Famous quotes containing the words necessity and/or sufficiency:
“The human condition is such that pain and effort are not just symptoms which can be removed without changing life itself; they are the modes in which life itself, together with the necessity to which it is bound, makes itself felt. For mortals, the “easy life of the gods” would be a lifeless life.”
—Hannah Arendt (1906–1975)
“Our age is very cheap and intelligible. Unroof any house, and you shall find it. The well-being consists in having a sufficiency of coffee and toast, with a daily newspaper; a well glazed parlor, with marbles, mirrors and centre-table; and the excitement of a few parties and a few rides in a year.”
—Ralph Waldo Emerson (1803–1882)
