Sentience is Physical, Part 2

Having recently moved to downtown Portland within spitting distance of Powell’s Books, I had to wander through the bookstore despite my preference for digital books these days. Digital books are easily transported, can be instantly purchased, and can be effortlessly carried in bulk. More, apps like Kindle Reader synchronize across platforms allowing me to read wherever and whenever I want without interruption. But is there a discovery feature to the shopping experience that is missing in the digital universe? I had to find out and hit the poetry and Western Philosophy sections at Powell’s as an experiment. And I did end up with new discoveries that I took home in physical form (I see it as rude to shop brick-and-mortar and then order via Amazon/Kindle), including a Borges poetry compilation and an unexpected little volume, The Body in the Mind, from 1987 by the then-head of University of Oregon’s philosophy department, Mark Johnson.

A physical book seemed apropos of the topic of the second book that focuses on the role of our physical bodies and experiences as central to the construction of meaning. Did our physical evolution and the associated requirements for survival also translate into a shaping of how our minds work? Psychologists and biologists would be surprised that there is any puzzlement over this likelihood, but Johnson is working against the backdrop of analytical philosophy that puts propositional structure as the backbone of linguistic productions and the reasoning that drives them. Mind is disconnected from body in this tradition, and subjects like metaphors are often considered “noncognitive,” which is the negation of something like “reasoned through propositional logic.”

But how do we convert these varied metaphorical concepts derived from physicality into something structured that we can reason about using effective procedures?… Read the rest

Running, Ancient Roman Science, Arizona Dive Bars, and Lightning Machine Learning

I just returned from running in Chiricahua National Monument, Sedona, Painted Desert, and Petrified Forest National Park, taking advantage of the late spring before the heat becomes too intense. Even so, though I got to Massai Point in Chiricahua through 90+ degree canyons and had around a liter of water left, I still had to slow down and walk out after running short of liquid nourishment two-thirds down. There is an eerie, uncertain nausea that hits when hydration runs low under high stress. Cliffs and steep ravines take on a wolfish quality. The mind works to control feet against stumbling and the lips get serrated edges of parched skin that bite off without relieving the dryness.

I would remember that days later as I prepped to overnight with a wilderness permit in Petrified Forest only to discover that my Osprey Exos pack frame had somehow been bent, likely due to excessive manhandling by airport checked baggage weeks earlier. I considered my options and drove eighty miles to Flagstaff to replace the pack, then back again.

I arrived in time to join Dr. Richard Carrier in an unexpected dive bar in Holbrook, Arizona as the sunlight turned to amber and a platoon of Navajo pool sharks descended on the place for billiards and beers. I had read that Dr. Carrier would be stopping there and it was convenient to my next excursion, so I picked up signed copies of his new book, The Scientist in the Early Roman Empire, as well as his classic, On the Historicity of Jesus, that remains part of the controversial samizdat of so-called “Jesus mythicism.”

If there is a distinguishing characteristic of OHJ it is the application of Bayesian Theory to the problems of historical method.… Read the rest
