John Sperling

“We should go forth on the shortest walk, perchance, in the spirit of undying adventure, never to return; prepared to send back our embalmed hearts only, as relics to our desolate kingdoms. If you are ready to leave father and mother, and brother and sister, and wife and child and friends, and never see them again; if you have paid your debts, and made your will, and settled all your affairs, and are a free man; then you are ready for a walk.”
― Henry David Thoreau, Walking

“This Only"

A valley and above it forests in autumn colors.
A voyager arrives, a map leads him there.
Or perhaps memory. Once long ago in the sun,
When snow first fell, riding this way
He felt joy, strong, without reason,
Joy of the eyes. Everything was the rhythm
Of shifting trees, of a bird in flight,
Of a train on the viaduct, a feast in motion.
He returns years later, has no demands.
He wants only one, most precious thing:
To see, purely and simply, without name,
Without expectations, fears, or hopes,
At the edge where there is no I or not-I.”
― Czeslaw Milosz

“Our novice runs the risk of failure without additional traits: a strong inclination toward originality, a taste for research, and a desire to experience the incomparable gratification associated with the act of discovery itself.”
― Santiago Ramón y Cajal, Advice for a Young Investigator

“To those human beings who are of any concern to me I wish suffering, desolation, sickness, ill-treatment, indignities—I wish that they should not remain unfamiliar with profound self-contempt, the torture of self-mistrust, the wretchedness of the vanquished: I have no pity for them, because I wish them the only thing that can prove today whether one is worth anything or not—that one endures.”
― Friedrich Nietzsche, The Will to Power
