The course of evolution of Feuerbach is that of a Hegelian — a never quite orthodox Hegelian, it is true — into a materialist; an evolution which at a definite stage necessitates a complete rupture with the idealist system of his predecessor. With irresistible force, Feuerbach is finally driven to the realisation that the Hegelian premundane existence of the “absolute idea”, the “pre-existence of the logical categories” before the world existed, is nothing more than the fantastic survival of the belief in the existence of an extra-mundane creator; that the material, sensuously perceptible world to which we ourselves belong is the only reality; and that our consciousness and thinking, however supra-sensuous they may seem, are the product of a material, bodily organ, the brain. Matter is not a product of mind, but mind itself is merely the highest product of matter. This is, of course, pure materialism. But, having got so far, Feuerbach stops short. He cannot overcome the customary philosophical prejudice, prejudice not against the thing but against the name materialism. He says:
‘To me materialism is the foundation of the edifice of human essence and knowledge; but to me it is not what it is to the physiologist, to the natural scientists in the narrower sense, for example, to Moleschott, and necessarily is from their standpoint and profession, namely, the edifice itself. Backwards I fully agree with the materialists; but not forwards.’
