Famous quotes containing the words threat and/or level:
“A piece of advice always contains an implicit threat, just as a threat always contains an implicit piece of advice.”
—José Bergamín (1895–1983)
“It is only for a little while, only occasionally, methinks, that we want a garden. Surely a good man need not be at the labor to level a hill for the sake of a prospect, or raise fruits and flowers, and construct floating islands, for the sake of a paradise. He enjoys better prospects than lie behind any hill. Where an angel travels it will be paradise all the way, but where Satan travels it will be burning marl and cinders.”
—Henry David Thoreau (1817–1862)
