Famous quotes containing the word lye:

    “We all cry out that the world is corrupt,—and I fear too justly,—but we never reflect, what we have to thank for it, and that it is our open countenance of vice, which gives the lye to our private censures of it, which is its chief protection and encouragement.”
    —Laurence Sterne (1713–1768)
