Famous quotes containing the word primary:

    “It was the feeling of a passenger on an ocean steamer whose mind will not give him rest until he has been in the engine-room and talked with the engineer. She wanted to see with her own eyes the action of primary forces; to touch with her own eyes the action of primary forces; to touch with her own hand the massive machinery of society; to measure with her own mind the capacity of the motive power. She was bent upon getting to the heart of the great American mystery of democracy and government.”
    —Henry Brooks Adams (1838–1918)

    “The primary distinction of the artist is that he must actively cultivate that state which most men, necessarily, must avoid: the state of being alone.”
    —James Baldwin (1924–1987)

    “If the accumulated wealth of the past generations is thus tainted,—no matter how much of it is offered to us,—we must begin to consider if it were not the nobler part to renounce it, and to put ourselves in primary relations with the soil and nature, and abstaining from whatever is dishonest and unclean, to take each of us bravely his part, with his own hands, in the manual labor of the world.”
    —Ralph Waldo Emerson (1803–1882)
