ABSTRACT
However, all possible ideas about the way in which mind and brain are connected have their advocates even if some are less fashionable than others, some on the way up and others going down. It’s the uncertainty and the endless space for theorising that make for unhappiness. One longs, after a time, for a solid stone to kick in the manner of Dr Johnson when he refuted idealism (the philosophy which holds that things don’t exist independently of awareness of them). There are stones, even though they are not that solidly grounded, but they have been herded, to mix metaphors, into the next Chapter. Readers who become sickened by too much theory are welcome to skip on to it, but please pause at the sections on Penrose and on Marshall, as well as at the ‘conclusions’, or an important part of the next Chapter will be unintelligible.
