X. Philosophy of Freedom and Monism

Second Addition to the Revised Edition, 1918: On page 34, materialism was referred to. I am well aware that there are thinkers like the above-mentioned Th. Ziehen, who do not in the least consider themselves materialists, but who must nevertheless be described as such from the point of view expressed in this book. It is not a matter that someone says that for him the world is not restricted to merely material existence and therefore he is not a materialist. It is a matter of whether or not he develops concepts which are applicable only to a material existence. One who says: “Our conduct, like our thinking, is necessitated,” expresses a concept applicable only to material processes, but applicable neither to actions nor to existence; and if he thinks his concepts through, he will have to think materialistically. That he does not do this is only the outcome of that inconsistency which is so often the result of a thinking not carried through.—One often hears it said nowadays that the materialism of the nineteenth century no longer plays a part in science. But in reality this is not so at all. It is only that at present it is often not noticed that no other ideas are available than those which can be applied only to something material. This veils present day materialism, whereas in the second half of the nineteenth century it was plain for all to see. And present day veiled materialism is no less intolerant of a view that grasps the world spiritually than was the openly-admitted materialism of the last century. However, it deceives many who believe they must reject a comprehension of the world which includes spirit, because after all, the natural scientific comprehension of the world “has long ago abandoned materialism.”
