"What light is to the eyes -- what air is to the lungs -- what love is to the heart, liberty is to the soul of man. Without liberty, the brain is a dungeon, where the chained thoughts die with their pinions pressed against the hingeless doors." | by: | Robert G. Ingersoll (1833-1899) American lawyer, Civil War veteran, political leader, orator of United States during the Golden Age of Free Thought, nicknamed "The Great Agnostic" |
