III. Why the Desire for Knowledge is Fundamental

A curious variant of Idealism is to be found in the theory which F. A. Lange has put forward in his widely read History of Materialism. He holds that the Materialists are quite right in declaring all phenomena, including our thought, to be the product of purely material processes, but, in turn, Matter and its processes are for him themselves the product of our thinking. “The senses give us only the effects of things, not true copies, much less the things themselves. But among these mere effects we must include the senses themselves together with the brain and the molecular vibrations which we assume to go on there.” That is, our thinking is produced by the material processes, and these by our thinking. Lange's philosophy is thus nothing more than the philosophical analogon of the story of honest Baron Munchhausen, who holds himself up in the air by his own pigtail.
