Putting the “cog” in “cognitive”: on the “mind as machine” metaphor
by Yohan J. John Scientists have long acknowledged the power of metaphor and analogy. Properly understood, analogical and metaphorical thinking are not merely ornamental aspects of language, but serve as a bridge from the known to the unknown. Perhaps the most important example of this process was the one that epitomizes the scientific revolution: Isaac…
Ways of Knowing
by Yohan J. John Once, some years ago, I was attending a talk by the philosopher Slavoj Žižek at the Brattle Theatre in Cambridge, Massachusetts. He was engaged in his usual counterintuitive mix of lefty politics and pop culture references, and I found myself nodding vigorously. But at one point I asked myself: do I…
Why some neuroscientists call consciousness “the c-word”
by Yohan J. John As a neuroscientist, I am frequently asked about consciousness. In academic discourse, the celebrated problem of consciousness is often divided into two parts: the "Easy Problem" involves identifying the processes in the brain that correlate with particular conscious experiences. The "Hard Problem" involves murkier questions: what are conscious experiences, and why…
Will next year feature a Summer of Love or a Summer of Hate?
by Yohan J. John Ever since Donald Trump's shocking victory in the recent US Presidential Elections, I have gotten a kick out of reminding people of the following: next year we will mark 50 years since the Summer of Love. One response, which I imagine reflects a common sentiment among left-liberals, was a sardonic laugh…
Installing the Idol: On the real power of imaginary notions
On Pokémon GO and Psychogeography (and Philip K. Dick)
by Yohan J. John There's no real downside to engaging with pop culture. If you happen to get into the latest craze, you can participate in collective joy. If it doesn't quite move you, you can join in with the 'haters' and engage in a different but no less enjoyable communal experience. Either way, you…
Decision-making: the fine art of throwing away information
by Yohan J. John Human decision-making routinely confounds our attempts at understanding. Right now, the western world is in a state of bafflement and anxiety brought on by unprecedented collective decisions. From the British public's vote to leave the European Union to Republican voters' selection of Donald Trump as their presidential candidate, the past month…
Persons all the way down: On viewing the scientific conception of the self from the inside out
by Yohan J. John Ridiculing the intellectual backwardness of our forebears is a popular pastime. How silly our ancestors were! They thought the earth was flat! They believed in dragons and fairies! And even when they started to emerge from humanity's childhood, they came up with ideas like phlogiston! And luminiferous aether! Among neuroscientists, one…
The “Streetlight Effect”: A Metaphor for Knowledge and Ignorance
I Know That Feel, Bro: What Aziz Ansari and Celine Dion taught me about ‘relating’
Some free-form musings on the Star Wars phenomenon
What do we mean by “Nature”? And what do we mean by “Human Nature”?
Me and My Brain: What the “Double-Subject Fallacy” reveals about contemporary conceptions of the Self
by Yohan J. John What is a person? Does each of us have some fundamental essence? Is it the body? Is it the mind? Is it something else entirely? Versions of this question seem always to have animated human thought. In the aftermath of the scientific revolution, it seems as if one category of answer…
Be Careful What You Wish For: Some Wild Speculation on Goodhart’s Law and its Manifestations in the Brain
by Yohan J. John This is the era of metrics: it seems that if we are to hack a path through the information jungle of the 21st century, we must be armed with an arsenal of scores, quantities, indices, factors, grades, and ratings. Our corporate and governmental overlords seem most comfortable parlaying in the seemingly…
The Varieties of Probabilistic Experience
by Yohan J. John Probability theory is a relative newcomer in the history of ideas. It was only in the 19th century, two centuries after Isaac Newton ushered in the scientific revolution, that thinkers began to systematize the laws of chance. In just a few generations, the language of probability has seeped into popular discourse…
How informative is the concept of biological information?
by Yohan J. John We are routinely told that we live in a brave new Information Age. Every aspect of human life — commerce, entertainment, education, and perhaps even the shape of consciousness itself — seems to be undergoing an information-driven revolution. The tools for storing and sharing information are becoming faster, more ubiquitous, and…
If the DNA molecule is the book of life, it’s a very strange book indeed
by Yohan J. John The DNA molecule is often described as the book of life, as a blueprint for constructing the organism, or as a program for computing the organism. These metaphors have become so pervasive that we often forget that they are metaphors. In this essay I'd like to take this class of metaphor…
Information: the Measure of All Things? Part II: The Genius in the Gene
by Yohan J. John In Part I of this series, we looked at how the concept of information brought communication and computation together. Claude Shannon and the other pioneers of information theory showed that discrete symbols could be used to encode and transmit almost any sort of message, and that binary digits were the simplest…
Information: the Measure of All Things? Part I: Communication, Code and Computation
by Yohan J. John Metaphor is a hallmark of human communication, and a vital tool of scientific thinking. Along with its more formal cousin, analogy, metaphor allows us to create linguistic and conceptual bridges from the known to the unknown. Some of the greatest breakthroughs in science began with an analogical leap between seemingly unrelated…
