Understanding Is A Kind of Ecstacy

‘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 we think well, we feel good. Understanding is a kind of ecstasy.’

Carl Sagan
American astronomer, cosmologist, astrophysicist, astrobiologist, author, science popularizer, and science communicator in astronomy and other natural sciences
