From Ronald Wong
It was interesting to read great scientific minds like Roger Penrose grappling with the apparent paradox of reality (18 November, p 32). We artists, at least those of a realist/representational bent, have had to confront these issues of virtual versus objective reality in our own way: pick up any good book on visual perspective, and you will have there the rudiments of the conscious field and its mathematical relationship with reality. Maybe the views of artists are beyond your brief here, but once upon a time, back in the Renaissance, we were all in the same boat.
