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?"
To build a folly is essentially to do something a second time, something at an inopportune moment. That something is always the memory of something forgotten, about which we can paradoxically say "There it is again."
Follies were misunderstood, purposeless constructions. They were often only small, extravagant gestures in a garden, easily whisking off the imagination to distant lands, a sort of time capsule built to awaken the memory and induce surprise in passers-by. They marked locations, organized secondary paths in a park, or simply predicted the arrival of better times—a demarcation, a sacred spot, a mysterious trail, a hill whose tragic rocky nature begged for a tower, a party, or the arrival of summer.
I have seen autistic children drawing at a terrific speed and I've always thought that my drawings should not be less rapid, because that speed gives them insignificance. In this speed lies their abandonment and it may cause them to be overlooked as mere doodles. However, I understand that they are like that pristine light that appears when they tell you that you have a tumour. In an instant, everything becomes clear and well-defined. All contours are cruelly illuminated as if it was worth taking a final look at the world. At such times, although the lines in the drawings clump into a skein of events that are indecipherable to ordinary mortals, they can be described in detail by the victim one by one. These are moments when weeds regain their nature as plants.
Only now can I understand these drawings as simple moments of clarity.
