Causality, the memorable aspect of Plot, is a narrative device.
Causation, on the other hand, is a more dubious proposition.
The philosopher David Hume observed that perceiving cause & effect would enhance memorability, but ultimately refused to stipulate whether human beings were capable of absolutely delineating any actual cause. In other words, we might basically say, Causation is a matter of Physics and Causality is an aspect of Literature. That's okay for starters. But then, at the intersection of Science and Literature we find History.
In general, historians are well practiced at treating causation with a hefty dollop of dubiousness. We trust that causation exists, and deserves its proper due as we attempt to account for the past, but in narrating the causalities which might explain some historical transition, historians discuss context, conditions, and multiple causes. Like high school graduates who begin college Physics, we've learned that we *do* have to account for friction and wind resistance in reconstructing reasonable scenarios. Occam's razor is frequently found to be moot. When historians dig hard enough, we find causes multiplying, but not unnecessarily.
In short, historians deal with complexity. We make attempts to generalize, relativize and prioritize multiple causes. In the non-fiction narratives of professional historians, the plot is rarely oversimplified. Most historians do not reduce complex causes to categorical dependence on one factor. Cleopatra's beauty might have been one reason she wooed and won over Julius Caesar and Marc Antony, but it was not the only reason. A pretty face might have been one "necessary" cause for her bedding of two autocrats. It was not a "sufficient" enough cause to explain those relationships.
Historians are usually careful to build narratives that feature complex causality.
But Memory (collective, social, and personal) more often does quite the opposite.
In the popular memory of Abraham Lincoln, he single-handedly freed the American slaves. In some social group's memories of Ronald Reagan, he gets the almost full credit for ending the cold war. And so on. Elvis Presley started Rock and Roll. John F. Kennedy was elected because of TV. Yoko Ono broke up the Beatles. Mary Magdalene was a prostitute who married Jesus, or at least wanted to. True or false, these narratives all predominate in a significant bulk of the popular memory. What they all have in common is a simplified causality.
As I suspect you'll agree, this dynamic of imagining causation goes far beyond stories of literature.
It's been plausibly suggested that the largest religion of the world is actually superstition. If I do the right things in life, I'll get better parking spots at the grocery. If I yell at my sister, I might go to hell. Causality. Plot. Karma. Pennance. My sports team usually wins if I stay home and watch on TV. Mom got cancer so God could bring us closer together. We go through life looking for reasons and inventing those reasons more often than not. The most terrifying thing about Kafka's stories, observed E. H. Carr, was their complete lack of discernible causes. Nothing you do guarantees good fortune and bad people are not always punished. That's horrifying and disturbing. People prefer to think differently.
Aside from subconscious preference, however, I believe there are practical dynamics that encourage these types of perceptions to reach beyond short-term memory and become anchors of memorable stories.
The primary contentions of this series so far are (1) that memory requires efficiency, (2) that story is a phenomenon which reduces experience efficiently, and (3) that causality in particular is an excellent tool for maximizing efficient remembering.
What are some ways that causality focuses memory?
One of the most common historical fallacies is "post hoc, ergo propter hoc", but why is it so common? Hasn't it been beaten into us well enough? Why do so many of us still need to keep being reminded that B following A doesn't prove A caused B? The ubiquity of this fallacy, itself, requires some explanation.
Likewise, the "Great Man" theory of history is an overwhelmingly popular method of oversimplifying causality. It's a common mistake because it's a common perception. Not that it's strictly proper to describe any of this as a 'perception'.(*) At any rate, these are two common ways, that are causally based, by which people tend to mis-remember the past.
By the way... What if, instead of superstition and inflated causality being merely typical features of popular story-construction... What if it's somehow causality that's driving these memory processes? That is, instead of the human tendency to need "reasons for things" being a prima facie instinct from birth... What if our fixation on causality is something that became psychologically dominant only after our mnemonic needs allowed Plot do predominate our storied understanding of the world?(*)
(*)Note my "only after" makes this "necessary". I'm not claiming it to be sufficient. Causes usually are complex. At any rate, this sidebar is somewhat ancillary to my interests, so I've bumped some deeper thoughts about it to the bottom. See below.(*)
Let's not spend too much time asking why we ask why. That's one too many chicken/egg questions. Causality may have had a strong hand in developing Story - that is, the experience of cause and effect may be one reason we learned how to build stories(*) - but that's beyond my scope at the moment. The one thing I'm confident about is that causality is a primary factor in making stories more memorable.
That key idea is where I'm going to keep building this camp.
There's too much in the past, to remember it all. A story is a method for remembering efficiently. Causality is the most efficient kind of rememberable storying. We can observe patterns in the way causality serves as the focus of memories.
So far, so good?
In my next post, I plan to focus on more specific examples of how Memory tends to inflate "necessary causation" into "sufficient causality".
