Famous quotes containing the word reading:
“There are worse crimes than burning books. One of them is not reading them.”
—Joseph Brodsky (b. 1940)
“After all, what is reading but a vice, like drink or venery or any other form of excessive self-indulgence? One reads to tickle and amuse one’s mind; one reads, above all, to prevent oneself thinking.”
