Famous quotes containing the words rooting, tree and/or life:
“We should have learnt by now that laws and court decisions can only point the way. They can establish criteria of right and wrong. And they can provide a basis for rooting out the evils of bigotry and racism. But they cannot wipe away centuries of oppression and injustice—however much we might desire it.”
—Hubert H. Humphrey (1911–1978)
“Is not disease the rule of existence? There is not a lily pad floating on the river but has been riddled by insects. Almost every shrub and tree has its gall, oftentimes esteemed its chief ornament and hardly to be distinguished from the fruit. If misery loves company, misery has company enough. Now, at midsummer, find me a perfect leaf or fruit.”
—Henry David Thoreau (1817–1862)
“I have heard a good many pretend that they are going to die; or that they have died, for aught that I know. Nonsense! I’ll defy them to do it. They have n’t got life enough in them.... Only half a dozen or so have died since the world began.”
—Henry David Thoreau (1817–1862)
