There are times when we become angry and attack another person with violent words, and although our heart is racing, our breathing is labored, and our body is becoming exhausted from the effort, we just can’t seem to stop. Because the data we’re receiving are being converted from being a pleasure, we delude ourselves that we’re experiencing pleasure when we suffer. Because of that, we get angry and jealous, which should make us uncomfortable, but we just can’t seem to stop. There’s an evolutionary aspect to this. For example, take the brains with animals like earthworms and leeches. They’re more primitive than mammals’ brain, consisting of bundles of nerves and ganglions, which is similar to the brain, all over their bodies. When we think about how the brain has evolved in these animals, we can imagine it may have developed as an efficiency feedback system. Information from external sources reach the ganglions, conveying sensations of touch, smell and light. These then decide whether the animal should flee, make an approach or remain still, providing feedback to the part of the body that initiates physical movement. That’s the process of evolution as evolution criteria for determining whether to convert input to output, I think the initial values that the brain is equipped with our pain and discomfort.
