“Nothing in a portrait is a matter of indifference”*…

 

This unique self-portrait, also known as “view from the left eye”, is the creation of Austrian physicist and philosopher Ernst Mach, noted for his contributions to physics such as the Mach number (which relates an object’s speed to the speed of sound) and the study of shock waves. The sketch appears in Mach’s The Analysis of Sensations, first published in German in 1886 as Beiträge zur Analyse der Empfindungen, and is used to illustrate his ideas about self-perception.

The considerations just advanced, expressed as they have been in an abstract form, will gain in strength and vividness if we consider the concrete facts from which they flow. Thus, I lie upon my sofa. If I close my right eye, the picture represented in the accompanying cut is presented to my left eye. In a frame formed by the ridge of my eyebrow, by my nose, and by my moustache, appears a part of my body, so far as visible, with its environment. My body differs from other human bodies beyond the fact that every intense motor idea is immediately expressed by a movement of it, and that, if it is touched, more striking changes are determined than if other bodies are touched by the circumstance, that it is only seen piecemeal, and, especially, is seen without a head. If I observe an element A within my field of vision, and investigate its connexion with another element B within the same field, I step out of the domain of physics into that of physiology or psychology, provided B, to use the apposite expression of a friend of mine made upon seeing this drawing, passes through my skin. Reflexions like that for the field of vision may be made with regard to the province of touch and the perceptual domains of the other senses…

As we study ourselves studying ourselves, we might send ingenious birthday greetings to a man whose work gave Mach’s namesake speed measure a real workout: Clarence Leonard “Kelly” Johnson; he was born on this date in 1910.  A storied aeronautical engineer, He contributed to the design of 40 aircraft, from the P-38 Lightning fighter and the Hudson bomber to the U-2 spy plane and the F-104 Starfighter interceptor.

But Johnson is probably best remembered as the founding leader of Lockheed’s Skunk Works, a development group that has become a model in the business, engineering, and technical arenas of an effective approach to innovation– a group with a high degree of autonomy within an organization, unhampered by bureaucracy, tasked with working on advanced or secret projects.

“An uninspiring canvas becomes a glamorous masterpiece when it is reattributed to a better-known artist”*…

 

Cornell psychologist James Cutting wondered why it is that when a work of art is considered “great,” we too often stop thinking about it for ourselves…

The intuitive answer is that some works of art are just great: of intrinsically superior quality. The paintings that win prime spots in galleries, get taught in classes and reproduced in books are the ones that have proved their artistic value over time. If you can’t see they’re superior, that’s your problem. It’s an intimidatingly neat explanation. But some social scientists have been asking awkward questions of it, raising the possibility that artistic canons are little more than fossilised historical accidents.

Cutting wondered if a psychological mechanism known as the “mere-exposure effect” played a role in deciding which paintings rise to the top of the cultural league. In a seminal 1968 experiment, people were shown a series of abstract shapes in rapid succession. Some shapes were repeated, but because they came and went so fast, the subjects didn’t notice. When asked which of these random shapes they found most pleasing, they chose ones that, unbeknown to them, had come around more than once. Even unconscious familiarity bred affection.

Back at Cornell, Cutting designed an experiment to test his hunch. Over a lecture course he regularly showed undergraduates works of impressionism for two seconds at a time. Some of the paintings were canonical, included in art-history books. Others were lesser known but of comparable quality. These were exposed four times as often. Afterwards, the students preferred them to the canonical works, while a control group of students liked the canonical ones best. Cutting’s students had grown to like those paintings more simply because they had seen them more.

Cutting believes his experiment offers a clue as to how canons are formed. He points out that the most reproduced works of impressionism today tend to have been bought by five or six wealthy and influential collectors in the late 19th century. The preferences of these men bestowed prestige on certain works, which made the works more likely to be hung in galleries and printed in anthologies. The kudos cascaded down the years, gaining momentum from mere exposure as it did so. The more people were exposed to, say, “Bal du Moulin de la Galette”, the more they liked it, and the more they liked it, the more it appeared in books, on posters and in big exhibitions. Meanwhile, academics and critics created sophisticated justifications for its pre-eminence. After all, it’s not just the masses who tend to rate what they see more often more highly. As contemporary artists like Warhol and Damien Hirst have grasped, critical acclaim is deeply entwined with publicity. “Scholars”, Cutting argues, “are no different from the public in the effects of mere exposure”…

As we cathect on connoisseurship, we might send fantastic birthday greetings to Roger Zelazny; he was born on this date in 1937.  Probably best known for his Amber series, Zelazny was a prominent member– with Philip K. Dick, Samuel Delany, Thomas Disch, Ursula K. LeGuin, and Harlan Ellison– of the American “new wave” science fiction movement; he won three Nebula awards and six Hugo awards.  In 1976, Zelazny helped Philip K. Dick, who wasn’t able to continue on his own, finish Deus Irae; having learned in the process of Dick’s financial straits, Zelazny voluntarily reduced his royalty from one-half to one third.
