“The past, as we have been told so many times, is a foreign country where things are done differently. This may be true—indeed it patently is true when it comes to morals or customs, the role of women, aristocratic government, and a million other elements of our daily lives. But there are similarities, too. Ambition, envy, rage, greed, kindness, selflessness, and, above all, love have always been as powerful in motivating choices as they are today.”
