Famous quotes containing the words comparison with, comparison, multiple and/or pumps:

    [Girls] study under the paralyzing idea that their acquirements cannot be brought into practical use. They may subserve the purposes of promoting individual domestic pleasure and social enjoyment in conversation, but what are they in comparison with the grand stimulation of independence and self- reliance, of the capability of contributing to the comfort and happiness of those whom they love as their own souls?
    Sarah M. Grimke (1792–1873)

    We teach boys to be such men as we are. We do not teach them to aspire to be all they can. We do not give them a training as if we believed in their noble nature. We scarce educate their bodies. We do not train the eye and the hand. We exercise their understandings to the apprehension and comparison of some facts, to a skill in numbers, in words; we aim to make accountants, attorneys, engineers; but not to make able, earnest, great- hearted men.
    Ralph Waldo Emerson (1803–1882)

    ... the generation of the 20’s was truly secular in that it still knew its theology and its varieties of religious experience. We are post-secular, inventing new faiths, without any sense of organizing truths. The truths we accept are so multiple that honesty becomes little more than a strategy by which you manage your tendencies toward duplicity.
    Ann Douglas (b. 1942)

    the rusty
    Pump pumps over your sweating face the clear
    Water, cold, so cold! you cup your hands
    And gulp from them the dailiness of life.
    Randall Jarrell (1914–1965)
