His writings included thoughts about the soul.
He confirmed his love of and insight into the value of history, saying: “It is a mistake to think that the past is dead. Nothing that has ever happened is quite without influence at this moment. The present is merely the past rolled up and concentrated in this second of time. You, too, are your past; often, your face is your autobiography; you are what you are because of what you have been, because of your heredity stretching back into forgotten generations, and because of every element of the environment that has affected you, every man or woman that has met you, every book that you have read, every experience that you have had; all these are accumulated in your memory, your body, your character, your soul. So with a city, a country, and a race, it is its past and cannot be understood without it.”
