by some as the inevitable "disappearance" of "the weaker races... before the stronger" not so much "through the effects of ... our vices upon them" as "what may be called the virtues of our civilisation." Winston Churchill, a political proponent of eugenics, maintained that if fewer 'feebleminded' individuals were born, less crime would take place. Proponents Herbert Spencer's ideas, like those of evolutionary progressivism, stemmed from his reading of Thomas Malthus, and his later theories were influenced by those of Darwin. However, Spencer's major work, Progress: Its Law and Cause (1857), was released two years before the publication of Darwin's On the Origin of Species, and First Principles was printed in 1860. In The Social Organism (1860), Spencer compares society to a living organism and argues that, just as biological organisms evolve through natural selection, society evolves and increases in complexity through analogous processes. In many ways, Spencer's theory of cosmic evolution has much more in common with the works of Lamarck and Auguste Comte's positivism than with Darwin's. Jeff Riggenbach argues that Spencer's view was that culture and education made a sort of Lamarckism possible and notes that Herbert Spencer was a proponent of private charity. However, the legacy of his social Darwinism was less than charitable. Spencer's work also served to renew interest in the work of Malthus. While Malthus's work does not itself qualify as social Darwinism, his 1798 work An Essay on the Principle of Population, was incredibly popular and widely read by social Darwinists. In that book, for example, the author argued that as an increasing population would normally outgrow its food supply, this would result in the starvation of the weakest and a Malthusian catastrophe. According to Michael Ruse, Darwin read Malthus' famous Essay on a Principle of Population in 1838, four years after Malthus' death. Malthus himself anticipated the social Darwinists in suggesting that charity could exacerbate social problems. Another of these social interpretations of Darwin's biological views, later known as eugenics, was put forth by Darwin's cousin, Francis Galton, in 1865 and 1869. Galton argued that just as physical traits were clearly inherited among generations of people, the same could be said for mental qualities (genius and talent). Galton argued that social morals needed to change so that heredity was a conscious decision, to avoid both the over-breeding by less fit members of society and the under-breeding of the more fit ones.
