Famous quotes containing the word number:

    Of all reformers Mr. Sentiment is the most powerful. It is incredible the number of evil practices he has put down: it is to be feared he will soon lack subjects, and that when he has made the working classes comfortable, and got bitter beer into proper-sized pint bottles, there will be nothing left for him to do.
    Anthony Trollope (1815–1882)

    States strong enough to do good are but few.
    Their number would seem limited to three.
    Robert Frost (1874–1963)

    The serial number of a human specimen is the face, that accidental and unrepeatable combination of features. It reflects neither character nor soul, nor what we call the self. The face is only the serial number of a specimen.
    Milan Kundera (b. 1929)
