    Don’t fall for the three-brain theory

    It’s an age-old idea that goes back to the days of Plato. That our minds are battlegrounds between three inner forces – basic instincts, emotions, and rational thought. The theory goes that the first force, basic instincts, is the oldest aspect of our brains. The so-called lizard brain. Then came emotions, and, over time, rational thought, which is seen as the higher-evolved force that can keep the unruly animals of instincts and emotions in check.

    But this idea of the brain being segmented like geological layers is outdated. Evolution doesn't stack layers upon the brain; it reshapes and reorganizes it. As our brains grew larger, their organization changed to manage more intricate bodies, signifying that complexity isn't about adding, but about reconfiguring.

    But why do vertebrate brains, developing in similar sequences, end up looking so distinct? The biological building blocks remain consistent across species; it's the timing that changes. Each stage of brain development lasts differently across species. For instance, the stage building neurons for the cerebral cortex is longer in humans compared to rodents or lizards. And it's not just about size either, but also about how these stages are orchestrated in developmental time.

    Although the triune brain theory – that we've evolved three distinct brains over time – has been enticing throughout history, it's more of a self-congratulatory tale. It suggests that by mastering rational thought, humans overcame their primal nature and now dominate Earth. But in reality, even a so-called “false-alarm” response in a high-threat environment could be seen as rational, as it prioritizes long-term survival.

    Ultimately, let’s debunk the concept of having three separate brains right here.  And let’s agree that we possess one dynamic, integrated brain instead. To truly grasp human nature, it's essential to revise our understanding of rationality, responsibility, and even our very essence as humans.
