Our age has no shortage of curious features, but for me, at least, one of the oddest is the way that so many people these days don’t seem to be able to think through the consequences of their own beliefs. Pick an ideology, any ideology, straight across the spectrum from the most devoutly religious to the most stridently secular, and you can count on finding a bumper crop of people who claim to hold that set of beliefs, and recite them with all the uncomprehending enthusiasm of a well-trained mynah bird, but haven’t noticed that those beliefs contradict other beliefs they claim to hold with equal devotion.
I’m not talking here about ordinary hypocrisy. The hypocrites we have with us always; our species being what it is, plenty of people have always seen the advantages of saying one thing and doing another. No, what I have in mind is saying one thing and saying another, without ever noticing that if one of those statements is true, the other by definition has to be false. My readers may recall the way that cowboy-hatted heavies in old Westerns used to say to each other, “This town ain’t big enough for the two of us;” there are plenty of ideas and beliefs that are like that, but too many modern minds resemble nothing so much as an OK Corral where the gunfight never happens.
An example that I’ve satirized in an earlier post here is the bizarre way that so many people on the rightward end of the US political landscape these days claim to be, at one and the same time, devout Christians and fervid adherents of Ayn Rand’s violently atheist and anti-Christian ideology.  The difficulty here, of course, is that Jesus tells his followers to humble themselves before God and help the poor, while Rand told hers to hate God, wallow in fantasies of their own superiority, and kick the poor into the nearest available gutter. There’s quite precisely no common ground between the two belief systems, and yet self-proclaimed Christians who spout Rand’s turgid drivel at every opportunity make up a significant fraction of the Republican Party just now.
Still, it’s only fair to point out that this sort of weird disconnect is far from unique to religious people, or for that matter to Republicans. One of the places it crops up most often nowadays is the remarkable unwillingness of people who say they accept Darwin’s theory of evolution to think through what that theory implies about the limits of human intelligence.
