Ludwig von Mises in Human Action, claim:
"He who wants to live to see the later day, must first of all care for the preservation of his life in the intermediate period. Survive and appeasement of vital needs are thus requirements for the satisfaction of any wants in the remoter future."
Von Mises,Ludwig. (1966). Human Action. Chicago: Henry Regnery, 3rd rev. ed. p. 486.
