What is Religion?
Robert Ingersoll (1833 – 1899) was an American lawyer, a Civil War veteran, political leader, and orator of the United States during the Golden Age of Free Thought, noted for his broad range of culture and his brilliant defense of agnosticism. He was nicknamed "The Great Agnostic".
Ingersoll was known for his passionate and articulate speeches that were often delivered in packed auditoriums across the US to rapt audiences. Here I read one of his famous speeches on religion (it begins 17 seconds in). You can also download the speech from my Soundcloud.
