These proposals are biblically and historically monstrous, but Singer is a soft-spoken Princeton professor. Whittaker Chambers a half-century ago wrote that, "Man without God is a beast, and never more beastly than when he is most intelligent about his beastliness," but part of Singer's effectiveness in teaching "Practical Ethics" to Princeton undergraduates is that he does not come across personally as beastly.

 C.S. Lewis 61 years ago wrote "That Hideous Strength," a novel with villainous materialists employed by N.I.C.E. (the National Institute of Coordinated Experiments). Their offices were to be in a building that "would make quite a noticeable addition to the skyline of New York." But Singer sits in an unostentatious office at Princeton's Center for Human Values, which is housed in a small and homey grayish-green building with a front yard that slopes down the street. The center even has a pastoral-sounding address: 5 Ivy Lane.

 C.S. Lewis's N.I.C.E. leaders are totalitarian. They use media control and a police force to push opponents into submission. Singer says he's not totalitarian because he accepts debate and says that "people can draw the line anywhere." But, within Singerism, should they? He scorns attempts to set up standards of good and evil that go beyond utilitarianism, and hopes to convince people willingly to do it his way.

 The challenge for conservatives during the next several decades will be not only to win elections, but to win the intellectual battles.
