Famous quotes containing the words natural and/or habitat:
“The remnant of Indians thereabout—all but exterminated in their recent and final war with regular white troops, a war waged by the Red Men for their native soil and natural rights—had been coerced into the occupancy of wilds not far beyond the Mississippi.”
—Herman Melville (1819–1891)
“Neither moral relations nor the moral law can swing in vacuo. Their only habitat can be a mind which feels them; and no world composed of merely physical facts can possibly be a world to which ethical propositions apply.”
