I will point out that "Structuralism" is critical in modern mathematics [which is very abstract, its greatest champion being Alexander Grothedieck], and even art.
"Experiments have shown that, by changes in electrical fields, the brain prepares actions before we become conscious of them. It takes from a half to a second and a half of cerebral activity (evoked response and Bereitschaftspotenzial and other fancy phenomena) to become conscious of what is going on âback thereâ."
Who is taking all the decisions? Our higher self some think.
