Famous quotes containing the words basic and/or assumption:
“Man has lost the basic skill of the ape, the ability to scratch its back. Which gave it extraordinary independence, and the liberty to associate for reasons other than the need for mutual back-scratching.”
—Jean Baudrillard (b. 1929)
“Many people operate under the assumption that since parenting is a natural adult function, we should instinctively know how to do it—and do it well. The truth is, effective parenting requires study and practice like any other skilled profession. Who would even consider turning an untrained surgeon loose in an operating room? Yet we “operate” on our children every day.”
—Louise Hart (20th century)
