“Our brains are meaning machines. What we understand as “meaning” is generated by the associations our brain makes between two or more experiences. We press a button, then we see a light go on; we assume the button caused the light to go on. This, at its core, is the basis of meaning. Button, light; light, button. We see a chair. We note that it’s gray. Our brain then draws the association between the color (gray) and the object (chair) and forms meaning: “The chair is gray.”
Our minds are constantly whirring, generating more and more associations to help us understand and control the environment around us. Everything about our experiences, both external and internal, generates new associations and connections within our minds. Everything from the words on this page, to the grammatical concepts you use to decipher them, to the dirty thoughts your mind wanders into when my writing becomes boring or repetitive—each of these thoughts, impulses, and perceptions is composed of thousands upon thousands of neural connections, firing in conjunction, alighting your mind in a blaze of knowledge and understanding. But there are two problems. First, the brain is imperfect. We mistake things we see and hear. We forget things or misinterpret events quite easily.
Second, once we create meaning for ourselves, our brains are designed to hold on to that meaning. We are biased toward the meaning our mind has made, and we don’t want to let go of it. Even if we see evidence that contradicts the meaning we created, we often ignore it and keep on believing anyway.”
