On a recent television interview I was asked how many belief systems I thought there were on this planet. Since every brain is different and beliefs are a brain’s own opinion, then in a sense each brain has its own belief system, which means there are seven billion plus belief systems (give or take a few) on this planet. To put it another way, each brains only has its own opinion. People talk about soft science and hard science, for example, as if hard science, so called, comes from some absolute authority. Human brains planned every research project, analyzed the data, and developed a conclusion. Everything is filtered through someone’s brain . . . Therefore I often preface a statement by saying “My brain’s opinion is . . .” or “In my brain’s opinion,” because I am clear that’s what it is. No matter that it may be based on research or empirical observation and experience, my filters everything as does every other functional brain on the planet. More tomorrow.
