Harris follows this with a brief survey of Christianity down the ages, examining the Inquisition and persecutions of witches and Jews. He contends that, far from being an aberration, the torture of heretics was a logical expression of Christian doctrine – one which, he says, was clearly justified by men such as Saint Augustine. Going still further, Harris sees the Holocaust as essentially drawing its inspiration from historical Christian anti-Semitism. "Knowingly or not," he says, "the Nazis were agents of religion." Among the controversial aspects of The End of Faith is an uncompromising assessment and criticism of Islamism, which Harris describes as being a "cult of death." He infers a clear link between Islamic teaching and terrorist atrocities such as 9/11, a notion he supports with quotations from the Koran that call for the use of violence. He also presents data from the Pew Research Center, purporting to show that significant percentages of Muslims worldwide would justify suicide bombing as a legitimate tactic. In an attack on what he terms "leftist unreason," Harris criticises Noam Chomsky among others for, in his view, displaying an illogical willingness to lay the entire blame for such attitudes upon U.S. foreign policy. However, Harris also critiques the role of the Christian right in the United States, in influencing such areas as drug policies, embryonic stem cell research, and AIDS prevention in the developing world. In what he sees as a steady drift towards theocracy, Harris strongly criticises leading figures from both the legislature and the judiciary for what he perceives as an unabashed failure to separate church and state in their various domains. "Not only do we still eat the offal of the ancient world," he asserts, "we are positively smug about it." Next, Harris goes on to outline what he terms a "science of good and evil" – a rational approach to ethics, which he claims must necessarily be predicated upon questions of human happiness and suffering. He talks about the need to sustain "moral communities," a venture in which he feels that the separate religious moral identities of the "saved" and the "damned" can play no part. But Harris is critical of the stance of moral relativism, and also of what he calls "the false choice of pacifism." In another controversial passage, he compares the ethical questions raised by collateral damage and judicial torture during war. He concludes that collateral damage is
