In dealing with humanity’s inquiry, the science of history up to now is like money in circulation⁠—paper money and coin. The biographies and special national histories are like paper money. They can be used and can circulate and fulfill their purpose without harm to anyone and even advantageously, as long as no one asks what is the security behind them. You need only forget to ask how the will of heroes produces events, and such histories as Thiers’ will be interesting and instructive and may perhaps even possess a tinge of poetry. But just as doubts of the real value of paper money arise either because, being easy to make, too much of it gets made or because people try to exchange it for gold, so also doubts concerning the real value of such histories arise either because too many of them are written or because in his simplicity of heart someone inquires: by what force did Napoleon do this?⁠—that is, wants to exchange the current paper money for the real gold of actual comprehension.
