Modern neuroscience has come to realise a curious thing. It has noticed that the complex human nervous system creates an artificial reality in the human mind, the correctness of which the speaker, Anil Seth, a British professor of Cognitive and Computational Neuroscience at the University of Sussex, here rightly questions. The reality experienced by human is as much a hallucination as that made by so-called hallucinogens. Anil Seth explains this here as his own view, which I fully accept. Indeed, it is a question of consciousness which do NOT present our environment correctly, but in the way that is most optimal for human survival. I would add here just a small detail: this distortion of reality is meant for the child and the growing individual, but not for the adult. As soon as science accepts the fact that the adult psyche does not function properly, this mystery of consciousness becomes clear.
