Famous quotes containing the words human and/or disease:
“How like a prodigal doth nature seem,
When thou, for all thy gold, so common art!
Thou teachest me to deem
More sacredly of every human heart,
Since each reflects in joy its scanty gleam
Of Heaven, and could some wondrous secret show,
Did we but pay the love we owe,
And with a child’s undoubting wisdom look
On all these living pages of God’s book.”
—James Russell Lowell (1819–1891)
“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)
