Carl Einstein, Daniel-Henry Kahnweiler, Cubism, and the Visual Brain
On this question Einstein and Kahnweiler held diametrically opposed positions. Moreover–and this is my main interest–their respective positions correspond to successive phases in the developing neuroscientific understanding of the visual brain. Kahnweiler’s interpretation of cubism was shaped by the neuroscience of his day while, remarkably, Einstein’s account of seeing, as he believed it to be embodied in cubist paintings, anticipates by half a century a fundamental breakthrough in the neuroscientific understanding of vision.
