We're all hydrogen atoms that learned how to talk.

They became upright and taught themselves the use of tools, domesticated other animals, plants and fire, and devised language. The ash of stellar alchemy was now emerging into consciousness. At an ever-accelerating pace, it invented writing, cities, art and science, and sent spaceships to the planets and the stars. These are some of the things that hydrogen atoms do, given fifteen billion years of cosmic evolution. Carl Sagan

Therapy speak is making us miserable

I had a client who described a lot of their problems in therapy language. I told them something like: “hey, I believe that psychotherapy was really useful for you at the time—but consider the possibility that the pathologizing language you picked up from that culture is distancing you from your experience and causing you to consider normal things problematic.” They stopped using therapy framing and found that their inner life…

Attention is first philosophy

source · ideas.imbue.com ↗

1\. Attention is the practice beneath all philosophical practices. Nearly every contemplative tradition—Stoic, Platonic, Christian monastic—was built on attention as the foundational practice. Practices like fasting, physical training, and meditation exist to guard the stillness attention requires. Philosophy, in this sense, is a discipline of perception, not mere argumentation. 2\. Distraction is a perennial human problem,…

A considered life

source · themicrophilosopher.com ↗

The lesson to take from Nietzsche is that we all may not fully understand the implications of our most cherished values, our personal beliefs, or actions, and live our entire lives in ignorance or self-denial, unconsciously undermining ourselves and others. How do we avoid this? We need to make sure that the belief systems we occupy, and the values we deeply attach ourselves to, are actually serving us and those around us. We…

A short intro to Baruch Spinoza's philosophy

Baruch Spinoza: The Philosopher Who Saw God in Everything Baruch Spinoza stands as one of the most radical and influential philosophers in Western history, yet his ideas remain surprisingly relevant to modern concerns about meaning, freedom, and our place in the universe. Born in 1632 in Amsterdam to Portuguese Jewish refugees, Spinoza would eventually be excommunicated from his community for heretical views—only to produce a…

Dare to feel

Cummings should know — just four years earlier, he had fought that hardest battle himself: When he was awarded the prestigious Academy of American Poets annual fellowship — the MacArthur of poetry — Cummings had to withstand harsh criticism from traditionalists who besieged him with hate for the bravery of breaking with tradition and being nobody-but-himself in his art. With an eye to that unassailable creative integrity…

We're all unique protons and electrons

Most human beings are elementally similar but structurally different. Every living being around us is elementally similar, most are roughly the same few elements, but the arrangements of those carbons, protons, neutrons, electrons are different. That arrangement is what makes you you. That is the unique pattern for every species on Earth, and even for every individual. Seven billion humans, billions of animals, other species,…

I’m not trying to push you in any direction, honest. If you get everything totally wrong, too bad, but you’ll still be remembered forever for trying. Even Pontius Pilate has immortality of a sort. Both Eliezer Yudkowsky and Beff Jezos have their page in the textbooks assured. If you’re a well-off Silicon Valley person, you’re already well-placed to join them. So participate in the discourse.

Gitanjali 48

source · poets.org ↗
[Pure and sublime poetic beauty](https://poets.org/poem/gitanjali-48).The morning sea of silence broke into ripples of bird songs; and the flowers were all merry by the roadside; and the wealth of gold was scattered through the rift of the clouds while we busily went on our way and paid no heed.We sang no glad songs nor played; we went not to the village for barter; we spoke not a word nor smiled; we lingered not on the way. We quickened our pace more and more as the time sped by.The sun rose to the mid sky and doves cooed in the shade. Withered leaves danced and whirled in the hot air of noon. The shepherd boy drowsed and dreamed in the shadow of the banyan tree, and I laid myself down by the water and stretched my tired limbs on the grass.My companions laughed at me in scorn; they held their heads high and hurried on; they never looked back nor rested; they vanished in the distant blue haze. They crossed many meadows and hills, and passed through strange, far-away countries. All honour to you, heroic host of the interminable path! Mockery and reproach pricked me to rise, but found no response in me. I gave myself up for lost in the depth of a glad humiliation—in the shadow of a dim delight.The repose of the sun-embroidered green gloom slowly spread over my heart. I forgot for what I had travelled, and I surrendered my mind without struggle to the maze of shadows and songs.

On the joys of writing

What I didn’t realize was that writing a Substack would also reignite my intellect. Over the first five months, I posted an essay nearly every week. I’ve always read a lot, but before, the words passed through me—my mind a sieve. Now, I keep dozens of running files in my notes app about topics I hope to write about. Before, spare moments were taken up by mindless scrolling. Now, they’re spent writing and editing. Substack…

We are a collection of particles but...

From a physicist’s perspective, no complex system is weirder or more challenging than life. For one thing, the organization of living matter defies physicists’ usual expectations about the universe. Your body is made of matter, just like everything else. But the atoms you’re built from today won’t be the atoms you’re built from in a year. That means you and every other living thing aren’t an inert object, like a rock, but a…

My little heart

So much held in a heart in a lifetime. So much held in a heart in a day, an hour, a moment. We are utterly open with no one in the end—not mother and father, not wife or husband, not lover, not child, not friend. We open windows to each but we live alone in the house of the heart. Perhaps we must. Perhaps we could not bear to be so naked, for fear of a constantly harrowed heart. When young we think there will come one person…

Virtue cannot be known without knowing vice

"I cannot praise a fugitive and cloistered virtue, unexercised and unbreathed, that never sallies out and sees her adversary but slinks out of the race, where that immortal garland is to be run for, not without dust and heat. Assuredly we bring not innocence into the world, we bring impurity much rather; that which purifies us is trial, and trial is by what is contrary. That virtue therefore which is but a youngling in the…

We are borrowed stardust

I thought of Einstein, who at sixteen, lonely and introverted, began wondering about the nature of the universe by imagining himself chasing a beam of light through outer space; I thought of the poet Rainer Maria Rilke, also lonely and also dedicated to the light, who at the same time was formulating his general theory of love as “two solitudes that protect, border, and greet each other.” And I thought about how love is…

Philosophy understood as a way of life

Hadot isn’t saying philosophy-as-life disappeared after antiquity and medieval times, leaving only professors in universities. He notes that the existentialists, for instance, carried this tradition forward. Other scholars—like Matthew Sharpe and Michael Ure—have shown that it runs through Socrates, the Stoics, medieval and early modern thinkers, Descartes, Bacon, Schopenhauer, Nietzsche, and even Foucault. My own…

Stephen Hawking on the philosophy of life

Guest: You have said you do not believein God. Do you have a philosophy of life that helps you? Stephen Hawking: It is clear that we are just an advanced breed of primates on a minor planet orbiting around a very average star, in the outer suburb of one among a hundred billion galaxies. BUT, ever since the dawn of civilization people have craved for an understanding of the underlying order of the world. There ought to be…
