Attention is the brain's filtering mechanism; what passes through that filter is what gets encoded. What gets encoded becomes memory. And memory is the raw material of identity. So in the architecture of your identity, attention is the doorway.
Plato's choice of this word is deliberate. He is not describing neutral carriers. He is describing people whose job is manufacturing a convincing reality for an audience that cannot see behind the curtain. Here is what matters clinically: the conjurers are not necessarily villains. They may be devoted parents, conscientious teachers, or well-meaning community leaders.
A few years ago, I climbed over a gate and found myself gazing down at a valley. After I'd been walking for a few minutes, looking at the fields and the sky, there was a shift in my perception. Everything around me became intensely real. The fields and the bushes and trees and the clouds seemed more vivid, more intricate and beautiful.
Your consciousness can connect you with the entire universe, a groundbreaking study suggests. Experts from Wellesley College in Massachusetts claim that traditional connections in the brain cannot fully explain how we are aware of our existence. Instead, they argue that quantum physics taking place within our skull is what generates awareness. This includes the idea that particles can exist in multiple states and locations at the same time.
The simple feeling of being is the fundamental basis of every momentary perception. What's happening right now is the only starting point there could ever be. The simple feeling of being is without border or boundary. The simple feeling of being is inescapable. It is not something that needs to be created or generated or sustained or practiced. It is what is here already.
Metaphors are linked to how we experience the world around us, according to seminal work by researchers George Lakoff and Mark Johnson. In English, we "move forward" with our lives and don't "retreat into" the past. We speak about people who are "cold as ice" and "heavy" matters we need to resolve. Some of these metaphorical expressions are more than just, well, expressions-they are actually based on our sensory experiences. This mind-body link is called "embodied cognition."
In my previous post, I summarized my response to Christian de Weerd, who denied that a Darwinian approach to consciousness is even possible. I argued that consciousness science has unnecessarily insulated itself from the evolutionary tools that revolutionized our understanding of every other biological phenomenon, and that treating human consciousness as the paradigm case distorts our picture of consciousness as a natural phenomenon spanning millions of species across millions of years.
Recent integrative approaches suggest that physics cannot be adequately characterized by magnitude-based distinctions alone, such as those implied by Big-P, little-p, and mini-p physics. While these categories capture differences in scope and historical impact, they fail to address the heterogeneity of physical activity itself. To remedy this, I propose the Five Fs of physics: force, friction, flux, formulation, and foundational structure.
For Plato, psyche meant something like what we'd now call mind -understood as a complex system requiring governance. The psyche had distinct parts: a reasoning part that deliberates, a spirited part that feels emotion and courage, and an appetitive part that desires. Each part has its own function and its own form of excellence. And crucially, these parts need to be governed-integrated under what Plato called constitutional self-rule.
Many philosophers strike me as like Polish apparatchiks in 1983-they turn up to work and do what they did yesterday just because they don't know what else to do, not because they seriously believe in the system they are maintaining. I think it's not been fully appreciated how much of a blow it is to the confidence of the field's youth that scientific ambitions are increasingly abandoned as untenable.
This story is about complexity, advanced math, cognition, and machine computation. But hold on. For this exercise, my task is to take this complex idea and reduce it-to simplify it into something less daunting and (I hope) a bit easier to understand. So, let's take a step back. My bet is that most of us learned our first piece of geometry with two letters: x and y.
A drawn circle is at least something physical. You can see it, touch it, erase it. The skeptic can still say, "Circles are grounded in physical reality. Justice is different; it's just an idea in your head." So let's talk about the number two. Point to it. Not two apples, not two fingers, not a numeral on a page-that's just a symbol.
For most of my life, I thought of myself as a fixed entity: This is me. These are my traits. This is who I am. I assumed I was essentially that same person who loved sugary cereal at age 8, fried chicken at 12, and tequila at 21, and who still loves those things now, even if my stomach disagrees. But this is an illusion. Neuroscience, physics, and Buddhism all agree: There is nothing fixed about us-not even close.
It is easy to be good in a good world. What is difficult is to be good in an evil world, where the egoism of others and the egoism built into the institutions of society attack us and threaten to annihilate us. Under such conditions, the only possible reaction would seem to be to oppose evil with evil, egoism with egoism, hate with hate; in short, to annihilate the aggressor with his own weapons.
The fastest human in the world, according to the Ancient Greek legend, was the heroine Atalanta. Although she was a famous huntress who joined Jason and the Argonauts in the search for the golden fleece, she was most renowned for the one avenue in which she surpassed all other humans: her speed. While many boasted of how swift or fleet-footed they were, Atalanta outdid them all. No one possessed the capabilities to defeat her in a fair footrace.
The word umwelt comes from biology, coined by ethologists studying animals in their natural habitats. It refers to the world as an organism can perceive it, based entirely on its sensory equipment. A bat's umwelt is built from echo. A dog's from scent. A tick's world is dominated by a single chemical cue that tells it when to drop from a branch onto a passing mammal.
