I grew up with a literalist/fundamentalist version of Christianity, and when I discovered the atheistic/materialistic/scientific worldview it came as a shock - I implanted on it immediately, the world made much more sense almost overnight and I lost all interest in anything remotely spiritual. Later on I discovered the rest of religion, and the intellectual shock was similar, but not much else changed. I still find the purely materialistic worldview perfectly satisfactory and I fully expect that it will continue to conquer everything in its path, up to and beyond the mind-body problem, but until then, and maybe even after then, I have no problem characterizing my lack of personal commitment to faith, God, or the spiritual as purely aesthetic. I can appreciate, to some extent, why other people prefer to believe it, and I can appreciate, to some extent, why many people on each side either can't or won't believe that sensible people could hold such obviously stupid and wrong beliefs. Every time I start to think that the religious have a monopoly on lack of curiosity, some atheist pops up and makes a spectacle of their own righteous single-mindedness. I prefer to cultivate a certain amount of genuine curiosity about, and appreciation for, the aesthetic preferences of the other 80% of the human race.
