Duelling Hemispheres of the Brain

“Each side of the brain is able to perform and chooses to perform a certain set of cognitive tasks which the other side finds difficult, distasteful or both. In considering the nature of the two sets of functions, it appears that they may be logically incompatible. The right (non-language, in most of the population) hemisphere synthesizes over space. The left (language, in most of the population) analyzes over time. The right hemisphere does visual similarities to the exclusion of conceptual similarities. The left hemisphere does the opposite. The right hemisphere perceives form, the left hemisphere, detail. The right hemisphere codes sensory input in terms of images, the left hemisphere in terms of linguistic descriptions…”
