‘The Brain with David Eagleman’

I’ve really been enjoying the PBS series “The Brain with David Eagleman” (here at Eagleman’s website, and here at PBS) over the last three episodes, and apparently there are a total of 6 episodes. What I’ve been seeing has prompted me to do more of my own thinking about reality, consciousness, etc.

I’m not sure how long the whole episodes will be available online, but here’s the link for the first one:

Past-tense, present-tense names

For the verb draw, my dictionary lists the past tense form as drew.

So then, people named Drew, like my neighbor’s son, have a past-tense name. I wonder if having a past-tense name influences how he experiences time — maybe he only senses things that have already happened. Well, I guess we all kinda do that. (For more, see here.)

Maybe if he’d been named Draw instead, he’d be experiencing the world in present-tense? Or if he had a name like Margot, which is presumably the present tense of Mar-went?

Nonfic: Unreliable narrators: When we talk, we say things

blog_snowconfusionWe make sounds that correspond to certain patterns we recognize as words and then we might be able to interpret from these words a meaning, and so we communicate. (Same goes for writing, only we go from visuals to meanings.)  But these meanings don’t necessarily have any connection to, well, anything, including reality. I find it useful (and I find usefulness a better standard for evaluating a statement than truth) to consider statements not as true or false, but simply the product of the statement-maker’s mind at the time the statement was made. As such, the statements characterize the statement-maker, but the statements themselves can be held by audience members without being evaluated; this way the audience member keeps an open mind and does not mistakenly privilege a statement as a “true” statement.

I’ve been thinking about this since Thursday when I was in a coffeeshop and two neighboring couples started making statements — assertions about and characterizations of and predictions for  reality. At the time I overheard (and recorded — there’s something wonderful about turning real life speech into symbols on paper) some of their statements, I understood these statements as political, in that they were discussing government policies, programs, and operations.

But today I’m thinking of their conversations as a philosophical one. These people were making assertions about reality (“The culture’s headed to where we want to take care of everybody…”). They were also characterizing — making metaphors and similes, drawing analogies, comparing — real things (“She’d dress like a street person” and “That’s what happened in Germany”), and they were also making predictions based on their assertions and characterizations (“They could shut the government down and you wouldn’t even know it”).

The content of their conversation may have been philosophical — metaphysical (pertaining to ultimate truth/reality), in particular — but the conduct of the conversation was not what I’d call philosophical, in that there was very little disagreement among them, and very few arguments were made to support assertions. Perhaps these people shared many premises and values so that they could deliver their assertions in brief. This also means, of course, that nobody was really learning much from each other; there was a “preaching to the choir” aspect there.

As a teacher, or as a philosopher, or as a busybody (or all three), I felt tempted to interrupt their discussion to challenge their assertions (as not being based on even so much evidence as poll results), their characterizations (which metaphors, analogies, and comparisons are not really statements that can be judged true or false, since these things are, by definition, not literally true. However, the comparisons seemed to be supporting their assertions by means of negative connotation.), and their predictions (as being pure bullsh!t, since, as Wendell Berry pointed out in “The Unsettling of America”, the future does not exist).

I did not jump in, which interruption likely would not have been welcomed and which would have likely upset the calm of the social situation. Everyone is entitled to one’s own beliefs, of course. But if we are not at least willing to entertain some philosophical skepticism about our own beliefs and assertions about reality, we risk becoming “unreliable narrators” of our own lives, people whose statements are always asterisked, in the sense of: “Well, Matt* complained about the party — (*but you know how he tends to be).”

I don’t want my statements to be predictable, and I don’t want my statements to be qualified with an asterisk. (I originally used the plural “we” in that sentence, but I ought to speak only for myself. How can I possibly speak authentically for others?) Yet, a way to avoiding being predictably biased seems to be to consider all statements I hear and read, as well as all statements I make, to be already-asterisked (with a different asterisk, one that indicates the statement is merely a statement, truth value unknown), and to not judge any statement as true or false too quickly.

Post Script: This post was partly inspired by A.M.B.’s post about reality in fiction. While I agree that statements in fiction works ought not to be taken as true, I’d also suggest that this skepticism be applied to nonfiction works, too. While a writer shouldn’t knowingly lie in any work labeled “nonfiction,” the writer’s statements aren’t really true, either. After all, we construct the stories we tell, whether they’re fiction or nonfiction; it’s not like we can go around picking stories we find lying around. Nonfiction assertions about “what really happened” are the products of a mind describing experience, which experience doesn’t really happen in words, anyway. Just as storytellers tend to naturally, unconsciously, compress time in their narratives and relate the events in sequence, so do storytellers label particular sensory experiences (like hearing a particular sound) with generally known terms (“a bell tolled”). Research suggests this storytelling may happen even at the subconscious level, as our brains coordinate sensory inputs in ways that make the world knowable to us.

So, it may be unsettling to live in a world of (mild) skepticism toward assertions about reality, but it can perhaps keep us from falling into believing wrong ideas, having a limited concept of reality. This skepticism reminds me of the epistemologically beautiful thing about science: any scientific idea must be liable to be revised or replaced — or else science isn’t science!
