The Dragons of Eden

"There is no way to tell whether the patterns extracted by the right hemisphere are real or imaginary without subjecting them to left-hemisphere scrutiny. On the other hand, mere critical thinking, without creative and intuitive insights, without the search for new patterns, is sterile and doomed.

"To solve complex problems in changing circumstances requires the activity of both cerebral hemispheres; the path to the future lies through the corpus callosum."

-- Carl Sagan
