Robert Green Ingersoll (1833-1899) was an American lawyer, political leader and orator noted for his high cultural level, his critique of religion and his defense of agnosticism. Nicknamed The Great Agnostic he was one of the leading figures during the Golden Age of Freethought in the United States in the late nineteenth century, and his radical stance on many controversial issues earned him many enemies and detractors in the most conservative sectors of North American society.
Although his speech focused mainly on the fields of politics and religion, Robert G. Ingersoll also lavished on other currents such as philosophical, leaving phrases like "Happiness is not a reward - it is a consequence. Suffering is not a punishment - it is a result."; or naturist, as in the case of this famous quote.
