This chapter explains the philosophical and scientific principles that will be the basis of our study of social change.It provides an overview of different theoretical approaches and the basic concepts of institutional materialism, the sociological perspective to social change that is employed in the rest of the book.

Science and Objectivity

The scientific study of social change is not as straight-forward as studying rocks or frogs.If we were extra-terrestrials sitting on the moon observing Earthlings through a telescope it would not be hard to attain a high level of objectivity.But each of us is a human speaker of a particular language living in a specific place with a head full of a particular cultural heritage and standing in a certain relationship with the rest of the occupants of our planet. We are men or women, American or Chinese, from New York or Bombay, Catholic or Moslem, Republicans or Greens, Hunt Club or Bowling League. Objectivity is a key requirement of science, and yet we are trying to be objective about ourselves and our own history.Some think that the enormity of this problem means that social science is impossible, and so we should just surrender to subjectivity and enjoy it.But another path is to try to attain a sufficient degree of objectivity by becoming aware of the sources and strengths of our prejudices.To do this we need to understand how science itself is a cultural product and how scientists are influenced by social processes.We need to place ourselves in historical perspective and then to use that understanding as a basis for examining our own biases. We need to be clear what the goals of social science are, even if they are unreachable in any absolute sense.

It has been said that science should be value-free in the sense that scientists should try to ascertain the objective truth without allowing their beliefs about good and evil to influence their judgments about what is true. I will maintain this distinction in what follows.But science also has its own values. It is a philosophical venture that has its own goals, which are themselves taken on faith, or at least they are provisionally accepted. When we play chess or basketball we agree to operate on the basis of the rules of the game.When we do science it is likewise. The philosophical presuppositions of science are not themselves provable by means of science. Instead, they are values that we may choose to affirm and defend.

The main goals of the scientific study of social change are to understand the truth about what happened in the human past and to build explanations of the patterns of human behavior and social institutions. These explanations should be objectively testable, relatively elegant (simple), and powerful in the sense that theoretical propositions account for a lot of the patterns of social change that can be observed.

Causal propositions can be evaluated using the comparative method (see below).Explanations will probably never be perfect, but scientific progress means better and better approximations of the way social change actually works.

Ideally this enterprise should approach social change from an Earth-wide perspective rather than from the point of view of any particular society or civilization. Modern science emerged from the European Enlightenment’s encounter with the rest of the world during the rise of European hegemony. This historical fact must be acknowledged and examined in order for it to be transcended by a truly Earth-wide science of social change. 

Social science should also be objective with respect to the focus on human beings in relationship to other forms of life.Humanism is a fine ethical point of view, but social science should not presume that the human species is superior to other life forms.As social scientistswe should focus on the human species without making any presumptions about the value of that species for good or ill.Some scientists study amphibians and others study humans. 

Humanism And Values

But that is not all. In addition to being scientists we are citizens, as well as members of families and communities. Every scientist is also these other things, and good social science can be helpful for pursuing the goals that are associated with these other roles.The idea here is that each of us plays more than one game, and we need to be clear about which rules are which.A person who is a social scientist during the day is a parentand a citizen by night – s/he wears more than one hat. But the operations of one game may have implications for another.

The main focus of this book is to present the best current practices of the science of social change, but in the final chapter we will go beyond social science to suggest how what we know might be used to bring about a more humane and sustainable world society.As a citizen I am a humanist, so I will affirm that the survival of the human species is a desirable goal.This does not contradict what I have said above about my scientific goals.My political and social valuesare choices and commitments that I have made, and I recognize that these cannot be proven by science.But science may provide useful information for realizing political and philosophical goals. Indeed almost all modern political philosophies make appeals to science for support of their views of human nature and the possibilities for human society.The important thing here is to not put the cart before the horse.In this text the science is first.

Science need not claim to be the only valid perspective on ultimate reality. In asserting the value of the scientific approach against religious systems of thought early scientists often took an arrogant stance that belittled other approaches to reality. Now that science itself is the main religion of the emerging global culture a more agnostic and tolerant philosophical stance is desirable, though this need not go to the extremes of cultural relativism and subjectivism advocated by many of the postmodernists.Science can be modest and useful without the arrogance of scientism.

The Comparative Method

All science is based on the comparative method in the sense thatcausality is inferredby comparing sequences of events. When it is possible to manipulate the processes under study scientists do true experiments because causal inferences can be made more reliable by isolating and simplifying the operation of variables.If we want to know whether A causes X we can experimentally manipulate A and see what happens to X and isolate X from other influences. In most of social science it is not feasible to carry out true experiments, but we can still employ the logic of the experimental method in order to make inferences about causality.Thus we design our research as if we were manipulating variables and we look for opportunities in nature in which processes seem to be simplified and isolated.We measure variables A and X and see if, in the course of events,a change in A seems to regularly correspond with a change in X.Or we observe a number of comparable cases and see if there is a patterned relationship between A and X that might indicate causality. We can also measurevariation in other variables to try to infer how they may be involved in the relationship between A and X.

The comparative method allows us to infer causality, albeit with varying degrees of certitude.We choose comparable cases or instances of the processes of social change we care about, and then we measure the variables that we think are causing the main (dependent) variable of interest, and we test causal propositions by studying variation over space or time (or both).Whether we study one case over time or several comparable cases we are employing the comparative method and the strategy of quasi-experimental research design.

Figure 1.1:Does A Cause X?

We use probabilistic logic rather than deterministic logic in our models of social change.A probabilistic statement says that A is likely to cause X a certain percentage of the time. There is an explicit element of randomness or indeterminacy.A deterministic statement says that A always causes X.We use probabilistic logic for two reasons:

1. because there is usually error in our measurements of variables, and

2. because social action is itself probabilistic rather than deterministic.

Thus we do not speak of “laws” of social change, but rather of causal tendencies.

Probabilistic logic is also used in much of natural science, but it is even more important to use it in social science because we are trying to predict and explain the behavior of intelligent beings.The amount of indeterminacy in the behavior of a billiard ball is considerably less than the amount of indeterminacy in the behavior of a person.If you tell a billiard ball your prediction of the path it will take after bouncing off the side of the pool table, your statement cannot affect the behavior of the ball. But if you tell a voter that she is likely to vote for the Bullmouse Party your prediction may influence her decision. Intelligent beings are difficult subjects of scientific study. We need to take these special problems into account in our efforts to explain and predict what humans do.So we use probabilistic statements and we try to comprehend the ways in which our subjects interpret their own worlds.

Types of Evidence

The evidence that we use to study social change over the long run is of several different kinds.For studying people who lived before the invention of writing we use archaeological evidence – the remains of peoples’ lives as found in artifacts, evidence of what they ate, how they constructed their habitations, the sizes of settlements. The ability to accurately date artifacts is an important method for understanding sequences of development and what was going on at the same time in different regions.We can often infer a great deal about patterns of trade and interaction from the distributions of artifacts for which the original sites of procurement can be determined. For example, volcanic glass (obsidian) can be chemically “finger-printed” so that it is possible to know that a particular obsidian arrowhead originally came from a quarry far from where the arrowhead was found.By studying the composition of arrowheads at a site we can see how trade and procurement patterns changed over time. We can sometimes find archaeological evidence of proto-money, the use of certain trade items as generalized media of exchange.Archaeological evidence cannot tell us directly about what people thought or felt, but we can make educated guesses about their social organization based on the remnants that human occupation leaves. 

Ethnographic evidence is that information that has been gathered by anthropologists who have studied people who live in less complex societies that survived until the nineteenth and twentieth centuries.The ethnographers moved in with the remaining hunter-gatherers and tribal peoples of the nineteenth and twentieth centuries to study their languages, and their material and ideological cultures.The greatest use of this corpus of evidence for the study of social evolution is the light that it sheds on the lives of people who lived thousands of years ago, but it is important to realize that hunter-gatherers who managed to survive until recently may not accurately represent of hunter-gatherers who lived long ago.Obviously those who have been long in contact with more complex societies are likely to have adapted to these interactions in important ways that change the nature of their institutions.The usage of ethnographic evidence to supplement archaeological evidence needs to be cautious regarding this problem.

It is often possible to use the written observations and records made by the first literate observers of preliterate peoples (missionaries, etc), though these sources of information are usually heavily biased by the civilizational perspectives of the observers. Once societies have developed writing we can decipher their own written records and documents as sources of evidence about social institutions and practices. The firstwritten languages emerged along with the original invention of states in Mesopotamia about 5000 years ago.Records and documents were written on clay tablets that preserve rather well under dry conditions. Ironically, the development of papyrus documents in later millennia created a larger hole in the evidence because papyrus is more fragile than clay tablets. Our documentary knowledge of the great Persian Empire of the Achaeminids is largely confined to epigraphs, inscriptions on stone monuments, because the papyrus documents have decayed.We use documentary evidence in conjunction with archaeological evidenceto gain an understanding of the early civilizations. We also see the development of formal systems of money and can infer much about ancient economies and polities by studying coinage.

Ancient states began to gather systematic evidence about their own finances and the populations under their control. This evolved into the modern system of statistics,censuses and national accounts that we use as evidence of social change. Sample surveys and systematic studies of large populations allow us to be much more thorough andprecise about social changes that have occurred in the last half century.We can now use satellite data to study large-scale social processes such as urbanization and global deforestation.

Social Evolution

Social evolution is most simply the idea that social change is patterned and directional – that human societies have evolved from small and simple affairs to large and complex ones. The idea of social evolution has had a rough career in social science and it is still in disrepute in some circles. Part of the problem has been that earlier formulations of the idea embodied certainassumptions that are unscientific in nature. The idea that some human societies are superior to others because they are “more advanced”has been used as a justification by some people for dominating and exploiting others. The social evolutionism of the British anthropologists of the nineteenth century presented London society as the highest form of civilization and depicted colonized peoples as savages and barbarians. Evolutionary ideas were used to support a philosophy of social Darwinism in which the current winners were depicted as better adapted and loserswere portrayed as on the way to extinction because of genetic and/or cultural deficiencies. More recently Talcott Parsons’s (1966) version of structural/functional evolution presented the United States in a similar light.

In reaction to these problems many social scientists embraced a radical cultural relativism in which each society was understood as a unique constellation of institutional practices.It was assumed that there were no inherently superior social structures, but rather that all human cultures were equal, though different from one another. The ethnographer Franz Boas was the greatest proponent of this approach and modern anthropology was heavily influenced by his stress on careful fieldwork that recorded the linguistic, spiritual and material attributes of human societies.The ethnographic corpus produced by following Boas’sapproach is a vast resource for our knowledge of ways of life different from our own despite the cultural biases and problems of objectivity of those who have “tented with the natives.”But the rejection of social evolutionism has ebbed as the elements that made it obnoxious have been separated from the more basic notions of patterned and directional change (Sanderson 1990).

There were three main problems with social evolutionary thinking thatneeded to be rectified:

1.Social evolution is easilyconfused with biological evolution, and yet these are largely distinct and different processes. 

2.Evolutionary thinking has tended to involve teleological assumptions in which the purposes of things have been asserted to be their cause.

3.Evolution has been confused with the idea of progress – the notion that things are getting better.

Social vs. Biological Evolution

Social evolution and biological evolution are different processes, though they share some similar characteristics.Confusing these processes causes great misunderstanding and facilitates theoretical reductionism in which social science is subsumed as a sub-branch of biology.While biological evolution is based on the inheritance of genetic material, social evolution is based on the development of cultural inventions.Both genes and cultural codes are information storage devices by which the experiences and outcomes of one generation are passed to future generations.Social evolution did not exist before the invention of culture.Animals that do not have the biological ability to manipulate symbols and to communicate them do not experience the process of social evolution.The human animal is uniquely equipped to evolve socially because of the presence of the relatively large unpreprogrammedcortex of the human brain. This unusual piece of equipment makes possible the learning of complex codes and their infinite recombination. 

Humans have a lot of RAM relative to ROM, whereas non-human animals have more ROM than RAM. In computers RAM is RANDOM ACCESS MEMORY that can contain changeable software, whereas ROM is READ-ONLY MEMORY that is permanently programmed at birth. This is another way of saying that humans are less instinctual than non-humans.Ants live in large and complex societies, but their behavior in these is largely instinctive. Their social structures are hard-wired, and the architecture of their mounds is rigidly bound by theinstinctive behaviors of mound-building. Humans learn the cultural software that enables them to build large and complex societies and the plan is coded in language and blueprints that may be modified without having to wait for the evolution of new instinctive behaviors.Language itself has an instinctive basis and this is why speakers of all natural languages share a somewhat similar grammatical structure. But this biological ability makes possible the great variation that we see in meaning systems and social institutions.

When nomadic hunters developedstone tools they obviated the need to genetically select for carnivorous teeth.Thus cultural evolution allowed humans to occupy new niches and to adapt in new ways without waiting for biological evolution. This slowed down the rate of already-slow biological evolution of human genes.

The similarities between biological evolution and social evolution are these: 

·both rely on information storage to pass the experiences of one generation on to another; 

·both are mechanisms whereby individuals and groups adapt to changing environments or exploit new environments;

·in both more adaptive changes drive out less adaptive characteristics through competition.

·And there is onemore similarity. In both biological and social evolution more complex systems develop out of simpler systems.

There are, however, rather large and important differences between biological and social evolution:

·In biological evolution the source of innovations is the random process of genetic mutation, while in social evolution recombinations and innovations occur intentionally as people try to solve problems.This is not to say that social evolution is entirely rational or even intentional, because many social changes occur as the unintended consequences of the actions of many individuals and groups. But the important point here is that, compared with genetic mutation, social innovation contains an important element of intentionality. 

·The second big difference is in the rate of change. Biological evolution takes a long time, while social evolution is much faster and is accelerating. Biological evolution occurs slowly because it is dependent on mating and reproduction and on those few unusual genetic mutations that are adaptive.Social evolution is accomplished by means of cultural inventions, and these can spread from group to group. Societies can “mate” and exchange cultural material, whereas species cannot exchange genetic material. 

·Another important difference is in the relationship between simpler and more complex forms.In biological evolution simple one-celled forms of life co-evolve along with more complex multi-celled organisms.Indeed, they seem to thrive. Viruses and bacteria are doing just fine. In social evolution the situation is vastly different. Small scale societies get wiped out by larger societies. There is not co-evolution of small and large. Rather states and empires destroy stateless societies(.e.g hunter-gatherer bands) by either killing off their members or by assimilating them into state-based societies, or both.The history of the indigenous Americans is a case at hand.Anthropologists have termed this the “law of cultural dominance.”It is not anatural law in the sense that it is impossible for more powerful cultures to allow less powerful ones to survive, but this has not happened to any appreciable extent.

So cultural and biological evolution are quite different processes, and it is important to understand this distinction because the word “evolution” is often used in ways thatcause confusion.Many of the claims of sociobiology and evolutionary behaviorism are exaggerations of the extent to which human actions are instinctive and based on biological evolution. The idea of human nature is itself a culturally constructed notion that has powerful effects in legitimating social institutions.And yet, to argue that human behavior is less instinctive than the behavior of other animals does not require that we deny the biological basis of human actions. There are clearly constraints, as well as possibilities, that emanate from our bowels and our brain-stems.But social and cultural evolution has radically reconstructed these constraints. 

Regarding the relationship between biological and social evolution, it is obvious that there would have been no cultural evolution if the human species had not evolved the ability to speak and a brain capable of storing and reconfiguring complex codes and symbols.These were the key developments that allowed culture to emerge.Once culture emergedit acted back upon biological evolution.Social structure has taken over as a main source of influence over which humans and otherlife forms survive and prevail. Domestication of certain animals and plants, selective breeding, and now the development of genetic surgery, cloning and genetic engineering have massively affectedbiological evolution on Earth, and this impact will only become greater if the human species survives its own experiments. 

Teleology and Unilinear Evolution

Teleology is a form of explanation in which the purpose of a thing is alleged to be its cause.The most famous teleological explanation is that order in the universe is a consequence of the will of God. Aristotle contended that all of nature reflects the purposes of an immanent final cause.The problem is that general purposes of the universe cannot be scientifically demonstrated to exist. Science is limited to knowledge of proximate causation. The causes of a thing must be demonstrably present or absent in conjunction with the presence or absence of the thing to be causally explained.Proving causality requires variation. General statements about characteristics of the universe that are invariably present cannot serve as scientifically knowable causes precisely because they do not vary. 

A related unscientific characterization of historical processes is inevitabilism or the idea that history is the result of an unfolding process in which stages follow one from another in a necessary order, like the pages of a book.Another term for this kind of theory is unilinear evolution.Much of the rhetorical power of Marxism came from the stage theory of history which alleged that socialism and communism would inevitably supersede capitalism. Thus hard-working revolutionaries could claim to have history on their side.Now, ironically, Marxism has itself been thrown into the dustbin of history and the ideologues of capitalism claim that socialism is an outdated ideology that was produced by the strains of transition from traditional to modern society and global capitalism. All stage theories need to be treated with skepticism, but this does not mean that we should abandon the effort to see the patterns of social change.

The probabilistic approach to social change outlined above disputes the scientific validity of inevitabilism or unilinear evolution. This is not the same as arguing that there are no directional patterns of social change or that all outcomes are equally probable. But it is important to know that scientific social change theory is about probabilities,not inevitabilities.Social evolution has not been a process in which a single society goes through a set of stages to arrive at the most developed point. It has been uneven in space and time. Societies that are at the highest level of complexity at one point often collapse and the emergence of larger, more hierarchical and more complex societies occurs elsewhere.Indeed, this uneven pattern is one of the most important processes in the evolution of world-systems.

A scientific approach to social evolution does not assert final causes or ultimate purposes. It proposes causal propositions that are empirically testable and falsifiable with evidence about human history and social change.Neither does social evolution claim that particular outcomes are inevitable.Contingency and unexpected events can alter the course of human history fundamentally. The fate of the dinosaurs, probably destroyed by the impact on Earth of a large asteroid, powerfully reminds us about the potential importance of unexpected events that come from elsewhere. But this should not prevent us from trying to see the more likely patterns of development in both the past and the future, or the trajectories that social change will take in the absence of catastrophic events.

Progress and Social Evolution

Progress is not a scientific idea in itself because it involves evaluations of the human condition that are necessarily matters of values and ethics.The idea that a world populated by humans is better than a world in which they are absent is an esthetic or ethical matter of choice.Even the idea that warm and well-fed humans are better off than cold and hungry ones, or that long, healthy life is better than shortdisease-ridden existence --these too are value choices, albeit ones that would be widely agreed upon by most people. When we turn to matters of religion,family form, cuisine, or the ideal degree of social equality it is more obvious that we have entered the world of value decisions.One of the biggest problems with many theories of social evolution is that they have tended to be permeated with assumptions about what is better and worse and many have simply assumed that evolution itself is a movement from worse to better.And with this powerful element embedded in them evolutionary theories have served as potent justifications of conquest, domination and exploitation. We have already pointed out that this problem was the main one that led the second generation of anthropologists to reject social evolutionism in favor of a strong dose of cultural relativism.

Theories of progress are still important ideological elementsin the world of politics, and so ideas about social evolution are still susceptible to being used badly. But so are other products of science and humanistic endeavor.Physicists are painfully aware of how the knowledge they have produced has been turned into the threat of nuclear holocaust.Historians, even those who studiously avoid makinggeneralizations about the human predicament, may find their interpretations of historical events turned to uses of which they disapprove.Neither scientists nor humanists can control the usage to which their works are put.

This said, if we agree on a list of desirable ends that constitute our notion of human progress, then it can be a scientific question as whether things have improved with respect to this list, or which kind of society does better at producing the designated valuables.The list is one of preferences, not scientifically determinable, but philosophically chosen. This list may be my personal preferences, or some collectively agreed upon set of preferences. This approach to the problem of progresswill be considered near the end of this book when we ask about the implications of our study of social change for world citizens.

The notion that it is plausible to formulate general theories of social evolution is given credence by the observation that many instances of parallel evolution have occurred. Parallel evolution means that similar developments emerge under similar circumstances, but largely independently of one another.If horticulture (planting) had only been invented once and then had diffused from its single place of invention it might be argued that this was merely a fortuitous accident. But horticulture was invented independently several times in regions far from one another. Similarly states and empires emerged in both the Eastern and Western hemispheres with little interaction between the two despite that the emergence of states in the Western hemisphere occurred some three millennia later than in the Eastern. It is also quite likely that the emergence of states in East Asia, near the bend of the Yellow River in what is now China, occurred largely independently of the earlier emergence of states in West Asia, in the region that we call Mesopotamia (now Iraq). The significance of important instances of parallel social evolution is that they imply that general forces of social change are operating. Our task is to determine with evidence which conditions and tendencies were the most important causes of these developments.

Idiographic Historicism vs. Nomothetic Ahistoricism

Before we present an overview of different theoretical approaches to social change we need to examine a long-standing controversy in the philosophy of social science.Social scientists have long argued over the degree to which human society and human behavior can be scientifically explained and predicted. At the extremes are two antithetical stances.Some argue that human beings are so smart and societies are so complex that scientific explanation and prediction by means of general laws is impossible. The only thing that can be done from this perspective is to interpret the meaning of particular historical events or conjunctures because meaningful generalization across different situations is impossible.This so-called “idiographic” approach records detailed descriptions of settings or events and tries to understand and evoke the mentalities of the participants.This approach often presumes that efforts to develop a transhistorical species-wide science of human behavior and human societies are doomed to fail and theories that claim to be scientifically universalistic are only sham fig-leaves that are used by the powerful to legitimate their privileges. Extreme historicism, in this meaning, is the position that every village and every human event are unique instances that cannot be meaningfully compared with other instances.

The other extreme position claims that social science is basically like physics. It is possible to discover a set of universal laws that explain human behavior and the nature of all human societies.While nobody claims that this has already been accomplished, the historical trajectory of social science over the past 200 years is seen by ahistoricistsas progress toward the development of“nomothetic,” or law-like, theories of social change.Perhaps the sociological theory that is closestto extreme ahistoricism is the structural functionalism of Talcott Parsons (1966), in which all societies are understood as systems of social actors having the same basic set of functional prerequisites.

In practice there are few social scientists that occupy either of the extreme stances. But many historians are partial to the idiographic stance, while it is usually sociologists,political scientists or anthropologists who are sympathetic to the goals of general explanation.Most practitioners combine the insights of the extreme positions into a stance that contains elements of both, but in this they differ as to emphasis.It is useful to imagine a continuum with idiographic historicism at one end and nomothetic ahistoricism at the other (See Figure 1.2) 

Figure 1.2: Idiographic/Nomothetic Continuum
Few scholars occupy the extremes, but most combine the two approaches in different degrees, and so are at different points on the continuum. It is clear that both stances contain important insights.In sympathy with the idiographic historicists I have already acknowledged that human being are not billiard balls, and that strictly deterministic logic is of little use in social science.For the nomothetic ahistoricists I acknowledge the possibility of an Earth-wide science of social change. 

It is not necessary to assert that all human behavior is equally amenable to scientific explanation. There may be whole sectors of human action that are quite conjunctural and extremely path dependent, in which causality is so complex and interactive that simplifications of the usual sort employed in scientific models are incapable of representing reality.Acknowledging that architectural fashions or literary trends are beyond scientific prediction does not require us to believe that there are no important causal tendencies in the processes of economic and political development.Scholars not only differ with respect to their location on the nomothetic/idiographic continuum, but they also differ with regard to which aspects of social reality they see as more patterned versus those that are understood as primarily conjunctural or unpredictable. 

Theories of Social Change 

Theories of long-term social change differ from one another in two basic ways. One is the extent to which they posit qualitative as opposed to merely quantitative change. And the other is the extent to which they emphasize a single master variable that is allegedly the main cause of change.

Some theories posit a single logic of social change that is thought to adequately describe the important processes in all types of human societies and in all periods of time. Others argue that the logic of social change has itself altered qualitatively, and so that a model that explains, for example, the emergence of horticulture, is not adequate for explaining the emergence of capitalism.Those who see long-run continuities of developmental logic are called “continuationists,” while those who posit the existence of fundamental reorganizations of the logic of social change are called “transformationists.”Continuationists contend that similar processes of social change have operated for millennia, while transformationists see qualitative reorganizations of the processes of change as having occured. The content of the models within each of these categories is quite variable depending on what sorts of social change are seen as most central or powerful – the master variables.

The master variables can be broadly categorized as either cultural or material, but within each of these two boxes there are several significant subtypes.Culturalists often emphasize the importance of the ways in which values are constructed in human societies, and so they focus on religion or the most central institutions that indicate the consensual and most powerful value commitments of a society. From this point of view the most important kind of social change involves redefinition of what is alleged to exist (ontology), and changes in ideas about good and evil.Social evolution is understood by culturalists as the reorganization of socially institutionalized beliefs. For example,the important changes in social evolution are understood to have been the transitions from the animistic philosophy of the hunter-gatherer band to the radical separation of the natural and supernatural realms in early states, and then the rise of the “world religions,” followed by the emergence of formal rationality and science – the dominant “religion” of the modern world.Other social changes are seen by culturalists as down stream from these most fundamental transformations of ideational culture.

Materialists focus primarily on the material problems that all human societies face and the inventions that people employ to solve these problems. They note that humans must eat and that in order for human groups to survive they must provide enough food and shelter to allow babies to be born and to grow up.Thus all human societies face demographic and economic problems, and the ways in which these problems are solved are important determinants of other aspects of social life.Materialists assertthat human societies need to adapt to the natural environment and to the larger social environment in which they compete and cooperate with other human societies.Materialists often differ as to which material problem is seen as most crucial and determinant. Some emphasize demographic and ecological constraints, while others focus on technologies of production or of power.Technologies of production are those techniques and practices by which resources are acquired or produced from the natural environment.Technologies of power are those institutions that create and sustain hierarchies within human societies and that allow some societies to conquer and dominate other societies. 

Institutional Materialism

The theoretical approach employed hereis termed “institutional materialism.” It is a synthetic and flexible combination of culturalist and materialist approaches that sees human social evolution as produced by an interaction among demographic, ecological and economic forces and constraints that is expanded and modified by the institutional inventions that people devise to solve problems and to overcome constraints.Institutional inventions include ideological constructions such as religion as well as technologies of production and power.Technologies of production are such things as bows and arrows, the potter’s wheel and hydroelectric dams. Technologies of power are such things as secret societies, special bodies of armed men, methods of keeping records of who has paid taxes, tithes or tribute, as well as intercontinental ballistic missiles.

Solving problems at one level usually leads to the emergence of new problems, and so the basic constraints are never really overcome, at least so far.Institutional materialism sees a geographical widening of the scale of ecological and social problems created by social evolution rather than a transcendence of material constraints.This is what allows us to construct asingle basic model that represents the major forces that have shaped social evolution over the last twelve millennia.

As mentioned above, institutions are inventions that are made by people for solving problems. Much of the taken for granted aspects of our world are composed of institutions that have been socially constructed by people in the past. Thus we all learn a language when we are children, a particular language with particular meanings and connotations.Our mother-tongues are social constructions of people who spoke and made meaning in the past, including those who raised us and those who taught them. Our particular languages are central institutions that heavily influence our understanding of what exists, what is possible, what is good and what is evil.Other institutions that are historical inventions are money, the family and productive technology. 

Institutions in the sociological sense are more than just hospitals or schools. They are all the socially constructed and taken for granted aspects of everyday life, including who we think we are and what we think exists. The self, in the sense of our idea of our individual identity and what we think human nature is,is an institution in this sense.Institutional materialism analyzes the interactions between the material aspects and necessities of human life and the invention of culturally constructed institutions.

Social structure is the main focus for the study of social change. Individuals are born and die and so all societies are composed of structures in which individuals either reproduce institutions in much the way that they have been in the past, or they alter these institutions. The easiest way of conceptualizing social structure is as an organizational chart in which the various positions that constitute the organization are shown along with their relationships with one another.

Figure 1.3 :Social Structure as an Organizational Chart

All formal organizations and bureaucracies are explicitly conceptualized as constellations of social positions (statuses) in which different individuals occupy the various positions. So a football team has a quarterback, and a halfback and a center and etc. Specific duties are assigned to these positions, and a particular player is evaluated in terms of how well or poorly he or she carries out the duties associated with the position.Sociologists point out that informal as well as formal groups may be viewed as having social structures.A group of friends having lunch may be understood as performing certain scripts appropriate to equals who care about one another, with a degree of improvisation thrown in to constitute genuineness and agency.All social groups are constituted in this way as organizations with rules and assumptions.

This structural view of human society focuses on the rules and definitions that provide the boundaries within which individuals carry out and reproduce social structures.But these structures also change, and the study of social change is, in large part, the effort to explain why structures change in the way that they do.

Social structures are held together by three basic kinds of institutional “glue.”Social order is produced by institutions that make human behavior somewhat predictable.In order to compete, fight or cooperate with others I need to be able to guess what they will do in reaction to what I do.There are three basic institutional inventions that facilitate relatively stable expectations about the behavior of others:

1.normative regulation in which people agree about the proper kinds of behavior,

2.coercive regulation in which institutionalized sanctions are applied to discourage behavior that is considered to be inappropriate;

3.market regulation in which individuals are expected to maximize their returns in competitive buying and selling.

Normative regulation based on consensus about proper behavior is the original institution of social order. It requires a shared language and a good deal of consensus about basic values and proper behavior. Individuals learn the rules and internalize them and regulate themselves and others with appeals to the moral order. This works well in small societies in which people interact with one another frequently and on a relatively egalitarian basis.Itworks less well (by itself) in larger societies that require that culturally different and spatially separated peoples cooperate with one another. 

Coercive institutions (but not coercion) were invented with the rise of social hierarchies.Institutions such as the law do not require that each individual know or agree with the law. Thus they work better for integrating communities that do not share common cultures and moral orders. Legal regulation is backed up by legitimate violence, the right of the lord or the king to enforce the law by means of punishment and prisons. Special bodies of armed men are used to enforce decisions made by states, as well as to engage in conflict with other societies. Courts are part of institutionalization of coercion as an important form of social regulations. 

Market regulation emerged even more recently with the invention of money and commodities. Market regulation, like institutionalized coercion, does have a basis in presumed norms, but these norms themselves only provide the framework for interaction. They do not require agreement about much, except that money is useful.Markets articulate the actions of large numbers of buyers and sellers without requiring these players to identify with one another or even to agree about the general rules of legality.Markets are institutions that allow for relatively peaceful cooperation and competition among peoples that are spread over wide distances and who have rather different cultures.

Much of the sociology of roles, statuses and social structure is based on the assumption that normative regulation is operating, but many social structures operate in the absence of much consensus because they are regulated by coercive or marketinstitutions.The invention of these institutional forms of regulation have made organized social interaction possible on a greater and greater spatial scale until now we have a single global network in which all three kinds of regulation play important parts.The story of how these inventions came about is central focus of the study of social evolution.

The structuralist approach that is an important part of institutional materialism is not, contrary to what some critics have alleged, a necessarily deterministic approach to social life that eliminates the possibility of human freedom. Institutional structuralism allows us to understand the constraints that our own cultures have placed upon us so that, to some degree, we can transcend these constraints.We see socially constructed institutions as human inventions that both empower us and constrain us in certain ways. The fact that the U.S. government has purchased, graded and maintained a piece of property that is 3000 miles long and 200 feet widemakes it possible for me to drive from Baltimore to San Francisco in less than three days, while my ancestors took three months to make the same trip.This is technological and institutional empowerment.But the same Interstate highway system means that the U.S. has invested a huge amount of money, energy, property and human labor into a particular kind of transportation network that might become obsolete due to some future change in technology or in the cost of energy. The canals of Venice or Amsterdam represent sunk costs that could not easily be reconstructed when transportation technology changed.Our religions, the ways in which we have defined male and femaleness, the huge psychic investments in nationalistic sentiments, the expensive rituals by which we demonstrate our commitments to some people and our enmities to others -- all these institutionalized aspects of our society make it possible for us to do some things, and very difficult to do others.This is empowerment and structural alienation.The analysis of institutional structures makes it possible to understand how our history has constructed us and what we may need to do to reconstruct the future.

Institutional materialism is an synthetic and eclectic theoretical focus that draws from several social science disciplines: history, anthropology, sociology, political science, economics, demography and geography. This will be combined with social geography as it has emerged from the comparative world-systems perspective, the main topic of the next chapter.These tools will help us to see the broad patterns as well as the unique aspects of different kinds of societies in the process of social evolution.
