Famous quotes containing the word domains:
“I shall be a benefactor if I conquer some realms from the night, if I report to the gazettes anything transpiring about us at that season worthy of their attention,if I can show men that there is some beauty awake while they are asleep,if I add to the domains of poetry.”
—Henry David Thoreau (18171862)
