"Limits exist everywhere in nature. Physics, chemistry, biology, geology, astronomy—pick your field, dig into the literature, and you’ll soon be struck by how everything in the universe is defined by limits of temperature, weight, volume, density, number, power, frequency, speed, and more. Limits enable the functioning of systems at scales from the subatomic realm all the way up to galaxy clusters. If there is any physical thing that could credibly be claimed to be infinite, it is the universe itself. But not all cosmologists believe the universe is infinite, and proving whether it is or not may be impossible in principle. Leaving the totality of the cosmos to one side (an action possible only within the human brain—which does, most assuredly, have its own limits), everything else we encounter in life has boundaries. So, why have many people become obsessed with either denying or overcoming limits, to the point where they appear to feel that life can have meaning only if it’s tied to some limitless thing, quality, or substance? Humanity’s obsession with limitlessness probably began with the origin of language, which enables the asking of questions. People tens of thousands of years ago began to ask, “What happens to our essential sense of self when we die?” Their efforts to manage existential terror likely led them to tell stories about a boundless otherworld in which the dead live forever. Looking up at the night sky, they saw a realm of blackness punctuated by moving points of light; upon this screen they projected their wants, needs, and fears. Our lives and those of all the creatures around us may be brief, these early people must have thought, but there is another dimension that lies beyond—a dimension without endings. We’ve been searching for a path to infinity ever since."

"Agriculture enabled population growth and social complexity, but it gradually robbed soils of nutrients. Sailing ships guided with clocks and navigational charts could increase the scope of trade, but building wooden ships (and making charcoal for forging steel) was leading to the deforestation of whole continents. A reckoning with limits seemed to be in store. Then a miracle happened. People who lived in some key centers of global trade started using fossil fuels—energy sources capable of delivering power in previously unimaginable and seemingly endless quantities. Coal, oil, and natural gas enabled the development of transport technologies (steamships, railroads, cars, trucks, and airplanes) that overcame prior limits to the speed of travel and trade, so that products and resources that were abundant in one place could be transported to places where they were scarce. Fossil fuels could be used to increase the rates of resource extraction via powered mining machinery, and to process lower grades of ores as more concentrated ores were depleted. They could be fashioned into plastics and chemicals to substitute for some natural materials that were getting scarce, such as hardwoods and whale oil. And they could be made into artificial fertilizers, which could replace soil nutrients lost due to unsustainable agricultural practices. All these developments together enabled population growth at rates that far outstripped historic trends: human numbers expanded from one billion to eight billion in a mere two centuries. We were, in effect, stretching existing constraints on population and consumption to the point that it was difficult for many people to see that boundaries still existed at all."

"Intelligence is useful and entertaining. Companies go out of their way to hire applicants with high IQ scores, and spectacular intellectual achievements in the arts and sciences can win the hero-worship of generations ([like] Aristotle, Bach, Einstein). Measuring smarts is the job of an industry. Indeed, smartness is so endlessly praised in modern society that questioning its value may constitute one of the most dissident of human acts. High intelligence has been defined in many ways, but typically as the capacity for abstraction, logic, self-awareness, learning, planning, creativity, critical thinking, and problem-solving. High intelligence values itself, selects for itself, and fascinates itself. Our remarkable human intellectual achievements are deeply tied to language, whose development occurred as a self-reinforcing evolutionary feedback process. Hundreds of thousands of years ago, early humans derived a collective survival advantage by developing precursors of language, which enabled them to coordinate their behavior and to plan. But language requires extra brain power, so natural selection also worked to increase brain size, which enabled further development of language, which conferred still more survival advantages, and so on. If evolution produced high intelligence, then high intelligence is latent in evolution. Yet high intelligence is quite rare in nature. While all species communicate to some degree, only one has developed abstract, symbolic language. If language-based high intelligence offers survival advantages, why has it cropped up in nature only once?"

"We’ve spent the last few million years evolving big brains, and we won’t un-evolve them in short order. Further, encouraging dull-wittedness and ignorance would result in terrible short-term consequences (as we Americans are likely to discover during the second Trump presidency). Moreover, intelligence is cool: it gives us art, music, literature, science, mathematics, and so much more. At least some of these achievements and abilities are arguably worth saving. So, what’s our best long-term plan to avert self-destruction, given that intelligence is now baked into our species? There are those who say the solution lies in realizing that we fixate on just one kind of intelligence—linguistic, rational thinking—to the exclusion of others, and that we’d be better served by nurturing multiple intelligences, including musical, interpersonal, intrapersonal, spatial, bodily-kinesthetic, naturalist, and logical-mathematical. That’s good advice as far as it goes. But we’re unlikely to heed it sufficiently until we acknowledge why we came to rely so much on linguistic intelligence in the first place: it gave us power over our environment and over one another. So, our dilemma is as much one of ends (power) as means (language-based intelligence). In addition to needing a counterbalance to linguistic intelligence, we also need a way to check our individual and collective pursuit of excessive power."

"Most environmental dilemmas have to do with limits (usually limits to either resources or to waste sinks). And most environmental solutions have to do with reining in our wants and ambitions in some way. Cleverness may help at the margins—as when chemists identify a relatively harmless substance that can substitute for a toxic one. But without self-limits on population and consumption, no amount of cleverness can halt humanity’s accelerating march toward collapse. Economist William Stanley Jevons got an inkling of this stark reality in 1865, when he published his observation that making coal usage more efficient led to increased coal mining (and depletion), not conservation. Too often, we outsmart ourselves by thinking we’re doing something to save resources and reduce pollution, when in fact we’re just paving the way for more of the same. Another intelligence-resistant problem is deciding what’s a good life or a good death. These are arguably the most important personal questions with which any of us will ever grapple, but intelligence doesn’t always help with answers. It’s true that smart people sometimes avoid a lot of problems that plague less-smart people (such as falling prey to obvious scams and rip-offs). But they just as often end up burdening themselves and others around them with even bigger problems brought on by the unforeseen consequences of their own cleverness—as when a smart investor or inventor accumulates a huge fortune, over which their heirs fight bitterly, to the point that family dynamics are poisoned for generations to come. Finally, there is the uber-problem that should be at the top of all our minds—the long-term survival of humanity. We naturally want our species to stick around. And we like to think that our intelligence improves our prospects in that regard. But, so far, the evidence points in the opposite direction."
