Famous quotes containing the words disease and/or associations:
“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)
“Hardly a man in the world has an opinion upon morals, politics or religion which he got otherwise than through his associations and sympathies. Broadly speaking, there are none but corn-pone opinions. And broadly speaking, Corn-Pone stands for Self- Approval. Self-approval is acquired mainly from the approval of other people. The result is Conformity.”
—Mark Twain [Samuel Langhorne Clemens] (1835–1910)
