Scotosis refers to the resulting form of pneumapathology, in which "the deformed sectors of the field acquire the status of true reality, while the sectors of true existence are eclipsed by the imagery of deformation" (Voegelin).
Now, it is the work of an instant for the leftist to dismiss the entire idea of scotosis, because if there is no objective reality, there can be no holes in it. Multiculturalists, for example, insists that no one's version of reality is any better or worse than anyone else's, and that there exists no standard to make such a determination anyway. Likewise moral relativism.
But ironically, if you should fail to acquiesce to this doctrine, you will find yourself being accused of having a gaping hole in your own sensibilities. Or in other words, if you imagine that your vision is superior -- that it has fewer holes than the other guy's -- then you are what is known as a fascist.
BTW, a commenter asked, "How does a scotoma relate to a mind parasite?" This is a good question, and there is no simple way to answer it, since there are different kinds of holes and parasites at different levels of the psyche, and the hole itself can take on the attributes of a parasite.
As I mentioned in a comment, it is literally a kind of "present absence," or perhaps "nameless dread." Its annoying child is anxiety, apprehension, foreboding, or heebie-jeebies. Without them there would probably be no such thing as ghost stories and the like, because we would have no subjective frame of reference.
How to summarize without getting too sidetracked?
First of all, bear in mind that what follows is a model, not the thing itself -- a useful way to organize and think about reality, analogous to, say, the theory of natural selection. No need to commit the fallacy of misplaced concreteness.
The psychoanalyst W.R. Bion developed a theory of thinking and knowing in which knowledge first arises "in primitive emotional experiences related to the absence of the object," i.e., the mother, or even prior to that, the subjective experience of the "good breast." Imagine an infant whose every need is met in a seamless and harmonious way. But under the best of circumstances, the baby will eventually have the disturbing experience of a lack, an absence of food, of comfort, of warmth, of emotional connection, of predictability, whatever.
Note that the infant has no concept of hunger, let alone the word. Rather, the absence -- hunger -- will be experienced as a presence within the field of awareness. Only much later will this experience acquire the name "hunger." And even then, for many people, emotional absence (alone-ness) easily translates to physical hunger; or hunger -- say, in an anorectic -- becomes a way to deny the need for others; for the anorectic, to be hungry is to maintain an omnipotent denial of dependence upon others.
Let's fast forward to adulthood. Take the example of love. In a certain sense, love is a name we give to an absence we feel at the center of our being. Orthoparadoxically, only the loveless -- those aware of the hole, and capable of tolerating it -- can both love and be truly grateful for the love received.
There are two common forms of psychopathology that revolve around this hole. On the one hand, there are people who have what is called borderline personality structure, who essentially cannot tolerate separation and therefore catastrophize it into abandonment. At the other end (but really, it's just an iteration of the same situation) are narcissistic personalities who cannot tolerate real intimacy, and who use and discard people without a backward glance.
As it so happens, borderline and narcissistic folks often get together, and that is when you see the sparks -- or dinner plates, or fists, or bullets -- fly.
A quintessential example is the insanely intense -- or intensely insane -- relationship between Frank Sinatra and Ava Gardner. It's been a long time, but I remember the film Who's Afraid of Virginia Woolf being a depressingly vivid depiction of the dynamic. In fact, some might ask of the Burton & Taylor performances: what acting?
A somewhat frivolous but illustrative example comes to mind. It must have been at least a decade ago, but I remember seeing Angelina Jolie being interviewed by Larry King, and revealing to him that she had suffered a kind of nervous breakdown -- a psychotic break -- when her then boyfriend Billy Bob Thornton had to absent himself in order to film a picture.
And now that I review her wikipedia page, I see that there is quite a bit of evidence of a primitive borderline personality (unless, of course, she just wishes to be known as a psycho). For example, for one of her weddings she wore a t-shirt with the groom's name written in her blood; she acknowledges her confused sexual identity (bisexuality); she impulsively married old Billy Bob, and sealed the deal by "wearing one another's blood in vials around their necks"; she and BB then abruptly separated -- as borderlines are wont to do -- "because overnight, we totally changed. I think one day we had just nothing in common."
That last quote is a giveaway, in that the "total change" of which she speaks is a result of flipping from one sub-personality to another. One side of the personality has a psychotic fear of abandonment, while the other can evacuate an intimate relationship with a chillingly instantaneous finality. If you are their unlucky therapist, you can go from Jesus to Hitler in under a second. In graduate school I learned the adage that one should never treat more than one borderline personality at a time, unless one is a masochist. Although I might make an exception for insanely wealthy celebrities who have a tendency to idealize.
Admittedly, if one is bored with life, a relationship with a borderline personality is going to spice things up. Let's just say they're on the intense side. In fact, I remember a headline on Drudge some time back, to the effect that Brad Pitt found life with Jennifer Aniston to be a bit of a snooze. Nowadays he probably has to rest -- as Big Joe Turner sang -- with "one one eye on my pistol / And the other eye on my trunk."
Rambling. I'm not sure that was helpful. Let's just say that there is and must be a genuine absence at the foundation of the personality, and that it is necessary to tolerate this absence in order to love or to know. And there is something known as the basic fault, which essentially results from the psychic hole being too vast to bridge or not being tolerated.
And of course, in the ultimate sense, we all have a "God-shaped hole" at the center of our being, and this is what Voegelin has in mind when he speaks of the "in-between" state that man inhabits here on earth and in time. Again, we symbolize this necessary hole Ø <---> O.
Let's get back on track. We're all familiar with Thomas Kuhn's idea of "paradigm shifts" in science, say, from Newtonian to quantum mechanics, or from the geocentric to the heliocentric theories of orbit.
But we all inhabit a much vaster paradigm, which we might call the "climate of opinion," or "temper of the times," or "liberal agenda." As Whitehead wrote in The S & M World, "Every philosophy is tinged with the colouring of some secret imaginative background, which never emerges explicitly into the trains of reasoning," and revolves around "intellectual positions which its exponents" do not "feel it necessary explicitly to defend."
For Voegelin, this system is the order; and naturally we want this microcosmic order to reflect the macrocosmic Order as much as possible. One thing we don't ever want to do is superimpose our own little order over the Order (which is again a kind of lunar eclipse, or the blocking of the central sun by means of lunacy, i.e., assault & moonbattery).
At no time in my life has the gulf separating the orders been more vast; for example,
--"You didn't build that!" vs. "And you built what exactly, aside from 10 trillion in debt?"
--"They gonna put y'all back in chains!" vs. "No, we actually want to deactivate that shock collar the Democratic party has around your neck."
--"If you don't spring for birth control for abortion activists, you hate women" vs. "Hey, we just want to stay out of your bedroom, and we certainly want to keep our hands off Sandra's Fluke."
--"You're anti-union" vs. "What kind of idiot is in favor of the collusion between elected officials and state employees to expand the size of government?"
--"Obama is a genius and an evolutionary lightbringer" vs. "Obama is an arrested undergrad who unfortunately took his professors seriously."
--"I need to tell a better story" vs "Don't underestimate yourself. It's not possible to be better bullshit artist."
--"Let's party now and send the bill to our great grandchildren" vs. "THERE. IS. NO. FUCKING. MONEY!"; etc.
In each case, the president and his sympathizers either see something that isn't there, or don't see something that is. Absent presences and present absences.
[F]or we all have had our encounters with men who, sternly rejecting their humanity, insist on being modern men and, in so-called discussion, try to bury us under the rhetoric of deformed existence. --Voegelin
