- Books are humanity in print.
- Books are the carriers of civilization. Without books, history is silent, literature dumb, science crippled, thought and speculation at a standstill.
- Dead battles, like dead generals, hold the military mind in their dead grip.
- Diplomacy means all the wicked devices of the Old World, spheres of influence, balances of power, secret treaties, triple alliances, and, during the interim period, appeasement of Fascism.
- Every successful revolution puts on in time the robes of the tyrant it has deposed.
- Honor wears different coats to different eyes.
- No more distressing moment can ever face a British government than that which requires it to come to a hard, fast and specific decision.
- Nothing sickens me more than the closed door of a library.
- Reasonable orders are easy enough to obey; it is capricious, bureaucratic or plain idiotic demands that form the habit of discipline.
- To a historian libraries are food, shelter, and even muse.
