The only reason why we wish to exchange thoughts is that we are different. If we were all the same, we would die dumb. No thought would be expressed after we found that our thoughts were precisely alike. We differ — our thoughts are different. Therefore the commerce that we call conversation.
Robert Green Ingersoll (1833-1899) American lawyer, agnostic, orator
“The Limits of Toleration,” Speech, Nineteenth Century Club of New York (8 May 1888)
