The cult film Primer is a knot made out of $7000 worth of celluloid. It is a twisted and convoluted film, a recursive puzzle, that appears as a jumble precisely because it follows its own rules so meticulously. Carruth’s film spawned a slew of web forum debates and sites dedicated to various theories as fans tried to work out just what had happened in the film, and just what it was that Carruth’s time travelers, Abe and Aaron, together, had done. If you Google the movie you can find a book turned into a backwards blog called The Primer Universe where all the questions raised by the movie are, apparently, put to rest. If nothing else, the site claims to have nailed down the plot and/or the time line. However, one question that the Primer Universe site leaves unanswered is why it is that Carruth’s time travelers lose their ability to write properly. Why does their handwriting deteriorate after they’ve traveled in time?

Abe: What’s wrong with our hands? Aaron: [has his arms tightly wrapped around his chest, his hands tight under his armpits] What do you mean? Abe: [almost shouting] Why can’t we write like normal people? Aaron: [quietly] I don’t know. I can see the letters… I know what they should look like, I just can’t get my hand to make them easily. [Abe is rocking back and forth against the desk; Aaron is quietly jittering] Abe: Try comparing it to your left hand. Aaron: It’s almost the same.

There are a few theories floating around trying to explain this. One philosophy webpage suggests that the time travelers have been reversed by the process of time travel and that they actually are writing with what had been their left hands in the previous timeline. But if that were the case wouldn’t writing with what is their left hands in the new timeline fix the problem? Others argue that it is simply a matter of the machine inflicting brain damage on the time travelers, but if this is so it is a peculiarly specific kind of brain damage. Why would their ability to write letters be damaged but their speech centers be left completely intact? Why wouldn’t a time machine affect their memory?

Consider this: Their time machine first untethers the weeble-wobbles Abe and Aaron place inside it and then untethers Abe and Aaron themselves. The two of them oscillate between point A and point B inside the box, and like the weeble-wobbles before them, they get stuck in the median. They become unhitched from the normal flow of things before they are released.

Abe: Everything we’re putting in that box becomes ungrounded. And I don’t mean grounded to the earth, I mean untethered.

Now, I want to tell you my theory of why it is that the time travelers are losing their ability to write, but in order to do that I have to tell you about Hegel’s concept of the Negation of the Negation and an episode of Columbo first.

In Hegel’s Phenomenology of Spirit there is a procedure to which Hegel subjects every positive proposition, a procedure called dissolution. This process, or procedure, of dissolution doesn’t belong to Hegel alone. In fact, the Phenomenology seems to be Hegel’s attempt to demonstrate how all the philosophers who came before him were correct and how understanding just how these other philosophers were correct required us to discover this procedure of dissolution. As each idea falls apart we’re led from one idea to the next.

Here’s a quote from Hegel that I’ve lifted from Wikipedia: “Something becomes its other; this other is itself something; therefore it likewise becomes an other, and so on ad infinitum.” (Hegel, Georg Wilhelm Friedrich. 1874. The Logic. Encyclopedia of the Philosophical Sciences. 2nd Edition. London: Oxford University Press.)

So, let me explain this, in the Columbo episode “A Tribute to the Commodore” the owner of a sailboat company is murdered and it is Columbo’s job to find the killer amongst the socialites and hangers-on that had glommed onto the Commodore and his fortune while the Commodore was alive. Columbo particularly suspects the Commodore’s son-in-law and when Columbo expresses his suspicions the son-in-law objects:

“It couldn’t have been me. I left the yacht club at 12:45 aM. You can check with security to find out the time when I left.”

To this Columbo says that the son-in-law’s alibi is the very reason he (the son-in-law) is the main suspect. “I asked myself, right from the beginning, why you would ask the guard for the time when you had such an expensive watch and his was just dimestore brand? Why did you ask him unless you wanted the guard to note the time?” Columbo asks.

No matter how clever the criminal is, every act the criminal undertakes to cover up the trail that leads to his guilt always creates another new trail. And what Hegel would say this means is that the criminal’s guilt always has to manifest as a cover-up. Certainly that’s how murder works on Columbo.

Aaron: We’re above the law? Abe: Absolutely, well above it.

Here’s my theory about why the time travelers can’t write. The more they recursively travel back, the more they try to rewrite their lives, the more obvious their own signature on reality becomes. They are nothing but the scenes written and rewritten, and as they write and rewrite the less capable they become. To put this another way, they start to become aware of how reality is structured as a cover-up, of how there is no original and substantial reality that is grounding their attempts to make changes. As they realize this their ability to write is compromised.

The fact that they are untethered as time travelers is both what gives them the power to rewrite and it is why they find it so difficult. Consider how Aaron gets stuck in a loop, repeating the same party sequence again and again, trying to get it right, but never really arriving anywhere.

Aaron: So how many times did it take Aaron…as he cycled through the same conversations…lip-synching trivia over and over? How many times would it take before he got it right? Three? Four? Twenty? I’ve decided to believe that only one more would have done it.

And this problem of a standard, the problem of a finding a foundation, is manifest in multiple ways. Not only are they losing their ability to make letters that conform to standard, they also lose the authority who was originally backing their efforts. Granger, Abe’s girlfriend’s father, was the money man who backed the construction of the time machine, but when Abe and Aaron set off to create a paradox on purpose he shows up and stops them. He has apparently become a time traveler, or will become one. He comes back and apparently stops them from doing whatever it is that would require them to tell Granger to go back to stop them.

Granger is a paradox, a self-referential object who is his own standard. Of course, as such, Granger immediately falls down. He sinks into a coma, into incomprehension, as soon as either of the time travelers get near him.

Abe: Basically, you have absolute impunity to do whatever you want…nobody can touch you. What do you do?

The trouble in Primer, the reason the time travelers can’t write, is because they’ve become their own standards. They’ve lost Granger, lost all limits, and as such they’re dissolving. The question for them is whether it’s possible, given their situation, to create their own limits, or whether they’re stuck in an endless loop, in a repetition, forever.
