Psychological denial is a defense mechanism that is used by everyone at different times in their life to cope with an unacceptable reality. It becomes pathological when it persists for more than a brief time. Denial can either allows the user to come to grips with the pain by temporarily modulating it; or it can usher the user into fantasyland.
(h/t Dr. Sanity)
Here are some recent examples of the fantasyland variety:
Sometimes, the only way that the denial of reality can be maintained, and the fantasy upheld, is
through self-delusion....
Engaging in "self-delusion" is the act of deceiving one's self about some aspect of reality; i.e., it is a form of psychological denial.
- by using projection some very violent and angry people are able to convince themselves that they are working for peace and harmony.
- by using delusional projection some religious fanatics who behead innocent people are able to convince themselves that they are pure and holy, while" infidels" like Jews are monsters who "eat babies" and decend from "pigs and monkeys"
- by using displacement, some people are able to convince themselves that there is a devious plan to imminently replace our secular government with a Christian theocracy; while they are singularly unconcerned about religious fanatics actively waging war on the U.S. and the rest of the world trying to institute an Islamic theocracy.
- by using fantasy some people are able to convince themselves that these particular religious fanatics are reasonable and sensible people, amenable to negotiation and moderation.
- by using denial some people are able to convince themselves that Obama's economic policies are creating jobs and improving the economy.
- by using repression some people would like to eliminate all personal feelings about 9/11 and wipe it from the American collective consciousness; thus supporting the building of a mosque at Ground Zero while we are still in a protracted war with Islamic fundamentalists.
When dealing with well-defended people like this, one of the refrains commonly heard when you point out their defense to them, is that it is not they who are in denial about reality--it is you! It is not they who are projecting, it is you! It is not they who fail to see the danger, it is you!
For them it is simply a matter of opinion whether or not a person is out of touch with reality; and their opinion is just as good as yours, thank you very much.
But let's examine that interesting perspective (usually they convey it with a sneer, as in: "That's just your opinion.")
Probably the first prerequisite for accusing someone of engaging in self-delusion is that one must accept that there is an objective reality, external and independent to one's self; one's beliefs or one's emotions/feelings. Without such a fundamental epistomological foundation, it is completely meaningless to accuse anyone of self-delusion, althought postmodern intellectuals do it all the time.
For the record, self-delusion is an equal opportunity political defense. Both sides of the political spectrum are able to delude themselves fairly easily when the occasion demands it. But I am always impressed at the pervasive self-delusion that is the hallmark of modern leftist thought. No amount of reality is able to touch it.
As they wallow in their preferred form of social subjectivism, it is perfectly "reasonable" (if that is the word) from their perspective to impute delusion to others--even if every time they do so, they effectively demonstrate the invalidity of their own philosophy. That is why it is so amusing to observe their appropriation of the term "reality-based community" -- when they don't believe in any reality except for their own emotions!
The truth that threatens their fantasyland is that there is a world that exists outside their heads and outside their emotions; and that the entire purpose of reason --which they reject in favor of feelings --is about understanding that world.
Social subjectivism posits that our minds are disconnected from reality to begin with. How then is it possible for them to accuse anyone of "self-delusion"? One simply has a differing POV that is by their definition as real and true as anyone else's.
After all, that is the basis of the multiculturalism and the "politically correct" relativism that is persistantly foisted on the public.
You see, progressives feel that they can get away with their interpretations simply because they don't have to deal with external reality --if they feel it, it must be true! QED. The actual worsening of the economy under their watch despite driving the country into unbelievable amounts of debt is not something they care to think about. Instead, Nobel Prize winning economic morons like Paul Krugman explain the failures away by saying that the stimulous wasn't big enough!

When you live in a world where objective reality is unacknowledged, is it any wonder that from your perspective no one can every prove that what you feel is true, isn't really true? That is why the same distortions and creative fabrications resurface time after time in political discussions these days. The entire "the economy is all Bush's fault" for example. No matter how many times this is debunked, (or, I suspect, no matter how many years into Obamanomics we are) it will be recycled by the reality-based, or rather, the reality-deprived community.
To them, Obama may be fading as a leftist messianic superstar, but only because he is not going far enough in shoving their policies down America's throat. Certainly not because those polices don't work and never have worked! Let's see what happens when America thoroughly rejects their ideology in November.... I predict that the left will not be abashed; nor will they even consider re-examining their political --let alone their philosophical premises. No, they will whine loudly; scream hysterically; become agressive and probably violent, and insist that their policies were sabotoged by the likes of you and me (i.e., racist bigots who are homophobic, Islamophobic, and sexist to boot); that we are the ones who will not face reality, and so on and so forth ad infinitum.
