Maybe one of the best, simple presentations of fallacies in dumb scientism about ethics (the scientism of extreme simpletons like Sam Harris, Michael Shermer, etc)

Phillip Kitcher's 1994 paper dismantling E.O. Wilson's program of biologicizing ethics: Just a neat presentation of the ancient arguments that defeat dumb scientistic, logic-denying positions on ethics
