a masked – if you will, a reformed – scepticism. Cognition is given another purpose; its task is not at all, so it is said, to reproduce or assimilate a world distinct from itself, but to create its own contents. The very nature of cognition is reversed.
