This is a pretty cool repository of really interesting ideas and opinions, with a non-business model (no ads, paid writers, no obvious way of “donating”). I have only read the article on “The empty brain” which has some challenging ideas although also has certain unanswered challenges too. It has a nice little interview with Brenda Milner and heaps of other things.
