...Predictive processing argues that perception, action and cognition are the outcome of computations in the brain involving both bottom-up and top-down processing – in which prior knowledge about the world and our own cognitive and emotional state influence perception.
In a nutshell, the brain builds models of the environment and the body, which it uses to make hypotheses about the source of sensations. The hypothesis that is deemed most likely becomes a perception of external reality. Of course, the prediction could be accurate or awry, and it is the brain’s job to correct for any errors – after making a mistake it can modify its models to account better for similar situations in the future.
But some models cannot be changed willy-nilly, for example, those of our internal organs. Our body needs to remain in a narrow temperature range around 37°C, so predictive processing achieves such control by predicting that, say, the sensations on our skin should be in line with normal body temperature. When the sensations deviate, the brain doesn’t change its internal model, but rather forces us to move towards warmth or cold, so that the predictions fall in line with the required physiological state.
"The truth knocks on the door and you say, ‘Go away, I’m looking for the truth,’ and so it goes away. Puzzling." -- Robert M. Pirsig
I was saddened to learn that Zen and the Art of Motorcycle Maintenance author Robert M. Pirsig died today at the age of 88.
I read the pop philosophy treatise Zen and the Art of Motorcycle Maintenance in college and thought it was the greatest book ever. I read it again 15 years later and didn't get as much out of it the second time around. It's been another 15 years since I re-read it and I no longer remember why I had those opinions (I have a lousy memory when it comes to books and movies). I think I should give it another try and see what my current nervous system thinks of his exploration into the nature of quality.
One thing is for certain, the title of the book is one of the best ever (and has been imitated ever since the book came out in 1974), and the paperback cover design is absolutely iconic. [UPDATE: reader Simenzo corrected me. Zen in the Art of Archery, by Eugen Herrigel, was published in 1948]

Zen was published in 1974, after being rejected by 121 publishing houses. "The book is brilliant beyond belief," wrote Morrow editor James Landis before publication.
Pippin Barr's Snakisms is a version of the classic game Snake, but with a selection of philosophical viewpoints to choose from at the outset.
SNAKISMS was begun on the strength of the idea of "Ascetic Snake", a game of Snake in which the snake isn't meant to eat the apple (or whatever that thing is in Snake). That basic reversal of the standard form of the game struck me as funny because those sorts of things always strike me as funny, but on turning to actually make the game it seemed pretty clear it was too much of a throw-away idea all on its own.
And so it came to pass that I decided I needed to make a whole set of Snake games based (loosely) on different philosophies, eventually settling on the idea of "isms" because SNAKISMS is really a pretty great title for a game, I think you'll agree. The design process took a surprisingly long time in terms of coming up with a set of "reasonable" interpretations of philosophies/isms that could be translated in some way to the mechanics of the original Snake game.
Artist Pippin Barr wrote his PhD video game values and got a Masters in UI metaphors, so it's natural that he's created Snakisms, a collection of 22 variants on the classic video game Snake (best remembered from the era of candy-bar featurephones), each of which is meant to illustrate (or at least make a joke about) philosophies from Stoicism (your snake runs into things, pauses a moment, shakes it off and presses on) to Determinism (your snake drives itself), to Holism (just try it). They're lovely, witty fun! (via Kottke) Read the rest
Ayelet Waldman is a novelist, non fiction author, and former federal public defender. Her latest book is called A Really Good Day: How Microdosing Made a Mega Difference in My Mood, My Marriage, and My Life. I interviewed her this morning.
Why did you start microdosing?
I started microdosing because I was profoundly and dangerously depressed. I have a mood disorder and for many, many years my medication worked great. I took it, I did what my doctor told me and everything was fine. But at some point my medication stopped working. I tried all sorts of different things. And nothing helped. I was getting worse and worse and more and more full of despair and more and more full of rage and more and more unstable and I became suicidal. I started doing things like googling the effects of maternal suicide on children and I was so terrified that I was going to do something to myself, that I was going to hurt myself, that I decided to do something drastic and something that some people might think is crazy -- I decided to try microdosing with L.S.D.
Did it work?
Oh absolutely. It worked for sure. It's sub-perceptual. In fact, if I told you right now, "Hey Mark, I slipped a microdose of LSD. in your coffee," you wouldn't even know the difference. The effect for me was instantaneous. My depression lifted right away. The book is called A Really Good Day because at the end of that very first day, I looked back and I thought, "that was a really good day." It wasn't like everything was perfect. Read the rest
A trio of scholars who study the psychology and philosophy of science have written a fantastic paper for Springer's Sythese looking at the way that climate change conspiracy theorists construct their view of the world, and how these conspiracy theories contain self-contradictory theses (like the idea that climate change can't be predicted and the idea that the data shows we're actually headed for an ice-age).

Released today, a new explainer video by In a Nutshell that asks the question "What are you?" How much of your body can you remove (and replace with cyborg parts) before you stop being you? If you donate an organ, do you become part of the organ recipient? And what makes your cells "you?" Read the rest
Rogue archivist Carl Malamud writes, "From May 11, 1947 until January 29, 1948, Gandhi gave a speech after prayer meetings 129 times. It was a narrative of his life and of the times. All India Radio broadcast his talks to the nation, and everybody stopped to hear what the Mahatma had to say. On January 30, Gandhiji didn't make it to the microphone. " Read the rest
Rick Kleffel sends us his latest podcast (MP3), "A conversation with one of the authors of a wonderful and strange book; science-fiction thought experiments ('robot versus baby') informed by social psychology experiments of fascinating design, part ethics, philosophy, neuroscience, the minds of god and the dead and machines... authentically mind-boggling. And Fun!" Read the rest
Philosopher John Danaher's new paper "Will life be worth living in a world without work? Technological Unemployment and the Meaning of Life" assumes that after the robots take all our jobs, and after the economic justice of figuring out how to share the productivity games can be equitably shared among the robot-owning investor class and the robot-displaced 99%, there will still be a burning question: what will give our life meaning?
