Famous quotes containing the words rational and/or function:
“After I went to bed I had a curious fancy as to dreams. In sleep the doors of the mind are shut, and thoughts come jumping in at the windows. They tumble headlong, and therefore are so disorderly and strange. Sometimes they are stout and light on their feet, and then they are rational dreams.”
—James Boswell (1740–1795)
“The information links are like nerves that pervade and help to animate the human organism. The sensors and monitors are analogous to the human senses that put us in touch with the world. Data bases correspond to memory; the information processors perform the function of human reasoning and comprehension. Once the postmodern infrastructure is reasonably integrated, it will greatly exceed human intelligence in reach, acuity, capacity, and precision.”
—Albert Borgman, U.S. educator, author. Crossing the Postmodern Divide, ch. 4, University of Chicago Press (1992)
