The grand illusion of life is that our minds have the capacity to understand reality. But human minds didn't evolve to understand reality. We didn't need that capability. A clear view of reality wasn't necessary for our survival. Evolution cares only that you survive long enough to procreate. And that's a low bar. The result is that each of us is, in effect, living in our own little movie that our brain has cooked up for us to explain our experiences
The notion that our minds can fully grasp reality is a misleading concept. According to Scott Adams in "Win Bigly: Persuasion in a World Where Facts Don't Matter," human cognitive abilities evolved primarily for survival, not for understanding the complexities of the world. As a result, we do not have a clear or comprehensive view of reality as it truly is, which is not necessary for our survival or reproduction.
This limitation suggests that each individual perceives the world through a subjective lens, like protagonists in their own movies, crafted by their brains to make sense of their lives. Consequently, the understanding of reality is more about personal interpretation than an objective truth, highlighting the disconnect between human perception and the actual world around us.
