from the usual path of nature. However, he remained skeptical of over-simplistic versions of this concept: While commenting approvingly on the basic ideas of Cesare Lombroso's "criminal anthropology", he did not accept the popular idea of overt "stigmata of degeneration", by which individual persons could be identified as being "degenerated" simply by their physical appearance. While Kraepelin and his colleagues may not have focused on this, it did not stop others from advancing the converse idea. An early application of this theory was the Mental Deficiency Act supported by Winston Churchill in 1913. This entailed placing those deemed “idiots” into separate colonies, and included those who showed sign of a “degeneration”. While this did apply to those with mental disorders of a psychiatric nature, the execution was not always in the same vein, as some of the language was used to the those “morally weak”, or deemed “idiots”. The belief in the existence of degeneration helped foster a sense that a sense of negative energy was inexplicable and was there to find sources of “rot” in society. This forwarded the notion the idea that society was structured in a way that produced regression, an outcome of the “darker side of progress”. Those who had developed the label of "degenerate" as a means of qualifying difference in a negative manner could use the idea that this “darker side of progress” was inevitable by having the idea society could “rot". Considerations to the pervasiveness an allegedly superior condition were, during the nineteenth century, frighteningly reinforced the language and habits of destructive thinking. The "dark side" of progress The idea of progress was at once a social, political and scientific theory. The theory of evolution, as described in Darwin's The Origin of Species, provided for many social theorists the necessary scientific foundation for the idea of social and political progress. The terms evolution and progress were in fact often used interchangeably in the 19th century. The rapid industrial, political and economic progress in 19th-century Europe and North America was, however, paralleled by a sustained discussion about increasing rates of crime, insanity, vagrancy, prostitution, and so forth. Confronted with this apparent paradox, evolutionary scientists, criminal anthropologists and psychiatrists postulated that civilization and scientific progress could be a cause of physical and social pathology as much as a defense against it. This led to the emergence of a general theory of degeneration, never reduced to
