Reading List: A Short History of Man

Hoppe, Hans-Hermann. A Short History of Man. Auburn, AL: Mises Institute, 2015. ISBN 978-1-61016-591-4.
The author is one of the most brilliant and original thinkers and eloquent contemporary expositors of libertarianism, anarcho-capitalism, and Austrian economics. Educated in Germany, Hoppe came to the United States to study with Murray Rothbard and in 1986 joined Rothbard on the faculty of the University of Nevada, Las Vegas, where he taught until his retirement in 2008. Hoppe's 2001 book, Democracy: The God That Failed (June 2002), made the argument that democratic election of temporary politicians in the modern all-encompassing state will inevitably result in profligate spending and runaway debt because elected politicians have every incentive to buy votes and no stake in the long-term solvency and prosperity of the society. Whatever the drawbacks (and historical examples of how things can go wrong), a hereditary monarch has no need to buy votes and every incentive not to pass on a bankrupt state to his descendants.

This short book (144 pages) collects three essays previously published elsewhere which, taken together, present a comprehensive picture of human development from the emergence of modern humans in Africa to the present day. Subtitled “Progress and Decline”, the story is of long periods of stasis, two enormous breakthroughs, with, in parallel, the folly of ever-growing domination of society by a coercive state which, in its modern incarnation, risks halting or reversing the gains of the modern era.

Members of the collectivist and politically-correct mainstream in the fields of economics, anthropology, and sociology who can abide Prof. Hoppe's adamantine libertarianism will probably have their skulls explode when they encounter his overview of human economic and social progress, which is based upon genetic selection for increased intelligence and low time preference among populations forced to migrate due to population pressure from the tropics where the human species originated into more demanding climates north and south of the Equator, and onward toward the poles. In the tropics, every day is about the same as the next; seasons don't differ much from one another; and the variation in the length of the day is not great. In the temperate zone and beyond, hunter-gatherers must cope with plant life which varies along with the seasons, prey animals that migrate, hot summers and cold winters, with the latter requiring the knowledge and foresight of how to make provisions for the lean season. Predicting the changes in seasons becomes important, and in this may have been the genesis of astronomy.

A hunter-gatherer society is essentially parasitic upon the natural environment—it consumes the plant and animal bounty of nature but does nothing to replenish it. This means that for a given territory there is a maximum number (varying due to details of terrain, climate, etc.) of humans it can support before an increase in population leads to a decline in the per-capita standard of living of its inhabitants. This is what the author calls the “Malthusian trap”. Looked at from the other end, a human population which is growing as human populations tend to do, will inevitably reach the carrying capacity of the area in which it lives. When this happens, there are only three options: artificially limit the growth in population to the land's carrying capacity, split off one or more groups which migrate to new territory not yet occupied by humans, or conquer new land from adjacent groups, either killing them off or driving them to migrate. This was the human condition for more than a hundred millennia, and it is this population pressure, the author contends, which drove human migration from tropical Africa into almost every niche on the globe in which humans could survive, even some of the most marginal.

While the life of a hunter-gatherer band in the tropics is relatively easy (or so say those who have studied the few remaining populations who live that way today), the further from the equator the more intelligence, knowledge, and the ability to transmit it from generation to generation is required to survive. This creates a selection pressure for intelligence: individual members of a band of hunter-gatherers who are better at hunting and gathering will have more offspring which survive to maturity and bands with greater intelligence produced in this manner will grow faster and by migration and conquest displace those less endowed. This phenomenon would cause one to expect that (discounting the effects of large-scale migrations) the mean intelligence of human populations would be the lowest near the equator and increase with latitude (north or south). This, in general terms, and excluding marginal environments, is precisely what is observed, even today.

After hundreds of thousands of years as hunter-gatherers parasitic upon nature, sometime around 11,000 years ago, probably first in the Fertile Crescent in the Middle East, what is now called the Neolithic Revolution occurred. Humans ceased to wander in search of plants and game, and settled down into fixed communities which supported themselves by cultivating plants and raising animals they had domesticated. Both the plants and animals underwent selection by humans who bred those most adapted to their purposes. Agriculture was born. Humans who adopted the new means of production were no longer parasitic upon nature: they produced their sustenance by their own labour, improving upon that supplied by nature through their own actions. In order to do this, they had to invent a series of new technologies (for example, milling grain and fencing pastures) which did not exist in nature. Agriculture was far more efficient than the hunter-gatherer lifestyle in that a given amount of land (if suitable for known crops) could support a much larger human population.

While agriculture allowed a large increase in the human population, it did not escape the Malthusian trap: it simply increased the population density at which the carrying capacity of the land would be reached. Technological innovations such as irrigation and crop rotation could further increase the capacity of the land, but population increase would eventually surpass the new limit. As a result of this, from 1000 B.C. to A.D. 1800, income per capita (largely measured in terms of food) barely varied: the benefit of each innovation was quickly negated by population increase. To be sure, in all of this epoch there were a few wealthy people, but the overwhelming majority of the population lived near the subsistence level.

But once again, slowly but surely, a selection pressure was being applied upon humans who adopted the agricultural lifestyle. It is cognitively more difficult to be a farmer or rancher than to be a member of a hunter-gatherer band, and success depends strongly upon having a low time preference—to be willing to forgo immediate consumption for a greater return in the future. (For example, a farmer who does not reserve and protect seeds for the next season will fail. Selective breeding of plants and amimals to improve their characteristics takes years to produce results.) This creates an evolutionary pressure in favour of further increases in intelligence and, to the extent that such might be genetic rather than due to culture, for low time preference. Once the family emerged as the principal unit of society rather than the hunter-gatherer band, selection pressure was amplified since those with the selected-for characteristics would produce more offspring and the phenomenon of free riding which exists in communal bands is less likely to occur.

Around the year 1800, initially in Europe and later elsewhere, a startling change occurred: the Industrial Revolution. In societies which adopted the emerging industrial means of production, per capita income, which had been stagnant for almost two millennia, took off like a skyrocket, while at the same time population began to grow exponentially, rising from around 900 million in 1800 to 7 billion today. The Malthusian trap had been escaped; it appeared for the first time that an increase in population, far from consuming the benefits of innovation, actually contributed to and accelerated it.

There are some deep mysteries here. Why did it take so long for humans to invent agriculture? Why, after the invention of agriculture, did it take so long to invent industrial production? After all, the natural resources extant at the start of both of these revolutions were present in all of the preceding period, and there were people with the leisure to think and invent at all times in history. The author argues that what differed was the people. Prior to the advent of agriculture, people were simply not sufficiently intelligent to invent it (or, to be more precise, since intelligence follows something close to a normal distribution, there was an insufficient fraction of the population with the requisite intelligence to discover and implement the idea of agriculture). Similarly, prior to the Industrial Revolution, the intelligence of the general population was insufficient for it to occur. Throughout the long fallow periods, however, natural selection was breeding smarter humans and, eventually, in some place and time, a sufficient fraction of smart people, the required natural resources, and a society sufficiently open to permit innovation and moving beyond tradition would spark the fire. As the author notes, it's much easier to copy a good idea once you've seen it working than to come up with it in the first place and get it to work the first time.

Some will argue that Hoppe's hypothesis that human intelligence has been increasing over time is falsified by the fact that societies much closer in time to the dawn of agriculture produced works of art, literature, science, architecture, and engineering which are comparable to those of modern times. But those works were produced not by the average person but rather outliers which exist in all times and places (although in smaller numbers when mean intelligence is lower). For a general phase transition in society, it is a necessary condition that the bulk of the population involved have intelligence adequate to work in the new way.

After investigating human progress on the grand scale over long periods of time, the author turns to the phenomenon which may cause this progress to cease and turn into decline: the growth of the coercive state. Hunter-gatherers had little need for anything which today would be called governments. With bands on the order of 100 people sharing resources in common, many sources of dispute would not occur and those which did could be resolved by trusted elders or, failing that, combat. When humans adopted agriculture and began to live in settled communities, and families owned and exchanged property with one another, a whole new source of problems appeared. Who has the right to use this land? Who stole my prize animal? How are the proceeds of a joint effort to be distributed among the participants? As communities grew and trade among them flourished, complexity increased apace. Hoppe traces how the resolution of these conflicts has evolved over time. First, the parties to the dispute would turn to a member of an aristocracy, a member of the community respected because of their intelligence, wisdom, courage, or reputation for fairness, to settle the matter. (We often think of an aristocracy as hereditary but, although many aristocracies evolved into systems of hereditary nobility, the word originally meant “rule by the best”, and that is how the institution began.)

With growing complexity, aristocrats (or nobles) needed a way to resolve disputes among themselves, and this led to the emergence of kings. But like the nobles, the king was seen to apply a law which was part of nature (or, in the English common law tradition, discovered through the experience of precedents). It was with the emergence of absolute monarchy, constitutional monarchy, and finally democracy that things began to go seriously awry. In time, law became seen not as something which those given authority apply, but rather something those in power create. We have largely forgotten that legislation is not law, and that rights are not granted to us by those in power, but inhere in us and are taken away and/or constrained by those willing to initiate force against others to work their will upon them.

The modern welfare state risks undoing a thousand centuries of human progress by removing the selection pressure for intelligence and low time preference. Indeed, the welfare state punishes (taxes) the productive, who tend to have these characteristics, and subsidises those who do not, increasing their fraction within the population. Evolution works slowly, but inexorably. But the effects of shifting incentives can manifest themselves long before biology has its way. When a population is told “You've made enough”, “You didn't build that”, or sees working harder to earn more as simply a way to spend more of their lives supporting those who don't (along with those who have gamed the system to extract resources confiscated by the state), that glorious exponential curve which took off in 1800 may begin to bend down toward the horizontal and perhaps eventually turn downward.

I don't usually include lengthy quotes, but the following passage from the third essay, “From Aristocracy to Monarchy to Democracy”, is so brilliant and illustrative of what you'll find herein I can't resist.

Assume now a group of people aware of the reality of interpersonal conflicts and in search of a way out of this predicament. And assume that I then propose the following as a solution: In every case of conflict, including conflicts in which I myself am involved, I will have the last and final word. I will be the ultimate judge as to who owns what and when and who is accordingly right or wrong in any dispute regarding scarce resources. This way, all conflicts can be avoided or smoothly resolved.

What would be my chances of finding your or anyone else's agreement to this proposal?

My guess is that my chances would be virtually zero, nil. In fact, you and most people will think of this proposal as ridiculous and likely consider me crazy, a case for psychiatric treatment. For you will immediately realize that under this proposal you must literally fear for your life and property. Because this solution would allow me to cause or provoke a conflict with you and then decide this conflict in my own favor. Indeed, under this proposal you would essentially give up your right to life and property or even any pretense to such a right. You have a right to life and property only insofar as I grant you such a right, i.e., as long as I decide to let you live and keep whatever you consider yours. Ultimately, only I have a right to life and I am the owner of all goods.

And yet—and here is the puzzle—this obviously crazy solution is the reality. Wherever you look, it has been put into effect in the form of the institution of a State. The State is the ultimate judge in every case of conflict. There is no appeal beyond its verdicts. If you get into conflicts with the State, with its agents, it is the State and its agents who decide who is right and who is wrong. The State has the right to tax you. Thereby, it is the State that makes the decision how much of your property you are allowed to keep—that is, your property is only “fiat” property. And the State can make laws, legislate—that is, your entire life is at the mercy of the State. It can even order that you be killed—not in defense of your own life and property but in the defense of the State or whatever the State considers “defense” of its “state-property.”
