Famous quotes containing the words size and/or sample:

    “Delusions that shrink to the size of a woman’s glove,
    Then sicken inclusively outwards:
    . . . the incessant recital
    Intoned by reality, larded with technical terms,
    Each one double-yolked with meaning and meaning’s rebuttal:

    —Philip Larkin (1922–1986)

    “The present war having so long cut off all communication with Great-Britain, we are not able to make a fair estimate of the state of science in that country. The spirit in which she wages war is the only sample before our eyes, and that does not seem the legitimate offspring either of science or of civilization.”
    —Thomas Jefferson (1743–1826)
