Biology and Philosophy 5 (4):451-457 (1990)

Richards's theory, then, fails on three counts. By illegitimately importing a premise from outside of the theory of evolution in order to construct a valid argument, Richards has failed to achieve his objective of deriving a moral theory exclusively from biological facts. By sliding from a causal use of “ought” to a moral one, Richards commits the fallacy of ambiguity. And by insisting that action from the motive of altruism is moral while claiming that an ethical theory which justifies Hitler's camps must be judged false, Richards has falsified his own ethical theory
