He considers the evolutionist doctrine to be a major philosophical and scientific error. Schumacher argues that the evolutionist doctrine starts with the perfectly reasonable explanation of change in living beings, and then jumps to using it as an explanation for the development of consciousness, self-awareness, language, social institutions and the origin of life itself. Schumacher points out that making this conceptual leap simply does not meet the standards of scientific rigor and the uncritical acceptance of this leap is, for Schumacher, completely unscientific.
The evolutionist doctrine makes a philosophical error in its leap from its rightful explanation of biological change to the development of consciousness, self-awareness, language, and the origin of life itself.
