“The whole is greater than the sum of its parts”
The study of gestalt originated in Germany in the 1920s. It is a form of psychology that is interested in higher order cognitive processes relative to behaviorism. The aspects of gestalt theory that are of interest to artists are related to gestalt’s investigations of visual perception, principally the relationship between the parts and the whole of visual experience.
The visual world is so complex that the mind has developed strategies for coping with the confusion. The mind tries to find the simplest solution to a problem. One of the ways it does this is to form groups of items that have certain characteristics in common. In short, the whole is greater than the sum of its parts.
