While I spend most of my time studying the realities that affect me most directly, those that drive economies, the markets, and the people I deal with, I also spend time in nature and can’t help reflecting on how it works by observing, reading, and speaking with some of the greatest specialists on the subject. I’ve found it both interesting and valuable to observe which laws we humans have in common with the rest of nature and which differentiate us. Doing that has had a big impact on my approach to life.
First of all, I see how cool it is that the brain’s evolution gave us the ability to reflect on how reality works in this way. Man’s most distinctive quality is our singular ability to look down on reality from a higher perspective and synthesize an understanding of it. While other species operate by following their instincts, man alone can go above himself and look at himself within his circumstances and within time (including before and after his existence). For example, we can ponder the ways that nature’s flying machines, swimming machines, and billions of other machines, from the microscopic to the cosmic, interact with one another to make up a working whole that evolves through time. This is because the evolution of the brain gave man a much more developed neocortex, which gives us the power to think abstractly and logically.
While our higher-level thinking makes us unique among species, it can also make us uniquely confused. Other species have much simpler and more straightforward lives, without any of man’s wrestling with what’s good and what’s bad. In contrast with animals, most people struggle to reconcile their emotions and their instincts (which come from the animal parts of their brains) with their reasoning (which comes from parts of the brain more developed in humans). This struggle causes people to confuse what they want to be true with what actually is true. Let’s look at this dilemma to try to understand how reality works.
When trying to understand anything, economies, markets, the weather, whatever, one can approach the subject with two perspectives: Top down: By trying to find the one code/law that drives them all. For example, in the case of markets, one could study universal laws like supply and demand that affect all economies and markets. In the case of species, one could focus on learning how the genetic code (DNA) works for all species. Bottom up: By studying each specific case and the codes/laws that are true for them, for example, the codes or laws particular to the market for wheat or the DNA sequences that make ducks different from other species.
Seeing things from the top down is the best way to understand ourselves and the laws of reality within the context of overarching universal laws. That’s not to say it’s not worth having a bottom-up perspective. In fact, to understand the world accurately you need both. By taking a bottom-up perspective that looks at each individual case, we can see how it lines up with our theories about the laws that we expect to govern it. When they line up, we’re good.
By looking at nature from the top down, we can see that much of what we call human nature is really animal nature. That’s because the human brain is programmed with millions of years of genetic learning that we share with other species. Because we share common roots and common laws, we and other animals have similar attributes and constraints. For example, the male/female sexual reproduction process, using two eyes to provide depth perception, and many other systems are shared by many species in the animal kingdom. Similarly, our brains have some “animal” parts that are much older in evolutionary terms than humanity is. These laws that we have in common are the most overarching ones. They wouldn’t be apparent to us if we just looked at ourselves.
If you just looked at one species, ducks, for example, to try to understand the universal laws, you’d fail. Similarly, if you just looked at mankind to understand the universal laws, you’d fail. Man is just one of ten million species and just one of the billions of manifestations of the forces that bring together and take apart atoms through time. Yet most people are like ants focused only on themselves and their own anthill; they believe the universe revolves around people and don’t pay attention to the universal laws that are true for all species.
