People have a natural tendency to seek agency. If something momentous happens, then someone must have caused it. If something complex exists, someone obviously designed and built it. But this natural human way of looking at things leads to unwarranted assumptions. No one, for example, planned the evolution of life.
Ridley extends Darwin’s insight about biological evolution to human culture and invention. No one planned the development of language. No one planned the industrial revolution. No one planned today’s global economy. These things evolved. They weren’t designed from the top down. They emerged from the bottom up. In this book, Ridley specifically argues that Adam Smith’s Invisible Hand guides economics in much the same way that natural selection guides the evolution of life. Both emerge from the complex interplay of individual agents acting out of self-interest with no common goal. They operate without any grand plan, and yet they create (albeit unintentionally) complex, well-ordered, and reasonably efficient systems. He has great faith in the power of the Invisible Hand. Don’t try to direct it, and good things will happen.
To me, his belief in the power of the Invisible Hand seems a bit too…well, utopian. Simplistic. Possibly even a bit mystical. The Hand works in mysterious ways. We don’t know how, exactly, but we must have faith that it is all for the best and let it get on with things. As long as we don’t interfere, all will be well. Society will evolve for the better. The state will wither away, and everyone will live in peace and prosperity. His end state seems ironically similar to the one Karl Marx envisioned, and I think it’s flawed for one of the same reasons Marx’s was—people. They aren’t ready for it…yet. There are those, and I like to believe the number grows with every generation, who do not require coercion or the threat of divine or secular punishment in order to behave properly toward their fellow human beings. But many still do. The state may be an unfortunate necessity at this point in human evolution.
If it’s possible to be a cynical optimist, Matt Ridley qualifies. He makes several valid points in this book. Order can emerge from chaos. Actions motivated solely by self-interest can have unintended and broadly beneficial consequences. Human culture does evolve, and it has progressed and improved over time. But he makes an unjustified leap by concluding that it is therefore a mistake to attempt to bring about cultural change or broad social benefits intentionally. Evolution, both biological and cultural, he seems to argue, are best left to natural selection and the free market. Restraining the Invisible Hand leads to disaster.
Well, it can, except sometimes it doesn’t. Sometimes the Hand needs a shove. Or maybe it’s better to say that the Invisible Hand has more fingers than he seems to think it has.
Ridley often sounds like a cranky old man grinding philosophical axes*, and in this book, he vents his libertarian spleen on all things that smack of authority. This includes religion and crony capitalism, but his favorite target is government in all its current and historical forms. He doesn’t like government (which seems odd considering that Viscount Ridley is a member of the British House of Lords). He sees it as a top-down intrusion on the proper bottom-up evolution of human society. Let the free market work!
But there is no free market, and I doubt one would last long if there was. (See Saving Capitalism by Robert B. Reich https://www.goodreads.com/book/show/24338377-saving-capitalism) Markets in our modern society depend on governments to protect capital assets and intellectual property. Governments provide the framework within which individuals and businesses negotiate contracts with one another, and they provide legal recourse in the event of contract violation. Governments maintain competition by restricting monopolies so that large corporations cannot eliminate their existing and potential competitors (e.g. through hostile takeovers, dumping goods, or intimidating suppliers). Governments also help bolster the economy by instilling consumer confidence. Because of governmental regulations, you can be fairly sure that the food and medicine you buy isn’t toxic; that your appliances, cars, homes, and other purchases are reasonably safe to use; and that whatever else you buy will function almost as well as the seller claims it will. If you are in the unfortunate position of having to work for a living, your workplace is probably safer, your workday shorter, your pay better, and you may even enjoy some kind of insurance or even paid holidays because of governmental policies.
A firm believer in laissez faire economics might argue that all of these benefits would come about on their own accord through the magic of market forces, but they didn’t, which is why these governmental policies came about. Worker exploitation, sweatshops, child labor, and unsafe working conditions were rampant only a century ago. The case of the Triangle Shirtwaist factory fire in New York City in 1911 is probably one of the most famous examples. (http://www.history.com/topics/triangle-shirtwaist-fire). In a bottom-up effort, voters demanded that something be done. Government responded by enacting laws. (e.g. the U.S., the Federal Trade Commission Act of 1914, the Fair Labor Standards Act of 1937, the Occupational Safety and Health Act of 1970, the Consumer Product Safety Act of 1972). Admittedly, these probably did not all work as well as many hoped, and some may have had unforeseen consequences, but these laws and others were passed because the ‘free’ market had not been able to prevent abuses by private businesses that exploited workers and cheated consumers. Clearly, not all business were dishonest or exploitative, but a top-down mandate was needed, not only to protect workers and consumers, but also to establish a level playing field to protect responsible business owners from unfair competition by those who were not.
So, were these societal changes examples of bottom-up evolution brought about by voter demand or were they top-down impositions on the free market by government? Both? Neither?
Personally, I think it’s a false dichotomy. Let me begin by saying that power bases emerge in human society whether you want them to or not. They form from the bottom up. We can’t prevent them, nor do I think we should try. They exist to pursue the interests of their constituents, and in doing so can provide benefits to each member that they cannot obtain as well on their own. But they can also unjustly impose their will on nonmembers. If one group becomes too powerful, or if two or more combine forces, they can oppress or exploit others. Maintaining some kind of power balance so that this does not happen can be difficult.
Prior to the Enlightenment, government, in the form of a monarch and sundry aristocracy, could be seen as a separate power base, as could the Church, landed gentry, craftsmen, and peasants. Each of these had its own unique interests, which they pursued, sometimes cooperatively but often competitively. If you wish to imagine society as something guided by an invisible hand, these would have been its fingers, the two strongest of which were the monarch and the Church.
Modern Western society has different fingers. These can be generalized as workers, consumers, business owners, and bankers. Religion is still with us, of course, and it does have unique interests and it does exert power, so it may be seen as a finger as well. As in the past, these groups may have overlapping constituencies, but they don’t have common goals, and the conflicts between them create the evolutionary pressures that move societies. Together, these five fingers shape human culture in unplanned ways. (I don’t include government as one of these modern fingers for reasons I’ll explain soon.)
All of these fingers represent their members and push society in some way. Consumers want quality products at affordable prices. Workers want secure, well-paying jobs. Religions want to spread their faiths. Businesses and banks want to earn profits for owners/investors. Democratic government is a bit different in that it represents (or should represent) interests common to everyone. As difficult as it may be to imagine at times, and despite the real differences that may exist between them, all people have more interests in common than not…safety, property, opportunity, freedom…or as the U.S. Declaration of Independence puts it, life, liberty, and the pursuit of happiness.
A properly functioning democratic government has the unenviable task of ensuring equal rights for all its citizens and for being an impartial arbiter when the goals of the metaphorical fingers come into conflict. Is it more important for consumers to have lower prices or for workers to have higher wages? Are these more or less important than business owners reaping high profits or banks charging high interest? When does a religion’s goal of spreading the faith intrude on the freedom of nonbelievers? These are not hypothetical questions. All have had to be addressed in the past, and it has fallen on governments to do so because market forces can’t, at least not as well. When one group attempts to dominate, exploit, suppress, or even eliminate another, the purely evolutionary solution of allowing the strongest to win is probably not the best one for the long-term survival of a civilization. The government stands in defense of all, regardless of numbers or wealth. It codifies protected rights that apply to all its citizens, and it acts as a societal ratchet to prevent these rights from being denied in the future. Once proscribed by law, such things as slavery, child labor, and racial discrimination are far less likely to reemerge. A democratic government provides a balancing force so that the many cannot dominate the few and the rich and powerful cannot prey on the poor and weak.
The balance breaks down if one societal power base exerts too much influence over governmental policies. Business control of government is just as detrimental to a society as governmental control of business. But democratic governments are self-correcting. They change from the bottom up. The dominating powers will fight to preserve their privileged positions. They’ll try to bend public opinion to maintain their position, but when voters feel that one group has too much influence, they’ll vote for change…and they might even achieve it. We may be seeing something like that happening now in the U.S. Time will tell.
There is much about Matt Ridley’s argument with which I do not agree, but his central point that complex systems evolve in unexpected and unplanned ways is undeniable. They do. No single strategy directed the course of human progress. The scientific discoveries and cultural changes humanity has made since our ancestors first chipped stones into knives two and a half million years ago (or thereabout) have created a world that no one could have imagined, let alone planned. These advancements emerged incrementally, iteratively, one thing leading to another, with all the parts interacting in complex and often unpredictable ways. In short, our society evolved. There was no grand plan, but many of the little steps along the way were planned, which is where the comparison of scientific and cultural progress with biological evolution breaks down. The two processes appear similar from a great enough distance, but they differ in the details.
Biological evolution lacks intent. Cells and microbes can’t imagine the future. They can’t plan. Over time, the individual cells that comprised the earliest forms of life came together, differentiated, and specialized to form larger and more complex organisms. This improved their survivability, but they didn’t adapt to survive. They survived because they adapted. This is an important difference. It’s a matter of cause and effect. It took natural selection billions of years to go from those earliest microbes to creatures like us because it operates without intent. It doesn’t build to a plan. Discrete biological changes (to DNA) are close enough to random to think of them as such, and most of those random mutations are fatal. Natural selection can create astounding complexity in this manner, but it’s hit or miss, and it takes a while.
Cultural evolution is faster. The time span from Homo erectus to Homo sapiens took almost two million years. The time span from steam engines to nuclear power was less than three hundred. Why? Well, a lot of reasons, but complexity isn’t one of them. There are more differences between Newcomen’s steam engine and a nuclear reactor than there are between you and your multi-great grandmother a couple million years ago. A big factor for the difference in time scale is that each evolutionary step from pre-modern humans to us relied on unplanned natural selection. Each development between steam power and nuclear energy was the result of human premeditated action. Each improvement, every new idea along the way was proposed and developed by a human mind with intent.
Ridley summarizes his position in the epilogue of his book. “To put my explanation in its boldest and most surprising form: bad news in manmade, top-down, purposed stuff, imposed on history. Good news is accidental, unplanned, emergent stuff that gradually evolves.”
Ah, if only reality were that simple. The unfortunate truth is that most evolutionary changes are failures. Unplanned evolution doesn’t always bring success but neither does planned change. Most plans people make fail as well. What Ridley’s argument seems to boil down to is that evolutionary changes that have survived are successful. True, but tautological. Extrapolating from this dubious insight by claiming that unplanned evolutionary change is good and that manmade change is bad is simply absurd. It’s like claiming that doctors shouldn’t cut out tumors, prescribe antibiotics, provide vaccinations, or attempt to cure genetically inherited diseases because the bacteria, viruses, and genetic mutations they are trying to eliminate have evolved through natural selection and therefore must be good.
Let me offer an alternate idea. Human culture and technology have advanced rapidly because when people see problems, they take action to fix them. They don’t wait around for the slow plod of evolution to make things better or, alternately and more likely, to drive them to extinction. Humans are toolmakers. The things we create, from hammers to stock markets, are tools that we intentionally design to accomplish certain tasks, and we improve upon them over time to make them work better.
By all measurable criteria, our species’ quality of life has improved over time. People today (on average) are healthier, eat better, live longer, are freer, safer, and enjoy more material wealth than at any time in history. No one planned the current state of human affairs. It isn’t anyone’s imagined end state or ultimate goal. There is no end state. There is no final goal. Evolution is a continuing process. The reason our cultures evolve faster than our biology is partly that they have something biology does not. When it comes to the components of human culture, such as our religions, laws, forms of government, economic systems, philosophies, ethics, educational systems, music, art, inventions, and all other creations of the human mind, an intrinsic part of all of them is that they include an element of intent. People designed them from the top down in response to conditions imposed from the bottom up. They saw situations that they wanted improved, considered ways of adapting what they knew to the problems facing them, and came up with ideas they thought might work. Some did. Some didn’t. Those that work are more likely to survive. Richard Dawkins calls such ideas memes, but the important point is that these ideas do not spring up spontaneously. They originate in human minds. And although each of these ideas may be intended to address separate, seemingly unconnected issues, each forms a small component of a larger evolving system. Unlike biological evolution, human progress has an aspect of intelligent design.
Which brings me back to Ridley’s issue with government and the free market. The Invisible Hand of the free market is not a separate ineffable force any more than the human mind is separate from the brain and body that create it. Both can be seen as emergent properties. But perhaps a better way to view the free market for this discussion is as a process. Just as evolution describes the process of living matter reacting to its environment, the free market describes the process of humans interacting to improve their lives. To do this, they build tools. If those tools don’t work quite as well as we’d like, we try to improve them.
Businesses are tools. Banks are tools. Government is a tool. All of these are designed, built, modified, and used by people in order to improve their lives, and, over time and not at all miraculously, our lives have improved. Since this was and is the common intent, I’d say we’re not doing too badly. Evolution gave us our toolmaking ability. It would be a shame not to use it.
*So am I, but that’s beside the point.
