Life without Free Will
Determined by Robert M. Sapolsky explores the science of human behavior, emphasizing the biological, genetic, and environmental factors that drive our actions. Sapolsky offers insights into the deterministic nature of our behavior and decision-making.
If you’re anything like most people, you probably wouldn’t be too happy to hear that every decision you’ve made and action you’ve taken, from choosing a life partner to sneaking the last doughnut, has absolutely nothing to do with your own free will and absolutely everything to do with a complex set of biological and cultural cues which are completely outside your control.
So, let’s start on a lighter note, shall we?
Sometime around the turn of the twentieth century, the famous philosopher and psychologist William James was giving a lecture on the nature of the universe. One attendee, an elderly woman, approached him after the lecture to tell him he’d gravely misunderstood the whole thing. The world, she informed him, was balanced on the back of a giant turtle. Bemused, James asked what the turtle was balancing on. “Another turtle,” responded the woman. Well, what was that turtle balancing on? Exasperated, the woman replied, “Don’t you see? It’s turtles all the way down!”
It sounds preposterous, right? And yet there’s a logic to it. Because, preposterous as it is to believe that the world is balancing on a sequence of turtles, it’s even more preposterous to believe that at some point that sequence of turtles just stops, leaving one turtle floating in mid-air. If you accept that the world is balanced on a giant turtle, you also need to accept that those turtles continue downward forever.
So, back to our central argument that everything, including all human action, is governed by factors outside of our individual control – an argument which in a scientific context is referred to as determinism.
Basically, when you behave a certain way, it’s because your brain generates that behavior. And why, you might then ask, does your brain generate that specific behavior and not a different one? Well, it's because the neurons in your brain acted a certain way seconds before the behavior in question. Which they did so because of a thought, emotion, or stimulus stored in your brain. Which was stored to begin with, because of the way your hormones shaped that stimulus, along with how sensitive your brain should become to it. Which they did so because of formative experiences at times when your brain was in different phases of development, like adolescence, childhood, and even in utero. All of which, in part, are a result of your genetic inheritance and to the cultural influences of the society you were born into, which is itself shaped by the ecological and evolutionary pressures that created culture in the first place…
In other words, it’s turtles all the way down.
You might think it’s silly to say that the world balances on the back of a series of turtles which extend infinitely downward. But it’s even sillier to suggest that, at some point, the turtles just stop and some other support system randomly comes into play.
Think about it – you probably accept some iterations of deterministic theory. For example, you probably accept that things like learning disabilities and clinical depression occur because of a mixture of brain function and genetic predisposition. You probably accept that no one chooses whether they’re left-handed or right-handed. You probably accept that people who are abused and neglected as children may grow up to be abusive and neglectful themselves.
Essentially, there are scenarios in which you’re prepared to concede that free will doesn’t come into play. How can you – or more accurately “we,” as the belief in the existence of free will is close to universal across all groups and cultures – accept that some behavior is biologically determined, but not accept that all behavior is biologically determined?
The next few sections will argue that free will doesn’t really, in any meaningful sense, exist; what’s more, they’ll show why accepting this proposition might actually be a good thing.
Determined (2023) argues that free will is an illusion – all human behavior stems from biological and cultural factors we don't control. Through scientific research and case studies, it lays out the argument in favor of determinism, and aims to persuade why rejecting the notion of free will might be a positive step.
Determined (2018) by Robert M. Sapolsky is an insightful exploration of the biological and environmental factors that contribute to human behavior, offering readers a deeper understanding of what drives us. Here's why this book is worth reading:
It's highly addictive to get core insights on personally relevant topics without repetition or triviality. Added to that the apps ability to suggest kindred interests opens up a foundation of knowledge.
Great app. Good selection of book summaries you can read or listen to while commuting. Instead of scrolling through your social media news feed, this is a much better way to spend your spare time in my opinion.
Life changing. The concept of being able to grasp a book's main point in such a short time truly opens multiple opportunities to grow every area of your life at a faster rate.
Great app. Addicting. Perfect for wait times, morning coffee, evening before bed. Extremely well written, thorough, easy to use.
