Famous quotes containing the words set and/or theory:
“When parents fail to set appropriate limits, children may feel more vulnerable at night: the aggressive urges that have not been tamed by day may be terrifying to a small child alone in the dark.”
—Cathy Rindner Tempelsman (20th century)
“We have our little theory on all human and divine things. Poetry, the workings of genius itself, which, in all times, with one or another meaning, has been called Inspiration, and held to be mysterious and inscrutable, is no longer without its scientific exposition. The building of the lofty rhyme is like any other masonry or bricklaying: we have theories of its rise, height, decline and fallwhich latter, it would seem, is now near, among all people.”
—Thomas Carlyle (17951881)
