"If you read enough biography and history, you learn how people have dealt successfully or unsuccessfully with similar situations or patterns in the past. It doesn't give you a template of answers, but it does help you refine the questions you have to ask yourself."

"No great man lives in vain. The history of the world is but the biography of great men."

"There is properly no history; only biography."

"Those who have no record of what their forebears have accomplished lose the inspiration which comes from the teaching of biography and history."

"Read no history: nothing but biography, for that is life without theory."
