In the 1970s, or even the 1990s, it was possible to think religion had been declawed, and that further challenges to religious philosophies, institutions, and leaders were unnecessary. On this view, all the hard work had been done, and religion was withering away after the scientific revolution, the Enlightenment, Darwin, and the social iconoclasm of the 1960s. Against that background, it became taboo to criticise religion in the public sphere; it was widely assumed that religion was retreating, in any event, and didn’t need to be fought anymore. Attacks on people’s “deeply-held beliefs” even smacked a little of cultural imperialism.

In the academy, bright minds in philosophy turned to other topics. Bright young atheists and sceptics were certainly not steered into philosophy of religion, which looked like an intellectual dead end.

But the situation now looks very different, even in the supposedly enlightened nations of the West. For a start, a revived Christian philosophy is well entrenched within Anglo-American philosophy of religion. More importantly, perhaps, religious organisations and leaders continue to exert social power. All too often, they seek to control how we plan and run our lives, including choices about how we die. At various times, religious lobbies have opposed a vast range of beneficial, or at least essentially harmless, activities and innovations. Even now, one religion or another opposes abortion rights; most contraceptive technologies; stem-cell and therapeutic cloning research; physician-assisted suicide; and a wide range of sexual conduct involving consenting adults. We still see intense activism from the religious lobbies of all Western democracies, and even in relatively secular countries, such as the UK and Australia, governments pander blatantly to Christian moral concerns.

The situation is far worse in the US, where religious conservatives regrouped with dramatic success during the 1970s and 1980s, establishing well-financed networks, think tanks, and even their own so-called universities. Slick attempts are made to undermine public trust in science where it contradicts the literal Genesis narrative; a rampant dominionist movement wants to establish an American theocracy; the recent Bush administration took the country some considerable way down that path; and the election of a relatively liberal president has produced hysteria on the religious right (polling shows that many American conservatives now believe that Barack Obama is the Antichrist). American religiosity is real, and there is nothing subtle or liberal-minded about its most popular forms.
