Famous quotes containing the words tools and/or machine:

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 momentary charge at Balaklava, in obedience to a blundering command, proving what a perfect machine the soldier is, has, properly enough, been celebrated by a poet laureate; but the steady, and for the most part successful, charge of this man, for some years, against the legions of Slavery, in obedience to an infinitely higher command, is as much more memorable than that as an intelligent and conscientious man is superior to a machine. Do you think that that will go unsung?”
—Henry David Thoreau (1817–1862)
