Andrew Sullivan opposes fundamentalisms of all kinds, including Christian fundamentalism, presumably because fundamentalists tend to be absolutists. This is a mindset Andrew finds repugnant:
There is an absolutist, fundamentalist, authoritarian tendency in all monotheisms. Right now, that tendency is ascendant in all the major faiths - but it has become particularly dangerous in Islam. The problem is not religion as such, or faith as such. The problem is fundamentalism, and its certitude. There is another kind of religious faith - more rooted in doubt, more subject to humility in front of the ineffability of an ultimately unknowable God, less abstract, more sacramental. That kind of religion, which sees the different faith of others as an invitation rather than a threat, is compatible with liberal democracy. And it's that faith we have to recover and reinvigorate if we are to combat the excesses of both Islamic and Christian fundamentalists, and their political ambitions.
Very well, certitude is bad, humility is good. No one should ever believe that they are right absolutely and that anything or anyone is always wrong absolutely. But then how's this for absolutism?
In this inevitably emotional debate, perhaps the greatest failing of those of us who have been arguing against all torture and "cruel, inhuman, and degrading treatment" of detainees is that we have assumed the reasons why torture is always a moral evil, rather than explicating them. But, when you fully ponder them, I think it becomes clearer why ... torture, in any form and under any circumstances, is both antithetical to the most basic principles for which the United States stands and a profound impediment to winning a wider war that we cannot afford to lose.
A little side trip to the link reveals that these words were written by ... Andrew Sullivan. Torture is absolutely wrong, Andrew avers. Evidently, whether absolutism is an evil depends upon whose absolutes are under scrutiny. Absolutism is bad when it's a phenomenon displayed by Christian conservatives, but it's entirely appropriate, and indeed morally exalted, when the absolutes are such as sophisticates like Andrew embrace.
