AI is a process to convert solar energy to intelligence

  In 1739, Scottish philosopher David Hume delivered a strike to the Enlightenment ideal of human rationality. He famously declared that "reason is, and ought only to be the slave of the passions." To the thinkers of his era, this sounded cynical—even scandalous. But nearly three centuries later, modern cognitive psychology has proven Hume remarkably prescient. At the center of this proof lies confirmation bias : our deeply ingrained tendency to seek out, interpret, and recall information in ways that confirm what we already believe, while discounting or rationalizing away anything that contradicts it. When viewed together, Hume’s philosophy and cognitive science reveal a startling truth about human nature: reason rarely operates as an objective judge. Instead, it acts as a hired defense attorney taking orders from our emotional drives. The Emotional Master and the Intellectual Slave When Hume spoke of "passions," he meant our feelings, desires, instincts, and soci...

Long before theoretical physicists split the atom or neuroscientists mapped neural activity with fMRI, an 18th-century Scottish philosopher dismantled the metaphysical assumptions underpinning Western science. David Hume insisted on a radical principle: all human knowledge originates strictly in physical experience, and any concept that cannot be anchored to direct observation is a fiction of human invention. Across relativity theory, quantum physics, and modern cognitive neuroscience, 21st-century science repeatedly arrives at the exact empirical boundaries Hume mapped nearly three centuries ago. The Spark of Relativity: Hume’s Shadow over Einstein When Albert Einstein published his theory of special relativity in 1905, he credited an unlikely philosophical predecessor. During his early years as a patent clerk in Bern, reading Hume’s A Treatise of Human Nature shattered Einstein's uncritical faith in classical physics. Isaac Newton had built classical mechanics on the metaphysi...

  Wall Street measures success through linear return graphs and relative benchmark rankings. If a hedge fund manager leverages up, takes calculated risks, and outperforms the market, they are rewarded with massive performance fees and industry praise. If they blow up, they liquidate, reset, and launch a new fund next quarter. For the institution, wealth is a scoreboard. But for an individual, wealth is an existential buffer—and conflating the two is one of the most dangerous financial mistakes a person can make. At the heart of this divide lies the fundamental conflict between the math of expected returns and the math of human happiness . A hedge fund’s objective function is linear and absolute: maximize expected monetary returns max E[R] . Your personal objective function is psychological and concave: maximize expected lifetime utility max E[U(W)] . Because human well-being exhibits diminishing marginal utility, money works on a steep curve. The first million dollars buys security...

 There is an old, dark joke whispered among wilderness survivalists: When a bear charges a group of campers, you don’t need to outrun the bear—you only need to outrun the person next to you. It sounds cold, but for hundreds of thousands of years on the Pleistocene savannah, this was the supreme law of biological survival. In ancestral times, danger was everywhere. Nature etched a crucial heuristic deep into our neural code: It was never your absolute speed that determined whether you lived to see tomorrow; it was your relative speed. As long as you were not the slowest runner in the tribe, you were safe. That evolutionary programming kept our species alive. But today, it has become our psychological cage. 1. The Trap of the Relative Scale When we measure happiness using relative values—our income compared to our peers, our status compared to our neighbors, our achievements compared to social media highlights—we anchor our inner peace to a shifting horizon. In game theory and psycho...

 When George Mallory was asked why he wanted to climb Mount Everest, his response was three words: "Because it is there." It sounds glib, but it touches a deep paradox of human behavior. Why do we risk frostbite, high-G crashes, exotic diseases, and death to reach arbitrary summits or shave hundredths of a second off a lap time? Mount Everest summit ridge risk. 来源：Bryan Tropeano / Getty Images To make sense of voluntary suffering, we have to look through three lenses: biology, philosophy, and our search for meaning. The Evolutionary Roots: Why Risk Is Hardwired From a strict survival standpoint, extreme sports make zero sense. Evolution favors organisms that survive long enough to pass on their genes. Yet risk-taking persists in our DNA for vital evolutionary reasons: Exploration and Survival Premium: Early humans who dared to cross dangerous mountain passes or cross open ocean were the ones who found fresh water, fertile hunting grounds, and uncolonized territories. The dr...

  Human consciousness is burdened by evolutionary software written for a world that no longer exists. Deep in our neurology sits a relentless survival engine calibrated for an environment of tribal scarcity. It whispers three distinct anxieties: that we must accumulate without limit ( Greed ), that the clock is running out on every opportunity ( FOMO ), and that our peer's rise is our direct fall ( Envy ). Of these three, envy is the most tragic construct. Greed tastes like indulgence; FOMO feels like raw urgency; envy is pure, unadulterated suffering. Charlie Munger famously labeled envy the "dumbest" of all sins because it yields zero expected return—it offers no moment of pleasure, only the bitter friction of watching someone else succeed in a domain you value. It fixes our gaze not on what we need to thrive, but on what someone else possesses for status. The Grace of the Priority Collapse Yet, notice what happens when real misfortune strikes. When illness arrives, fin...
