Famous quotes containing the words plastic and/or number:

    What a wonderful faculty is memory!—the most mysterious and inexplicable in the great riddle of life; that plastic tablet on which the Almighty registers with unerring fidelity the records of being, making it the depository of all our words, thoughts and deeds—this faithful witness against us for good or evil.
    Susanna Moodie (1803–1885)

    I think, for the rest of my life, I shall refrain from looking up things. It is the most ravenous time-snatcher I know. You pull one book from the shelf, which carries a hint or a reference that sends you posthaste to another book, and that to successive others. It is incredible, the number of books you hopefully open and disappointedly close, only to take down another with the same result.
    Carolyn Wells (1862–1942)
