Famous quotes containing the words false, negative and/or result:
“I am well acquainted with your manner of wrenching the true
cause the false way.”
—William Shakespeare (1564–1616)
“The working woman may be quick to see any problems with children as her fault because she isn’t as available to them. However, the fact that she is employed is rarely central to the conflict. And overall, studies show, being employed doesn’t have negative effects on children; carefully done research consistently makes this clear.”
—Grace Baruch (20th century)
“The innocence of those who grind the faces of the poor, but refrain from pinching the bottoms of their neighbour’s wives! The innocence of Ford, the innocence of Rockefeller! The nineteenth century was the Age of Innocence—that sort of innocence. With the result that we’re now almost ready to say that a man is seldom more innocently employed than when making love.”
—Aldous Huxley (1894–1963)
