I have this fixation that our minds, including hearing. sight, taste, smell and vision our not purely the function of biological brain activity. For example, I am sitting here on the couch listening to music on my headphones, and I am convinced that there's no way the grey mushroom-like mush of my brain could produce these sounds in all their complexity, richness and depth. I muse to myself that consciousness and all its contents are beamed from someplace else, and the brain is merely a receiver. Now I know there is a correspondence when parts of the brain are cut out, and this can deteriorate specific functions, but that could be down to certain parts of the receiving apparatus malfunctioning. And no it's not true that science has explained consciousness. Far from it. My notion here is wacky, and I know I'm not the first person to think it - thus the expression "You must be out of your minds!"
