How we’re meaningless now: Projections vs. simulations

Back when I was a lad, we experienced the absurdity of life by watching as ordinary things in the world shed their meanings the way the Nazi who opens the chest in Raiders of the Lost Ark loses his skin: it just melts away.

In this experience of meaninglessness, though, what’s revealed is not some other layer beneath the surface, but the fact that all meaning is just something we make up and project over things that are indifferent to whatever we care to drape over them.

If you don’t happen to have a holy ark handy, you can experience this meaninglessness writ small by saying the word “ketchup” over and over until it becomes not a word but a sound. The magazine “Forbes” also works well for this exercise. Or, if you are a Nobel Prize winning writer and surprisingly consistently wrong philosopher like Jean Paul Sartre, perhaps a chestnut tree will reveal itself to you as utterly alien and resistant to the meaning we keep trying to throw on to it.

That was meaninglessness in the 1950s and on. Today we still manage to find our everyday world meaningless, but now we don’t see ourselves projecting meanings outwards but instead imagine ourselves to be in a computer simulation. Why? Because we pretty consistently understand ourselves in terms of our dominant tech, and these days the video cards owned by gamers are close to photo realistic, virtual reality is creating vivid spatial illusions for us, and AI is demonstrating the capacity of computers to simulate the hidden logic of real domains.

So now the source of the illusory meaning that we had taken for granted reveals itself not to be us projecting the world out from our skull holes but to be super-programmers who have created our experience of the world without bothering to create an actual world.

That’s a big difference. Projecting meaning only makes sense when there’s a world to project onto. The experience of meaninglessness as simulation takes that world away.

The meaninglessness we experience assigns the absurdity not to the arbitrariness that has led us to see the world one way instead of another, but to an Other whom we cannot see, imagine, or guess at. We envision, perhaps, children outside of our time and space playing a video game (“Sims Cosmos”), or alien computer scientists running a test to see what happens using the rules they’ve specified this time. For a moment we perhaps marvel at how life-like are the images we see as we walk down a street or along a forest path, how completely the programmers have captured the feeling of a spring rain on our head and shoulders but cleverly wasted no cycles simulating any special feeling on the soles of our feet. The whole enterprise – life, the universe, and everything – is wiped out the way a computer screen goes blank when the power is turned off.

In the spirit of the age, the sense of meaninglessness that comes from the sense we’re in a simulation is not despair, for it makes no difference. Everything is different but nothing has changed. The tree still rustles. The spring rain still smells of new earth. It is the essence of the simulation that it is full of meaning. That’s what’s being simulated. It’s all mind without any matter, unlike the old revelation that the world is all matter without meaning. The new meaninglessness is absurd absurdity, not tragic absurdity. We speculate about The Simulation without it costing a thing. The new absurdity is a toy of thought, not a problem for life.

I am not pining for my years suffering from attacks of Old School Anxiety. It was depressing and paralyzing. Our new way of finding the world meaningless is playful and does not turn every joy to ashes. It has its own dangers: it can release one from any sense of responsibility – “Dude, sorry to have killed your cat, but it was just a simulation” – and it can sap some of the sense of genuineness out of one’s emotions. But not for long because, hey, it’s a heck of a realistic simulation.

But to be clear, I reject both attempts to undermine the meaningfulness of our experience. I was drawn to philosophical phenomenology precisely because it was a way to pay attention to the world and our experience, rather than finding ways to diminish them both.

Both types of meaninglessness, however, think they are opening our eyes to the hollowness of life, when in fact they are privileging a moment of deprivation as a revelation of truth, as if the uncertainty and situatedness of meaning is a sign that it is illusory rather than it being the ground of every truth and illusion itself.

Learning AI by doing: My new series of posts

The first in a series of six posts about my experiences learning how to train a machine learning system has just been posted here. There’s no code and no math in it. Instead it focuses on the tasks and choices involved in building one of these applications. How do you figure out what sort of data to provide? How do you get that data into the system? How can you tell when the system has been trained? What types of controls do the developers have over the outcomes? What sort of ways can I go wrong? (Given that the title of the series is “The Adventures of a TensorFlow.js n00b” the answer to that last question is: Every way.)

I was guided through this project by Yannick Assogba, a developer in the machine learning research group — People + AI Research –I’m embedded in at Google as a writer in residence. Yannick is natural born teacher, and is preternaturally patient.

The series is quite frank. I make every stupid mistake possible. And for your Schadenfreude, five more posts in this series are on their way…

In the form of a joke

I’m not sure why I bothered to write a joke that is in the form of a joke but is not funny. I am further bothered by the fact that I am posting it.

It was in response to a news item that a Ford dealership in Chatom, Alabama, was offering a free Bible, flag, and hunting rifle with each car purchased.

Here goes, and remember that this won’t actually be funny.

So, a Jew, a Canadian, and an eco-activist walk into a car dealership. The salesperson says, “We’re having a special sale. If you buy a car, you get three special gifts: A bible, a flag, and a rifle.”

The Jew asks “What type of bible?”

“King James,” says the salesperson.

“That’s not my type of bible,” the Jew says, and walks out.

The Canadian says, “I’m ok with the bible, but what type of flag?”

“American.”

“That’s not my type of flag,” the Canadian says, and walks out.

The eco-hippie pacifist seems not to notice and asks to be shown the most powerful, least eco-friendly car.

“Sure,” says the salesperson, slightly worried. “It’s this one. But don’t you want to know what type of rifle it is?”

“Is it high powered?” 

“It would take down a moose.”

“That’s all I need to know” says the eco-activist

“But aren’t you going to say that it’s not your  type  of rifle and leave?”

“Nope, it’s exactly my type of rifle.” says the eco-activist as she turns and puts a slug through the engine block of the car.   

“But that’s definitely not my type of car.”

YES THAT IS THE END OF THE “JOKE.”

In defense of public philosophy

Daily Nous has run a guest editorial by C. Thi Nguyen defending “public philosophy.” Yes! In fact, it’s telling that public philosophy even needs defense. And defense from whom?

Here’s a pull quote from the last paragraph:

To speak bluntly: the world is in crisis. It’s war, the soul of humanity is at stake, and the discipline that has been in isolation training for 2000 years for this very moment is too busy pointing out tiny errors in each other’s technique to actually join the fight.

And this is from near the beginning:

We need to fill the airwaves with the Good Stuff, in every form: op-eds, blog posts, YouTube videos, podcasts, long-form articles, lectures, forums, Tweets, and more. Good philosophy needs to be everywhere, accessible to every level, to anybody who might be interested. We need to flood the world with gateways of every shape and size.

So, yes, of course!

Who then is Dr. Nguyen arguing against? Who does not support increasing the presence of public philosophy?

Answer: The bulk of the article in fact outlines what we have to do in order to get the profession of philosophy to accept public philosopher as an activity worth recognizing, rewarding, and promoting.

If that op-ed is a manifesto (it is), sign me up!

[Disclosure: I am an ex-academic philosophy professor whose writings sometimes impinge on actual philosophy.]
