Famous quotes containing the words water, activity and/or content:
“A man’s social and spiritual discipline must answer to his corporeal. He must lean on a friend who has a hard breast, as he would lie on a hard bed. He must drink cold water for his only beverage. So he must not hear sweetened and colored words, but pure and refreshing truths. He must daily bathe in truth cold as spring water, not warmed by the sympathy of friends.”
—Henry David Thoreau (1817–1862)
“... the will always wills to do something and thus implicitly holds in contempt sheer thinking, whose whole activity depends on “doing nothing.””
—Hannah Arendt (1906–1975)
“Strange that so few ever come to the woods to see how the pine lives and grows and spires, lifting its evergreen arms to the light,—to see its perfect success; but most are content to behold it in the shape of many broad boards brought to market, and deem that its true success! But the pine is no more lumber than man is, and to be made into boards and houses is no more its true and highest use than the truest use of a man is to be cut down and made into manure.”
—Henry David Thoreau (1817–1862)
