Famous quotes containing the words tools and/or devices:

    “The besetting sin of able men is impatience of contradiction and of criticism. Even those who do their best to resist the temptation, yield to it almost unconsciously and become the tools of toadies and flatterers. “Authorities,” “disciples,” and “schools” are the curse of science and do more to interfere with the work of the scientific spirit than all its enemies.”
    —Thomas Henry Huxley (1825–95)

    “The gods being always close to men perceive those who afflict others with unjust devices and do not fear the wrath of heaven.”
    —Hesiod (c. 8th century B.C.)
