The only thing Columbus discovered was that he was lost! -- Wyndom Earle
Since Ron Moore and colleagues sank my Battlestar, the only show I've cared about is Lost. As the former demonstrated, TV is determined by its own law of entropy, where any show gets worse in direct proportion to the length of time it's on times the structural quality (plot, characters, diegesis, etc.) that the creators initially developed. Clearly, BSG went on for about 2 years longer than the initial fund of creativity allowed. Its keg was all but tapped by the beginning of the third season. Given its tenuous beginning, Moore probably thought his show wouldn't make it much past the mini-series, hoping that he'd at least have one of those cult-celebrated shows that could've been. On the other side of the coin, TV executives don't much care about quality, but about how long they can wring some advertising dollars out of the shows they're broadcasting. As such, they are creatures of chaos, encouraging the steady dissolution of the creative order; they are, in a word, demonic. It's the nature of the beast that creators have to get in bed with these incubi to give birth to a TV show. This Faustian dialectic requires as much blind faith from the creators as it does money being thrown about by investors. Little wonder, then, why so many SF-fantasy shows are predisposed to defending faith over reason. As articles of faith in the face of overwhelming odds, they came into being as the result of big, dumb chance.
A classic example is X-Files, which burned out after the third season and whose endings justified every ludicrous theory the conspiracist Agent Mulder came up with. After a few years of this, the skepticism of Agent Scully's ratiocinations came across as implausible, or just plain dumb. Faith in something that's demonstratively true isn't really faith; it's empirical knowledge. Contrary to some interpretations, X-Files didn't really analyze the role of faith, so much as side-step it by making the supernatural natural. You'd be one stupid hobbit to doubt magic in Middle-Earth. The hero in an absurdist universe can either fight it like Agent 6 did in The Prisoner, or just embrace it like Maxwell Smart in Get Smart. On the former journey -- Kafkaesque in its structure -- lies madness, cancellation and no end to the story, much like what waits for the rationalist in the real world; on the latter, you get a better chance at a few more seasons, but, like a business going public and expanding, the product begins to feel like a cheap imitation (just look at X-Files).
Contrariwise, David Lynch and Mark Frost built the possibility for endless expansion into Twin Peaks with the mystery of Laura Palmer's murder -- what Lynch has called "the golden goose." They intended to keep it ongoing indefinitely while exploring the epiphenomenal mysteries arising from the central investigation. ABC felt that endless mystery would tax the faith of viewers, and "asked" the creators to wrap up the Laura storyline in the second season. The end of that mystery wasn't all that killed the show's élan: both Frost and Lynch went away to work on other projects, turning the reins over to a bunch of cheap Lynch clones, resulting in a whole lot of James and Lucy. It was with the return of Frost that the show began to regain some sense of direction, but more along the lines of the classic good versus evil struggle to which Nochimson alludes in the above quote. Agent Cooper now had a Moriarty, Wyndom Earle, a damsel in distress, Annie, and there was a white lodge to go along with the black one -- tropes that a Jungian once called archetypes, but are now known as clichés. Nochimson is herself a Jungian feminist who sees Cooper as a hero-seeker, a protagonist who leaves himself open to questions, tapping into the universal unconscious, rather than one who is out to conquer the Other. Openness, you see, is the province of universal femininty -- think the woman's classic coital role ('classic' should here be read as another synonym for 'cliché', or 'stereotype'). Reason is phallic, controlling, penetrating, and thusly the province of masculinity.
Despite the reductionistic men-are-from-Mars-women-from-Venus rhetoric, Nochimson's book gets it right that Lynch isn't much of an us-versus-them sort of narrator. As becomes increasingly evident from Blue Velvet to Inland Empire, all of his protagonists possess a Hermann Hesse-duality that drives the narrative more than some external battle with another. However, Cooper is his purest hero, only shown to face his dark side when Lynch returned for season 2's finale. By listening to his dreams and going with his occult intuition, Cooper might be considered a man of faith, albeit one who doesn't put all his eggs in one basket. (These eggs aren't of the hysterical kind, though.) But he was until the final episode, and against Nochimson's reading, always in control. He asked the right questions and proffered the best hypotheses again and again. I'd say, given the preternatural realm of Twin Peaks, Cooper belongs philosophically with his cohort Agent Mulder to Noam Chomsky's brand of rationalism. ("Mulder" even pops up in Twin Peaks as an FBI investigator in drag, an agent of scientifico-rationalism mocking the identity politics inherent in Nochimson's account.)
Against the bottom-feeding positivism of behaviorism that was dominant back in the 50s, Chomsky countered that unobservable mental models (the a priori, or given) were necessary to understand linguistic behavior. Scientific discovery, like language learning, is guided by models, where one has an initial theory that undergoes modification as experience dictates (I speak loosely here, so see these entries on Universal Grammar and Modularity if you're curious). If the data is consistent with the theoretical model, no change is necessary; it is, for all intents and purposes, rational knowledge. Mulder and Cooper's seemingly outlandish theories might not work in our world, but they tended to be confirmed by (were consistent with their experiences in) their own diegeses. Their faith is more analogous to David Hume believing that one billiard ball will move when struck by another, i.e., it always had in the past (as far as he knew).
