The American sociologist, Samuel Royce, after a careful study of American and European defective classes,[36] found that observation of the hereditary nature of pauperism which congenitally reverts into insanity, disease or crime, leaves no doubt but that pauperism is one of the worst forms of race deterioration, and that the paralysis of the human will and its energies is but the result of a fearful dissolution in progress. Extensive researches made by Charles S. Hoyt,[37] of the New York State Board of Charities (1874), into the origin of the defective classes of that state, show that the pauper, hysteric, epileptic, prostitute, criminal, born-blind, deaf-mute, paranoiac, recurrent lunatic and idiot were buds of the same tree of degenerate heredity. E. C. Spitzka,[38] basing his researches on the principles of Morel as expanded and critically applied by Meynert,[39] reached essentially the same results as also did Westphal, Krafft-Ebing, Grille, Kerlin, Axel Key, Magnan, Foville, Bjornstrom, Amadei, Schüle, Nicolson,[40] Tonnini, Tamburini, Verga, Tamassia, Kowalevsky, and it may be said the German Psychiatrical Society (which, by accepting a conception of the distortion of mental faculties otherwise seemingly high, based on brain deformity rather than disease, accepted the degeneracy doctrine of to-day). For several decades, moreover, the stigmata of degeneracy have appeared in French, German, Austrian, Russian, Italian, and Scandinavian court reports as evidence of hereditary defects. As often happens in science-- "Thought by thought is piled till some great truth Is loosened and the nations echo round."
