Yep, that's what I said. I get tired of people suggesting that there is. It's ALWAYS, not just usually, but ALWAYS the case of a person suggesting this who doesn't understand how ultimate beliefs work.
The problem is a worldview conflict. The problem is in your necessary beliefs. Cognitive dissonance takes place when you hold secondary beliefs that are in conflict with your necessary beliefs (usually ingrained within you from early childhood on) concerning the nature of reality and what authorities have the ability to interpret that reality (which will also be determined by your ultimate beliefs concerning reality).
What happens is that most people, especially Westerners, hold all sorts of conflicting ideas because we pick up ideas from here and there from various places. This is even worse in a pluralistic, global atmosphere, where ideas are adopted as you were just looking for things that struck an emotional cord or thought were interesting, but have now treated ideas like an all-you-can-eat Vegas buffet. Forget the fact that chinese noodles don't really go with hot dogs in beans. Pile it on.
The problem, of course, usually occurs when one is confronted with his inconsistencies. This often happens in school or by reading a particular book or hearing lectures on the internet. It can also just occur by one's own growth in thinking about what he believes. This is where cognitive dissonance kicks in.
The individual now realizes that those secondary beliefs that are in conflict with his ultimate beliefs no longer make sense in light of them. He often doesn't realize that is what he is doing. Instead, he's largely ignorant of his ultimate beliefs and their absolute determination of what he views as viable in light of them. Instead, he'll often just pit secondary beliefs that stem from those ultimate beliefs that he now views as absolutely true against other secondary beliefs that do not stem from those ultimate beliefs, or are not compatible with them, in order to refute the validity of those secondary beliefs that cannot be true if his other set of secondary beliefs are true.
This happens a lot in religious circles in the West, simply because our primary religion is a secular humanism based in ultimate beliefs that are largely naturalistic (atheism, agnosticism, deism). That's why the academy (the Western tribal prophet) has convinced everyone that the closer your conclusions follow a naturalistic train of thought, the more it is you are doing true scholarship, coming to the objective truth of a matter (as if holding a legion of beliefs based upon an ultimate belief that is self refuting somehow gets you closer to truth, but it does get you closer to academic excellence in the cultic Western mind).
What then occurs is doubt and unbelief in those secondary beliefs. The individual, again, thinks that he is coming to see reality more clearly and that what he believed before can no longer be sustained within the framework of self evident truths (again, truths that are self-evident as long as you assume the ultimate belief system that supports them, but he doesn't usually realize this).
What you end up with is a bunch of people whining about how they need to reconfigure Christianity to make sense in light of those "truths," which is really nothing more than turning Christianity into a spiritual form of secular humanism that includes some sort of belief in a Jesus that is more accommodating to his ultimate beliefs that are largely in conflict with those the Bible would have given him.
This is what occurs in liberalism. This is why so many atheists are being made in our culture. I say this from an intellectual standpoint. The Bible is clear that God gives people who think they are wise in their worldviews, wiser than God's Word, to the foolishness of them, and hence, their minds are darkened. But from an intellectual standpoint, if one truly understands the nature of ultimate beliefs, he realizes that doubt and unbelief are not intellectual problems. They are epistemic problems. Ergo, there is no intellectual problem for Christianity. There is only an epistemic problem that will continue to create false Christians when they never realize that their beliefs and practices are based upon a belief system that is completely hostile toward Christianity, or apostates who think that they have jettisoned orthodox Christianity because they can't make sense of it as a viable belief system within the framework of what they "know to be true."
It's sad really. Not because they choose a different path, but because they don't know why they've chosen it. Indeed, they've been so deceived that they now think they could choose no other. In this way, their ultimate beliefs have not given them greater academic freedom, but an enslavement that has cut off all other choices but that which is either incoherent and mystical when they want to hang onto some form of Christianity or complete unbelief when they do not.
