“Study the historian before you begin to study the facts.”

“History consists of a corpus ascertained facts. The facts are available to the historian in documents, inscriptions and so on, like fish in the fishmonger's slab. The historian collects them, takes them home, and cooks and serves them in whatever style appeals to him.”

“Immature thought is predominately purposive and utopian. Thought which rejects purpose altogether is the thought of old age. Mature thought combines purpose with observation and analysis.”

“If we can widen the range of experiences beyond what we as individuals have encountered, if we can draw upon the experiences of others who've had to confront comparable situations in the past, then - although there are no guarantees - our chances of acting wisely should increase proportionately.”

“Aprender acerca del presente a la luz del pasado quiere también decir aprender del pasado a la luz del presente. La función de la historia es la de estimular una mas profunda comprensión tanto del pasado como del presente por su comparación recíproca.”

“History is the long struggle of man, by exercise of his reason, to understand his environment and to act upon it. But the modern period has broadened the struggle in a revolutionary way. Man now seeks to understand, and act on, not only his environment, but himself; and this has added, so to speak, a new dimension to reason and a new dimension to history.”

“You can't study the darkness by flooding it with light.”
