The history of mankind is the story of the triumph of reason over superstition, of knowledge over belief, of fact over prejudice, and the progress of mankind is but the result of that triumph. In every area of human endeavor, advancement has come only with the crumbling of the barriers of ignorance. It has been so with science, with religion, with industrial technology and with human relations, and it is still so today. The struggle for enlightenment and justice has been and is the great issue of the age.
