 Herbert Spencer (1820–1903) is typically, though quite wrongly, considered a coarse social Darwinist. After all, Spencer, and not Darwin, coined the infamous expression “survival of the fittest”, leading G. E. Moore to conclude erroneously in Principia Ethica (1903) that Spencer committed the naturalistic fallacy. According to Moore, Spencer’s practical reasoning was deeply flawed insofar as he purportedly conflated mere survivability (a natural property) with goodness itself (a non-natural property).
