Thus, the surprise attack on Pearl Harbor, far from being a "strategic necessity," as the Japanese claimed even after the war, was a strategic imbeci… - Samuel Eliot Morison

After the Chesapeake incident, Jefferson lost the only chance of declaring war against Great Britain, when such a war would have secured unanimous support. Looking back on 1807 from a period of Hague conferences and arbitration treaties, Jefferson's moderation and restraint at that trying period seems most commendable. But the sequel proved that none of his expedients could prevent a war, which might far better have come in 1807, with the entire nation up in arms over the insult to its flag, than in 1812, after one section of the Union had been led by four years of commercial restriction into an attitude of violent disaffection. Instead of commencing reprisals or encour- aging the war spirit, Jefferson issued, on July 2, 1807, a proclamation closing American ports to British men-of-war, and expressing his confidence that Great Britain would apologize for the Leopard's action. The British government did acknowledge its fault, though somewhat ungraciously, and sent a special envoy to the United States to make reparation for the damage done, but with such conditions attached as to make it impossible for Jefferson to accept the offer.

Finally, the historian should have frequent recourse to the book of life. The richer his personal experience, the wider his human contacts, the more likely he is to effect a living contact with his audience. In writing, similes drawn from the current experience of this mechanical age, rather than those rifled from the literary baggage of past eras, are the ones that will go home to his reader. Service on a jury or a local committee may be a revelation as to the political thoughts and habits of mankind. A month’s labor in a modern factory would help any young academician to clarify his ideas of labor and capital. A camping trip in the woods will tell him things about Western pioneering that he can never learn in books. The great historians, with few exceptions, are those who have not merely studied, but lived; and whose studies have ranged over a much wider field than the period or subject of which they write.
