The Location of Human Knowledge

“The average forager had wider, deeper, and more varied knowledge of her immediate surroundings than most of her modern descendants,” writes Yuval Noah Harari in Sapiens. Individual human hunter-gatherers had to know a lot about their environment, and they were not learning from text books and schools. They were learning by trial and error, by being shown what was edible and what was not edible older members of their tribe, and they had to develop a plethora of skills in order to do all the things necessary for survival.
Humans today are not very likely to be able to weave baskets from reeds (as much as we joke about basket weaving courses for college athletes). They also likely can’t sharpen a flint arrowhead, don’t know what animals are around their location and how to hunt them, and don’t know what wild plants are helpful or harmful. Individually, modern humans don’t seem to have the same regionalized knowledge as the ancient humans that came before them. But today we definitely know far more than the humans before us as a whole.
The difference, Harari explains, is that the location of human knowledge has changed. We no longer all hold the same helpful regional information in our heads. Instead, we have a collective knowledge spread across humanity. Each of us is an expert in our own little niche. For example, I studied political science and Spanish. I know a bit about theories of policy processes, such as the Multiple Streams Framework, and I know a bit about medieval literature from the Iberian Peninsula. On the other hand, I don’t really know much about how nuclear submarines work, how my city’s sewage system works, and I don’t really know what migratory birds can be found in the area during the spring versus the fall. Someone else in the collective of human knowledge is an expert in each of those things.
“The human collective,” writes Harari, “knows far more today than did the ancient bands. But at the individual level, ancient foragers were the most knowledgeable and skillful people in history.” This quote may be a broad overgeneralization, but it is nevertheless interesting and thought provoking. Some of us are incredibly skilled with a variety of things and have a great deal of knowledge about much of the world around us. Others don’t seem to have as much skill, and know more about celebrities than we do about what is happening in the world. Overall, the important thing to consider is that the modern world has seen a shift in the distribution of knowledge. We don’t all have to hold information about our immediate surroundings in our heads, and we don’t all have to be able to produce the things necessary for our survival. Only some humans need to know those things and have the skills to produce the basic necessities for life. The rest of us can then go off and explore different areas and learn different things, constantly increasing the collective human knowledge and skill base, even if we individually seem more narrowly skilled and less immediately knowledgeable compared with our ancient forager ancestors.
There is no Natural Way of Life - Yuval Noah Harari - Sapiens - Joe Abittan

There is No Natural Way of Life

Are human beings naturally peaceful, or naturally violent? Are they naturally traders, or are they naturally competitors? Is it natural for them to pursue progress, or natural for humans to stick to tradition and avoid new ways of organizing the world around them? These questions rage every day in academic circles, on the news, in our offices, and everywhere that people gather. We like to believe that there are things that are simply natural for human beings, and things we consider natural are considered broadly good, while things that are unnatural are lumped in with everything bad and evil.
However, in his book Sapiens, Yuval Noah Harari argues that there is no natural way of life for Homo sapiens. Instead, according to Harari, there is a wide horizon of possibilities which includes, “…the entire spectrum of beliefs, practices, and experiences that are open before a particular society, given its ecological, technological, and cultural limitations.” Even for people living in the most remote, technologically limited, and culturally strict villages on Earth, there is a wide horizon of possibilities for what any individual or group could do. For those of us lucky enough to live in the United States, the horizon of possibilities is effectively endless. The ways in which we could live and experience the world are greater than what any of us could imagine, and all the different perspectives and permutations could be considered natural from a certain point of view – or unnatural from another. Trying to attach values such as good or bad, through labels of natural or unnatural, doesn’t really make sense for any given permutation chosen from the horizon of possibilities.
Harari continues, “The heated debates about Homo sapiens’ ‘natural way of life’ misses the main point. Ever since the Cognitive Revolution, there hasn’t been a single natural way of life for Sapiens. There are only cultural choices, from among a bewildering palette of possibilities.” Dating back at least 70,000 years ago, human tribes have varied and differed based on numerous factors. Looking at a single ancient tribe or group of humans and deciding that how they lived was natural gives us a misleading understanding of how we should live today. We can look back and find tyrannical leaders who conquered other tribes and sacrificed their victims to their gods, but this doesn’t mean it is natural for humans to be lead by a single genocidal tyrant. It is just as fair to look around today and see transsexual men and women cooperating and sharing virtual resources in a video game and make conclusions about what is natural for humans as it would be to look back at the genocidal tyrant, to look back at human groups from the days of the first books in the Christian Bible, or to look back at any other group of humans from any part of the globe since the Cognitive Revolution and decided that how people live, interact, behave, and interpret the world is ‘natural’. At each point in space and time there are options available to us based on the ecology of where we find ourselves, based on the technology and knowledge available to us, and based on many other factors we cannot enumerate. Some ways of living are more likely to help us and others survive, some ways of living are more likely to help us enjoy our lives, but that doesn’t mean they are natural, good, or will continue to help us survive and enjoy our lives indefinitely. There is no natural way of life for a human, only a staggeringly large set of possibilities.
The Wood Age

The Wood Age

An interesting bias that enters into our understanding of the world and human history comes from material sciences. When we look into the deep human past, we have very weak evidence upon which we can base our assumptions and theories. Before people wrote things down, we didn’t have anything that could preserve the history of a people or place. And even once people began to record things it was still hard to save those recordings for the long term. We have some stone and clay tablets with inscriptions on them, some quipus (string counting devices), and some written documents on animal skin, but not a lot of well preserved, documented writing from the earliest known humans to have settled into communities. Most of the artifacts we have from early humans come from any stone tools they used, because those can be preserved better.
Yuval Noah Harari writes about the bias these stone tools create in his book Sapiens. “The common impression that pre-agricultural humans lived in an age of stone is a misconception based on this archaeological bias. The Stone Age should more accurately be called the Wood Age, because most of the tools used by ancient hunter-gatherers were made of wood.”
I think it is interesting to consider our bias of ancient humans based on the materials we can recover of their history. The Stone Age is a common idea that appears in cartoons, in advertisements, and in stories. But it is understandable that early humans would have used wood more than stone for many tools. Wood is lighter, can be shaped more easily, and may be more available than stone in some parts of the world – not for me personally here in Northern Nevada. The Stone Age bias is a simple bias that we never think about unless we are asked to stop and consider the way that materials and artifacts could bias our minds. It is an accepted story and idea that we share, without even realizing the bias taking place.
Thoughts on Monogamy - Evolutionary Psychology & Becoming WEIRD

Thoughts on Monogamy – Evolutionary Psychology & Becoming WEIRD

Monogamy doesn’t seem to be the natural way for humans to live. Very few species mate with a single partner for life, and while humans in most parts of the world do, it is often not done well. Romantic affairs are the driving plot device in more books and movies than any of us can count. In the real world, we know plenty of people who have cheated on spouses or significant others, or been on the other side of the cheating. Numerous TV show hosts have made a living  by revealing the results of paternity tests.
Yuval Noah Harari makes a suggestion in his book Sapiens that monogamy is so hard for humans today because most of human evolution was not focused on monogamous relationships. Nuclear families are a relatively recent invention. For most of human history, we lived in small social tribes, and raising a child wasn’t the responsibility of two parents who who married and stayed together for the rest of their lives. In some instances, tribes actively practiced fatherhood rituals that were the direct opposite of monogamy. Harari writes,
“The proponents of this ancient commune theory argue that frequent infidelities that characterize modern marriages, and the high rates of divorce, not to mention the cornucopia of psychological complexes from which both children and adults suffer, all result from forcing humans to live in nuclear families and monogamous relationships that are incompatible with our biological software.” Harari describes the ancient commune theory mentioned in the quote as a theory that people in small tribes didn’t understand that a single man’s sperm fertilized an egg. It was not clearly understood that only one person sired a child, and in some tribes women would actively haved sex with multiple men, even throughout a pregnancy, so that her child would gain the qualities of all the men.
When I first read this quote from Harari it made me question whether modern monogamous marriages were really the best thing for humans.  If it contradicted our biology so much, I wondered why we kept it around, especially if it caused so many psychological, social, and emotional problems for so many people.
Joseph Henrich’s book The WEIRDest People in the World, helped me understand why monogamous institutions have become so useful in our modern world, despite the costs that Harari mentions and the incompatibility of monogamy with our evolutionary psychology. When societies do not have a system of single pair bonding, the highest status men tend to accumulate more females to exclusively marry. Regardless as to whether the women want to have sex with many men and partner with them, they often find that it is best for them to stick with just the one highest status man (possibly the wealthiest, strongest, or most politically connected man) for the best chance to raise their children. Pairing with a high status man who already has two or three other wives can often be more advantageous for a woman than pairing with the fourth most high status man, especially as women are pushed toward men further down the status ladder – as happens in strict monogamous societies.
As high status men accumulate more women who exclusively partner with them, even though the man doesn’t exclusively partner with the women, then lower status men do not find a partner. Single men who cannot get a partner are more likely to take large risks and gambles to try to move up the social ladder. They have more testosterone, because married men have a decrease in  testosterone, and they have less reason to invest in the future. Henrich argues that policies which pushed monogamy and broke up polygamy were a driving factor in what made the West WEIRD – Western, Educated, Industrialized, Rich, and Democratic. Monogamous societies help ensure more men are able to find a partner, decreasing the number of single men without prospects for getting married or having children. This  gave more men a reason to invest in the future and improve their behavior and cooperation with others.
Our monogamous relationships may not be in line with our biology, but they have encouraged a more even distribution of male and female partners, and have helped create more stable societies. The relationships are hard, but at least recently have been a driving force toward WEIRD progress and development. The cost of monogamy that stem from a reproductive and sexual system mismatched to our evolution and biology don’t outweigh the benefits of a more stable, peaceful, and fruitful society.
The World that we Subconsciously Still Inhabit

The World we Subconsciously Inhabit

Evolutionary psychology, and evolutionary explanations for modern day human behaviors, have become more popular recently. The argument is that much of what humans do today, some of which makes sense and some of which doesn’t seem to make sense, can be understood by looking into the distant human past and understanding how ancient humans lived. As Yuval Noah Harari writes in his  book Sapiens, “the flourishing field of evolutionary psychology argues that many of our present-day social and psychological characteristics were shaped during this long pre-agricultural era.” The era mentioned by Harari was the tens of thousands of years during which ancient humans lived in small bands as hunters and gatherers.
Humans lived with scarcity for tens to hundreds of thousands of years. Humans were not the most physically dominant and impressive species on the planet, didn’t often have a lot of food to eat, and didn’t have much security in terms of shelter or family. In such an environment, humans evolved specific genes to help them survive as relatively weak scavengers in small groups. But evolution for humans did not stop there. Cognitively, humans continued to improve and brains became more powerful, ultimately allowing humans to shoot up the dominance ladder, creating modern societies. Our new environment is dramatically different than the environment that almost all humans have lived in. Over a few hundred years we have created societies of abundance, of hundreds of thousands to millions of humans living together in close contact, and societies of impressive technological comfort. But evolution is much slower than our ascent, and has created challenges for us.
Regarding our modern environment and situation, Harari continues, “this environment gives us more material resources and longer lives than those enjoyed by any previous generation, but it often makes us feel alienated, depressed, and pressured. To understand why, evolutionary psychologists argue, we need to delve into the hunter-gatherer world that shaped us, the world that we subconsciously still inhabit.”
Harari explains that our bad habit of overeating sugary and greasy food becomes understandable if we look back at the environment that our human ancestors found themselves in and evolved through. Sugary food was rare. Ripe fruit, and greasy meat was hard to come by for a foraging species that couldn’t compete with larger animals to defend a downed antelope or tree full of figs. If a human did find a bunch of ripe fruit or a carcass that wasn’t being attended to by some hungry hyenas, then the human’s best bet was to eat as much as possible in one sitting. Today, in affluent societies, we have all the food we can want – we can even have it delivered to our door – but we still have the  genes that told our ancestors to eat as much as possible when sugary and greasy food was available. This mismatch doesn’t serve us well in the modern day, but the evolutionary psychology argument suggests that it was beneficial for survival in the past. Evolutionary psychology allows us to better understand ourselves today by exploring how our ancestors lived and what genetic pressures were placed on them. The challenge we now face, extending far beyond genes that influence our preference for foods, is that we no longer inhabit the world that our genes and bodies evolved to fit within. Subconsciously, and at an instinctual level likely influenced to a high degree by our genes, we still inhabit worlds that no longer exist. Our evolutionary past and psychology haven’t caught up with the modern world we live in, but we don’t always realize that is the case.
History and Culture

Culture and History

In Sapiens, Yuval Noah Harari writes, “The immense diversity of imagined realities that Sapiens invented, and the resulting diversity of behavior patterns, are the main components of what we call ‘cultures’. Once cultures appeared, they never ceased to change and develop, and these unstoppable alterations are what we call ‘history’.”
Across the globe humans have different ways of living, different ways of relating to each other, and different ways of understanding the universe. Harari would argue that many of  these differences stem from different realities invented at different times by different peoples across the globe. I would agree with him. We can argue over whether some differences are good or bad, whether some some differences are fair or unjust, and whether some differences reflect the nature of reality more or less accurately, but in the end, a great deal of what we call culture is more or less random, based on invented realities that fit the time.  History is the study of how these invented realities and associated customs and behaviors change.
I have written before about the fact that human rights do not exist. At least, and Harari would agree, they are not anything tangible that you could identify in the real world if you autopsied a human. Ultimately, human rights fall into the same category as spirits and the human soul. For many years humans investigated the human body, trying to find the soul, trying to weigh the soul as it left a dying human body, and trying to confirm that it was indeed a tangible thing. In the end, reasonable scientists had to conclude that the soul was an invented reality, not an objective reality, and human rights fall in the same category. They are an invention that we make real through institutions, customs, and behaviors. The idea of human rights helps us understand how we relate to each other and the systems and structures of governance that we have established in the United States. They have been helpful in organizing society and helping us develop, but that doesn’t necessarily mean they reflect a true reality about the universe, or that they always will serve humans well. They are a specific product of culture that has grown out of Western, educated, industrialized, rich, and democratic (WEIRD) societies.
Humans have not always had human rights, as we can see by studying and exploring history. Cultures, and the values that cultures cary, such as human rights, have altered through time. Harari argues that these changes are unstoppable, and that new invented realities are constantly arising to fit the new developments and needs of human beings. Much to the chagrin of those who lean toward conservatism, desiring a stasis rather than a progression, culture doesn’t stand still, the stories we invent about reality don’t stay the same. cultures move, invented realities morph, and history progresses. Ideas that serve us well in one cultural setting may not serve us well in the future, and may evolve into something entirely different.
Sapiens' Trade

Sapiens’ Trade

In the book Sapiens, Yuval Noah Harari discusses archaeological evidence that Homo sapiens engaged in trade tens of thousands of years ago. He also suggests that evidence of trade can be used to explain how Homo sapiens could have out competed other human species.
For example, Harari suggests that Neanderthals probably couldn’t cooperate to the same extent as sapiens. He also suggests that a Neanderthal would win in a fight with a Sapiens, but that individual fights between human species was not the main form of competition. Large numbers of Sapiens could communicate and share goals through myths and stories, allowing them to gang up on stronger species like Neanderthals. Comparing the cognitive level of the two species, Harari explains how differences in trade support ideas of different levels of cognition, and the advantages that Sapiens had:
“Archaeologists excavating 30,000-year-old Sapiens sites in the European heartland occasionally find there seashells from the Mediterranean and Atlantic coasts. In all likelihood, these shells got to the continental interior through long-distance trade between different Sapiens bands. Neanderthal sites lack any evidence of such trade. Each group manufactured its own tools from local materials.”
Sapiens and Neanderthals were both tool users, but Sapiens appeared to be traders with foreign bands. While Neanderthals constructed all their tools themselves, Sapiens could get different tools from different bands, could get decorative seashells, and could coordinate and cooperate among themselves and others. This communication and cooperation is what Harari argues gave Sapiens an advantage over species like the Neanderthals, and what eventually allowed Sapiens to outcompete other species and ultimately become modern Homo sapiens.
