James J. Gibson — American Psychologist born on January 27, 1904, died on December 11, 1979

James Jerome Gibson, was an American psychologist who received his Ph.D. from Princeton University's Department of Psychology, and is considered one of the most important 20th century psychologists in the field of visual perception. Gibson challenged the idea that the nervous system actively constructs conscious visual perception, and instead promoted ecological psychology, in which the mind directly perceives environmental stimuli without additional cognitive construction or processing. A Review of General Psychology survey, published in 2002, ranked Gibson as the 88th most cited psychologist of the 20th century, tied with John Garcia, David Rumelhart, Louis Leon Thurstone, Margaret Floy Washburn, and Robert S. Woodworth... (wikipedia)

Psychology is still trying to explain the perception of the position of an object in space, along with its shape, size, and so on, and to understand the sensations of color.
The meaning or value of a thing consists of what it affords.
Hence it is that the shape of something is especially meaningful.
The abstract analysis of the world by mathematics and physics rests on the concepts of space and time.
I also assume that they are not simply the physical properties of things as now conceived by physical science. Instead, they are ecological, in the sense that they are properties of the environment relative to an animal.
