Famous quotes containing the words touch and/or switch:
“One touch of nature makes the whole world kin,
That all, with one consent, praise new-born gauds.
And give to dust that is a little gilt
More laud than gilt o’er dusted;
The present eye praises the present object.”
—William Shakespeare (1564–1616)
“Uncritical semantics is the myth of a museum in which the exhibits are meanings and the words are labels. To switch languages is to change the labels.”
—Willard Van Orman Quine (b. 1908)
