Famous quotes containing the word physical:
“When we say that pleasure is the end, we do not mean the pleasure of the profligate or that which depends on physical enjoyment—as some think who do not understand our teachings, disagree with them, or give them an evil interpretation—but by pleasure we mean the state wherein the body is free from pain and the mind from anxiety.”
—Epicurus (c. 341–271 B.C.)
