culture shapes values, and those values shape history.
it attempts to interpret historical phenomena such as the rise of agriculture, the Scientific Revolution, and our current world system from a cognitive perspective. In doing so, it recognizes the enormous complexity of human culture and draws from recent advances in systems thinking to develop an interpretative framework.
Each culture, they argued, develops its own version of reality that arises from its specific physical and environmental context. If you try to “essentialize” a culture's frame of reality and compare it with that of another culture, you risk decontextualizing it and therefore invalidating its unique attributes.
the broad east-west axis of Eurasia meant that newly domesticated crops could easily spread across zones with similar climates, whereas the north-south axis of the Americas prevented it. Similarly, new infectious diseases that arose in humans from animal domestication spread in waves across Eurasia, leaving survivors with immunity. All this led to the Eurasian population developing the tools of civilization before the rest of the world, resulting in the guns, germs, and steel that permitted them to dominate other continents.
It's assumed there are no intrinsic behavioral differences between the people of various parts of the world, and, therefore, we need to look to environmental factors to explain how each developed in different ways.
Wow.people behave similarly so it must be environmental.not racial.however it creates its own cultual imperialism
This book takes an entirely different approach from historical reductionism. Instead, it offers a cognitive approach to history, arguing that the cognitive frames through which different cultures perceive reality have had a profound effect on their historical direction.
the book shares much with the postmodern critique of Western civilization, recognizing those capitalized universal abstractions such as Reason, Progress, and Truth to be culture-specific constructions. In fact, a significant portion of the book is devoted to tracing how these patterns of thought first arose and then infused themselves so deeply into the Western mind-set as to become virtually invisible to those who use them.
the relationship between cognition and history is not one-way but reciprocal. The cognitive patterns of humans living their day-to-day existence are continually affected by what goes on around them, and the consequent actions they take are continually affecting whatever is around them.
a two-way flow going on, which they call “niche construction.” As organisms adapt to their environment, they are not just finding their niche but actively constructing it, and, by doing so, they are shaping the environment for themselves, their offspring, and the other organisms around them.
A recent study, for example, has found that Chinese provinces that rely on rice, which requires a great deal of mutual cooperation within the community, have a more holistic outlook than those provinces that rely on wheat, where farmers can manage more easily by themselves.

A complex system, on the other hand, arises from a large number of nonlinear relationships between its components with feedback loops that can never be precisely described. Any living thing, or system comprising living things, is complex: a bacterium, a brain, an ecosystem, a financial market, a language, or a social system.
One important attribute of a complex system is a special type of reciprocal causality: each part of the system has an effect on the whole, while the system as a whole affects each part. Because of this, a complex system can never be fully understood by reducing it to its component parts.
at a certain point, the cohesive set of reciprocal causal relationships that form the system can rapidly become unraveled, and when that happens, the system undergoes what's known as a critical transition, leading to a new stable state that can be either more or less complex than the previous one. When this happens, it's very difficult for the system to shift back to the state it was in previously, a characteristic known as hysteresis.
In recent decades, cognitive scientists have made important discoveries into how we learn, as infants, to make sense of the reality around us. They've shown that our worldview is based on root metaphors we use to frame other aspects of meaning without even realizing we're doing so. These core metaphors, which arise from our embodied existence, structure how we conceptualize our world.
One important way it does this is to detect patterns in what it receives: What's new? What's recurrent? What's important? What correlates with something else? Out of these patterns, as infants, we begin to make sense of our surroundings: recognizing family members, picking up on speech formations, and gradually learning to become members of our community. As we grow older, we continue to rely on our PFC to make meaning of all the different events we experience and to construct models for how to live our lives.
Somehow, though, this drive to make sense of the world around us, while it's given us so much we value, has also brought our civilization to the brink of collapse. How could this have happened? Is it an inevitable result of human nature, or is our present situation culturally driven: a product of particular structures of thought that could conceivably be repatterned?
The hierarchical structure of agrarian societies helped shape a new conception of the universe. In agrarian civilizations around the world, a HIERARCHY OF THE GODS emerged, stratified and distant from ordinary people, mediated by priests. People still viewed themselves as connected with the natural world, but now they believed their own active participation was required to keep the cosmos running.
The last common ancestor that humans shared with chimpanzees and bonobos is thought to have lived about six million years ago. In the evolutionary time scale, this is roughly the same time frame in which horses and zebras, lions and tigers, and rats and mice also shared their common ancestors.
As the trees became sparser, the hominids who were able to get around more easily on the ground were better adapted to the new terrain, leaving offspring who gradually became bipedal. Walking on two legs freed up the hands for new possibilities, such as holding sticks or throwing stones to defend against predators. Losing bodily hair allowed them to sweat more easily and stay cool in the hot sun.
the rivalry between males for sexual access to females continued to be a source of conflict within the group, occasionally leading to a breakdown in social cohesion. This rivalry would get especially intense over females seen to be ovulating. In those groups where the females’ overt signs of ovulation were diminished, the intergroup rivalry was lessened, with improved results for the groups’ long-term survival.
Perhaps the most important step in this understanding is the recognition that other people have minds like we do, and that, by thinking about how we ourselves respond to things, we can make predictions about how they might respond. This realization is known as “theory of mind,” and it forms the basis of much of our social existence.
In the view of an influential thinker, Richard Alexander, as hominids became more dominant in their ecology, they no longer needed to evolve better capabilities to deal with the natural environment. Instead, they developed new cognitive skills to outcompete each other.
Robert Trivers, was explaining how, from an evolutionary perspective, even altruism was really just a sophisticated form of selfishness, based on the principle of “I'll scratch your back and you scratch mine.” In a much-cited paper, he described what he called “reciprocal altruism” as an ancient evolutionary strategy that could be seen in the behavior of fish and birds, and he interpreted human altruism in the same way.
Responders, in fact, frequently reject offers below thirty dollars, and the most popular amount offered by proposers is fifty.20 It seems we humans have evolved a powerful sense of fairness. So powerful, in fact, that we would rather walk away with nothing than permit someone else to take unfair advantage of us.
This intrinsic sense of fairness is, in the view of some researchers, the extra ingredient that led to the evolutionary success of our species and created the cognitive foundation for values in our modern world such as freedom, equality, and representative government.
He discovered that, in virtually all hunter-gatherer societies, people join together to prevent powerful males from taking too much control, using collective behaviors such as ridicule, group disobedience, and, ultimately, extreme sanctions such as assassination. He names this kind of egalitarian society a “reverse dominance hierarchy” because “rather than being dominated, the rank and file itself manages to dominate.”
Around 2.5 million years ago, hominids began chipping away at stones to make tools that were sharper and more useful than ever before. These are known by archaeologists as Oldowan artifacts, after the Olduvai Gorge in East Africa where they were first found, and the species that produced them is called Homo habilis, or “handy man,” for their achievement.
These tools give archaeologists a good idea of how our ancestors might have procured their food. They would now have been able to dig up termite colonies or scavenge big game carcasses in the savannah, cutting through bones into the nutritious marrow. The extra calories available to them would have fueled the development of their larger brains, which demanded more metabolic energy. Their larger brains, in turn, gave them the social intelligence to thrive in their newly complex societies, creating a positive feedback cycle, leading to the evolution of even more powerful brains capable of

This entire sequence of steps would have required what is known in cognitive science as “mental time travel”: using one's imagination to create a vision of a hypothetical future—in this case, a future when it would be worthwhile to have a completed tool. With that future image beckoning, they developed a new capacity for self-control, suppressing other claims on their attention while focusing on the ultimate goal of constructing their tool.
The solution to this capacity constraint came in the form of a cognitive breakthrough that has allowed humans to think in a way that, most likely, no other creature on earth has ever achieved: symbolic thought. A symbol is something that has a purely arbitrary relationship to what it signifies, which can only be understood by someone who shares the same code.
perhaps the uniquely defining characteristic of humanity is the patterning instinct we evolved along the way, which allowed us to develop the capacity for symbolic thought, and which incessantly drives us to construct patterns of meaning in everything we experience. It's through these patterns that we're able to look back over our history and try to make sense out of it, to look forward to our future and try to direct where it will take us.
When humans talk, on the other hand, we are constantly linking words together to create meanings that emerge in new and sometimes unexpected ways. This combinatory power, which can create an infinite array of meanings from a finite set of words, is an essential part of language that sets it apart from the vervet calls and is known as syntax.
Based on the group sizes early humans probably lived in, they would have had to spend 30–45 percent of their day grooming to maintain social cohesion—probably an unsustainable amount of time. Gradually, mimetic forms of communication—gestures, grunts, and other vocalizations—would have become more significant, offering a more efficient form of social interaction than grooming, until finally developing into language.
language is far too intricate and rapidly changing for any combination of genes to have evolved to control for it specifically. It seems to make more sense to look for the underlying capabilities that evolved to enable language than to view language itself as a natural product of evolution.
