The human brain is very poor at knowing things. On the other hand, it is very rich at believing things. What, for example, does your brain believe? I can tell you some of the things that my brain believes.
I believe (but cannot know) that I may well be the happiest man in the world. I believe that the world that I live in is la dolce vita!
Whatever may be objectively true in physics in the Milky Way, and beyond, as far as my brain is concerned (as far as the cognitive physics of my subjective neurosphere is concerned) my brain has created for me the good life!
We could just stop here. Or, we can go on …
As proof of my brain’s happy belief I have quite a lot of evidence to support it. But, not enough to prove it beyond a reasonable doubt.
What evidence do you have to support what your brain believes?
I must say that although my brain is by no means perfect (far from it!), I’m very pleased with its performance over the last 7 decades. It operates and maintains me. It makes me laugh. It makes me cry. It surprises me and puzzles me. It challenges and also enables me. It plays me. It can ignore me. Trick me. Expose me. Even, hate me. But, to be fair, it has even saved my life on more than one occasion.
I don’t have a pet cat. I have a pet brain. It’s always been the favourite of all my gadgets. I will even go so far as to say, for the first time in public. I love my brain!
