Famous quotes containing the word tonic:
“We need the tonic of wildness,—to wade sometimes in marshes where the bittern and the meadow-hen lurk, and hear the booming of the snipe; to smell the whispering sedge where only some wilder and more solitary fowl builds her nest, and the mink crawls with its belly close to the ground.”
—Henry David Thoreau (1817–1862)
“You are done for—a living dead man—not when you stop loving but stop hating. Hatred preserves: in it, in its chemistry, resides the “mystery” of life. Not for nothing is hatred still the best tonic ever discovered, for which any organism, however feeble, has a tolerance.”
—E.M. Cioran (b. 1911)
