Famous quotes containing the word power:
“What I think the political correctness debate is really about is the power to be able to define. The definers want the power to name. And the defined are now taking that power away from them.”
—Toni Morrison (b. 1931)
“It does not follow ... that the right to criticize Shakespeare involves the power of writing better plays. And in fact—do not be surprised at my modesty—I do not profess to write better plays.”
—George Bernard Shaw (1856–1950)
“For do but note a wild and wanton herd
Or race of youthful and unhandled colts
Fetching mad bounds, bellowing and neighing loud,
Which is the hot condition of their blood;
If they but hear perchance a trumpet sound,
Or any air of music touch their ears,
You shall perceive them make a mutual stand,
Their savage eyes turned to a modest gaze
By the sweet power of music.”
—William Shake{peare (1564–1616)
