Famous quotes containing the words genus, towering and/or vertical:

    “Methinks it would be some advantage to philosophy if men were named merely in the gross, as they are known. It would be necessary only to know the genus and perhaps the race or variety, to know the individual. We are not prepared to believe that every private soldier in a Roman army had a name of his own,—because we have not supposed that he had a character of his own.”
    —Henry David Thoreau (1817–1862)

    “When I was as you are now, towering in the confidence of twenty-one, little did I suspect that I should be at forty-nine, what I now am.”
    —Samuel Johnson (1709–1784)

    “I tell you, hopeless grief is passionless;
    That only men incredulous of despair,
    Half-taught in anguish, through the midnight air
    Beat upward to God’s throne in loud access
    Of shrieking and reproach. Full desertness,
    In souls as countries, lieth silent-bare
    Under the blanching, vertical eye-glare
    Of the absolute Heavens.”
    —Elizabeth Barrett Browning (1806–1861)
