peculiar set of circumstances—political, social, and ideological—when religion becomes fused with violent expressions of social aspirations, personal pride, and movements for political change". and that it is unreasonable to attempt to differentiate "religious violence" and "secular violence" as separate categories. While others assert religion is not inherently violent and while the two are compatible they are not essential and that religious violence can be compared with non-religious violence. C. S. Lewis suggests that all religions by definition involve faith, or a belief in concepts that cannot be proven or disproven by the sciences. Not all religious people subscribe to the idea that religion and science are mutually exclusive (non-overlapping magisteria) as do some atheists including Stephen Jay Gould. Biologist Richard Dawkins has said that religious practitioners often do not believe in the view of non-overlapping magisteria. According to a survey most religious groups in the United States have no general epistemological conflict with science or with the seeking out of scientific knowledge even if there are epistemic or moral conflicts with their faith. Strict creationists tend to have very favorable views on many of the different sciences. A study on a national sample of United States college students found that the majority of undergraduates in both the natural and social sciences do not see conflict between science and religion. Cross-national studies polled from 1981 to 2001 on views of science and religion have noted that countries with higher religiosity have stronger trust in science. Morality Richard Dawkins contends that theistic religions devalue human compassion and morality. In his view, the Bible contains many injunctions against following one's conscience over scripture and positive actions are supposed to originate not from compassion, but from the fear of punishment. Albert Einstein stated that no religious basis is needed in order to display ethical behavior. Children In the 19th century, philosopher Arthur Schopenhauer argued that teaching some ideas to children at a young age could foster resistance to doubting those ideas later on. Some clerics of Islam have permitted the child marriage of older men to girls as young as 9 years of age. Baptist pastor Jerry Vines denounced Mohammed as a pedophile for marrying and having had sex with a nine-year-old. For example, one organisation cites the case of a 10-year-old girl who was forced to marry and was raped in Yemen (Nujood Ali), a 13-year-old Yemeni girl dying of internal bleeding three
