Famous quotes containing the word rapid:

    “Missionaries, whether of philosophy or religion, rarely make rapid way, unless their preachings fall in with the prepossessions of the multitude of shallow thinkers, or can be made to serve as a stalking-horse for the promotion of the practical aims of the still larger multitude, who do not profess to think much, but are quite certain they want a great deal.”
    —Thomas Henry Huxley (1825–95)
