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.
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.
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."
One of my earliest cognitive therapy patients asked if we'd spend time exploring his past. He thought we might find patterns that would explain his depression. I was taken aback. I had just discovered a set of powerful, active techniques that helped people change how they felt in the here-and-now. As a psychiatric resident, I had seen that endless venting without specific techniques for change led to little or no relief.
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.
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.
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.
You know that ache you get when you stumble across evidence of your past self being genuinely, effortlessly happy? It's not that you want to go back. Not really. I think what kills you is the proof staring back at you - proof that you were once capable of feeling that alive, that connected, that certain about where you belonged in the world.
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.
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.
