"Every science begins as philosophy and ends as art."

“A sensation is the feeling of an external stimulus or an internal condition.”

“Water is the usual drink, but everyone has wine, for no civilization has found life tolerable without narcotics or stimulants.”

“Civilization begins with order, grows with liberty, and dies with chaos.”

“Life is that which can hold a purpose for three thousand years and never yield. The individual fails, but life succeeds. The individual is foolish, but life holds in its blood and seed the wisdom of generations. The individual dies, but life, tireless and undiscourageble, goes on, wondering, longing, planning, trying, mounting, longing.”

“As we find a place in the economic world the rebellion of youth subsides; we disapprove of earthquakes when our feet are on the earth. We forget then the radicalism then in a gentle liberalism — which is radicalism softened with the consciousness of a bank account.”

“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; because of every element of 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.”
