Abstract

‘There just has to be some connection between thinking and what goes on in my head when I am thinking,’ said someone to me recently. ‘When I am thinking,’ he continued, ‘the thinking is going on in here’, at which he pointed with his forefinger at his head. I indicated mild dissent. ‘You seem to me to be overlooking plain facts,’ he retorted. ‘There are thoughts in my head. Nothing could make me doubt that. If I am given a complicated calculation to do, I might start off by trying to do it in my head but, finding it too hard, I might continue the calculation I had begun in my head on paper, on the table in front of me . The calculation started off being done in my head and finished up being done on paper.’.
