“We are an intelligent species and the use of our intelligence quite properly gives us pleasure. In this respect the brain is like a muscle. When it is in use we feel very good. Understanding is joyous.”    

–Carl Sagan (American Astronomer and Science Writer, 1934-1996)


“Broca’s Brain: Reflections on the Romance of Science” (Carl Sagan)
