"I felt more keenly than before the need of a philosophy that would do justice to the infinite vitality of nature. In the inexhaustible activity of the atom, in the endless resourcefulness of plants, in the teeming fertility of animals, in the hunger and movement of infants, in the laughter and play of children, in the love and devotion of youth, in the restless ambition of fathers and the lifelong sacrifice of mothers, in the undiscourageable researches of scientists and the sufferings of genius, in the crucifixion of prophets and the martyrdom of saints — in all things I saw the passion of life for growth and greatness, the drama of everlasting creation. I came to think of myself, not as a dance and chaos of molecules, but as a brief and minute portion of that majestic process... I became almost reconciled to mortality, knowing that my spirit would survive me enshrined in a fairer mold... and that my little worth would somehow be preserved in the heritage of men. In a measure the Great Sadness was lifted from me, and, where I had seen omnipresent death, I saw now everywhere the pageant and triumph of life."

“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.”
