With well over 300 positive reviews from various sources, Wright’s book can easily be summarized as a very important contribution to a detailed yet encompassing understanding of biological and cultural evolution’s contribution to the human condition through time. Lots of time, leading to his focus on the present and future.
The extensive reviews do an excellent job of relating all his major points, and the reviewer’s personal reaction to them—which always must be kept in sight and also provide a glimpse into the thinking which Wright touches upon at various points in his book. So, there is no need for me to go there. I really enjoyed the cultural and historical details of support for his overall perspective in particular, and his playful narrative using down-to-earth examples and comments. Where I do want to go is to that overall perspective which I consider essential to understanding human decision-making: game theory.
There are four outcomes possible: 1), zero-sum (I win or lose) in a contention of action or 2), non-zero-sum (I and my opposite either both lose or both win) in a contention of action. Now, as Wright points out in his detailed examples throughout the book, although the zero-sum result can be really bad for the loser all the way up to not so bad, it’s still losing. Likewise with a non-zero-sum result, it can be a great positive result for both all the way to a really bad result for both. History is basically a recorded narration of the degrees of zero-sum and non-zero-sumness that has resulted from all the contentions of action that have occurred through recorded time, including non-recorded evidence as a result of scientific inquiry, such as biological and archeological evidence. Given this lens, a fundamental understanding of how stuff happens is greatly clarified—the rest is interesting detail about the characters, cultural concepts and associated behavior, geographical characteristics, and timing of how it all took place.
And Wright would add that it’s not just interesting, and entertaining at times, but also shows a tendency over time to be more and more complex. Not always, because many times positive nonzero action should have been taken but instead came out with a negative result (because those invading hordes really did have super iron swords, or that volcano really did erupt despite warnings from nearby traditional enemies). But overall, decisions about contentious situations tend to be positive nonzero and that is the driving force, or “destiny,” of humanity: to just do better next time overall. It simply adds up over time, because it lays the ground for it to happen a little more frequently despite some setbacks.
Unfortunately, many reviewers get lost in the trees and forget the encompassing forest I just described, especially with the end of the book. Some say it’s too optimistic, and others want something more positive. Well, Wright gives both: We can do better, just work more cooperatively for positive nonzero-sumness, but things can also go very wrong when we don’t and humanity will experience a setback. However, overall the trend over time—lots of time—is more positive nonzero and resulting complexity. That’s all he’s saying, and hoping we all make the right choice. That definition of “destiny” I can live with.
Now, if I can take a moment for a bit of extended discussion, there seems to be one element that is missing in this scenario presented by Wright, and I should add, probably by all such analyses of decision-making. And that is motivation for making decisions. Why do humans end up in situations where they have to make decisions, or are simply motivated by their body to take any action, such as by their autonomic nervous system, which forces that person to take some action—not just consciously via their brain but continuously millions of times a day automatically by the cells which constitute the body whole? Why not just remain in a condition of stasis until . . . what, something happens?
That’s the key: something happens, and the body has to react or, ultimately, die. This could be a threat from an element of nature such as a rainstorm, temperature change from weather, a rock falling down towards you because of gravity, or other similar threats. That would get you moving, but again, the question is why? Well, because your body might be uncomfortable or even die. That would be motivation to action, but what is it that the motivation is for, ultimately? Most simply put, the motivation is to control one’s environment, to avoid being too hot or cold or having a rock falling on your head. That fact, control, is the motivation for you to make a conscious decision or an automatic one by your bodily cells to get moving and save yourself.
That’s pretty simple when dealing with situations caused by inanimate forces or objects. Ah, but what happens when the conflict occurs with animate objects, other life forms? Then is when Wright’s use of game theory comes into play, as his book amply illustrates, because the source of motivation is now other living beings who are also seeking their own best interest, just as you are: whether it be a crouching lion, nourishing plant, disease producing bacteria, or that woman or man soliciting you to contribute time or funds for their social cause.
So, is the decision for action to be carried out in a zero-sum or a nonzero format, and what are the expectations and chances involved? Again, Wright provides extensive examples of how humans have made those decisions and played the game throughout history and face such decisions for the future. The necessity for each person—and by extension for every living being, bacteria, plant, or animal—to try to control as much of their environment as possible is the key to defining the difference between animate and inanimate elements on Earth and elsewhere in the universe, for that matter.
By the very nature of the first constituting chemical reactions which gave form to reproducing and growing cellular structures, control was necessary. And the scene was set through genetic material and evolutionary processes for increasing the potential to survive control situations and thereby the general direction of complexity, as is amply described by Wright. It is the need for control and survival which therefore motivated all life forms to continually improve their faculties for control, first based solely on genetic-derived enhancement but later through learning and memory via increasingly complex neurology and later through culture, possessed primarily by humans, which allowed the transmission of that learning to more efficiently control their environment—and play the zero-sum and nonzero-sum games with more complexity.
It seems to me that this is the missing link, control as motivation, for explaining why we engaged in game theory decisions in the first place, starting those millions of years ago, and why we still do so today: because we have to. We must attempt to control our lives as much as possible, and the way for us humans to do that is primarily by the only choices we have: win or lose, or take the next step and try to cooperate. That’s how Wright’s splendid conceptual framework fits in this game of Life.
