Which half? One day when I was a junior medical student, a very important Boston surgeon visited the school and delivered a great treatise on a large number of patients who had undergone successful operations for vascular reconstruction. At the end of the lecture, a young student at the back of the room timidly asked, "Do you have any controls?" Well the great surgeon drew himself up to his full height, hit the desk, and said, "Do you mean did I not operate on half of the patients?" The hall grew very quiet then. The voice at the back of the room hesitantly replied, "Yes, that's what I had in mind." Then the visitor's fist really came down as he thundered, "Of course not. That would have doomed half of them to their death!" God, it was quiet then, and one could scarcely hear the small voice ask, "Which half?" E.E. Peacock Jr., Seeing With Fresh Eyes science
No reason for being "A lot of what I had been doing in those large gestural paintings seemed to me afterwards as being not very controlled, in the sense that a lot of stuff that was going on in them had no reason for being there. There were just too many things that were accidental, too much incidental, too many contradictions." Lawrence Wechler & Robert Irwin, Seeing Is Forgetting the Name of the Thing One Sees Controlled!
