oxygen, but [we do] not invoke divine intervention to explain the process ... thermodynamics offers nothing to dampen our confidence in Darwinism. Moral implications Other common objections to evolution allege that evolution leads to objectionable results, such as eugenics and Nazi racial theory. It is argued that the teaching of evolution degrades values, undermines morals, and fosters irreligion or atheism. These may be considered appeals to consequences (a form of logical fallacy), as the potential ramifications of belief in evolutionary theory have nothing to do with its truth. Humans as animals In biological classification humans are animals, a basic point which has been known for more than 2,000 years. Aristotle already described man as a political animal and Porphyry defined man as a rational animal, a definition accepted by the Scholastic philosophers in the Middle Ages. The creationist J. Rendle-Short asserted in Creation magazine that if people are taught evolution they can be expected to behave like animals: since animals behave in all sorts of different ways, this is meaningless. In evolutionary terms, humans are able to acquire knowledge and change their behaviour to meet social standards, so humans behave in the manner of other humans. Social effects In 1917, Vernon Kellogg published Headquarters Nights: A Record of Conversations and Experiences at the Headquarters of the German Army in France and Belgium, which asserted that German intellectuals were totally committed to might-makes-right due to "whole-hearted acceptance of the worst of Neo-Darwinism, the Allmacht of natural selection applied rigorously to human life and society and Kultur." This strongly influenced the politician William Jennings Bryan, who saw Darwinism as a moral threat to America and campaigned against evolutionary theory; his campaign culminated in the Scopes Trial, which effectively prevented teaching of evolution in most public schools until the 1960s. R. Albert Mohler, Jr., president of the Southern Baptist Theological Seminary in Louisville, Kentucky, wrote August 8, 2005, in NPR's Taking Issue essay series, that "Debates over education, abortion, environmentalism, homosexuality and a host of other issues are really debates about the origin — and thus the meaning — of human life. ...evolutionary theory stands at the base of moral relativism and the rejection of traditional morality." Henry M. Morris, engineering professor and founder of the Creation Research Society and the Institute of Creation Research, claims that evolution was part of a pagan religion that emerged after the Tower of Babel, was part
