Famous quotes containing the words thread and/or form:
“I often wish for the end of the wretched remnant of my life; and that wish is a rational one; but then the innate principle of self-preservation, wisely implanted in our natures, for obvious purposes, opposes that wish, and makes us endeavour to spin out our thread as long as we can, however decayed and rotten it may be.”
—Philip Dormer Stanhope, 4th Earl Chesterfield (1694–1773)
“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.”
—Aldous Huxley (1894–1963)
