Amanda Gefter’s “Finding Peter Putnam” is one of the most remarkable life stories I’ve ever read; here’s a snippet to give you an idea of who he was:
His name was Peter Putnam. He was a physicist who’d hung out with Albert Einstein, John Archibald Wheeler, and Niels Bohr […] “Only two or three times in my life have I met thinkers with insights so far reaching, a breadth of vision so great, and a mind so keen as Putnam’s,” Wheeler said in 1991. And Wheeler, who coined the terms “black hole” and “wormhole,” had worked alongside some of the greatest minds in science.
Robert Works Fuller, a physicist and former president of Oberlin College, who worked closely with Putnam in the 1960s, told me in 2012, “Putnam really should be regarded as one of the great philosophers of the 20th century. Yet he’s completely unknown.”
His ideas, insofar as I understood them, do sound remarkable and prescient. But I’m bringing it to LH for this tidbit:
Just then, a perfect opportunity arose to present Putnam to the public. Wheeler was invited by the Neurosciences Research Program at MIT to speak at their March 1975 meeting on “reality and consciousness.” He insisted he could only do it as half of a pair. […]
I listened to the meeting, recorded on a reel-to-reel, stowed away in the archives at MIT. Here, finally, was Putnam’s chance to explain his ideas to the top neuroscientists of the time. I pressed the headphones tight against my ears.
Wheeler had just finished speaking about the observer in quantum mechanics and introduced Putnam with a warning. “Some terms Peter uses, one needs a glossary to translate.” Wheeler placed a transparency on the projector—he’d made an actual glossary of Putnam’s terms. The crowd burst into laughter. I didn’t have to see Putnam’s face to feel it growing hot. When he began to speak, he stuttered.
“You only perceive signals that are useful for shaping behavior … A game is a special kind of mathematics … But for a game you need a goal function … We’re suggesting that the category repetition is a candidate … You’re searching for rules of choice that allow a repeating or self-reproducing path … There’s a transcendental core to the laws of physics themselves …”
The crowd grew restless. Wheeler’s talk had gone long, and there wasn’t time for Putnam to finish. The neuroscientists headed out for lunch and the tape cut out.
There are probably quite a few people who would benefit from such a glossary when they give talks. Thanks, Nick!
