Famous quotes containing the word primary:

    “Without the Constitution and the Union, we could not have attained the result; but even these, are not the primary cause of our great prosperity. There is something back of these, entwining itself more closely about the human heart. That something, is the principle of “Liberty to all”Mthe principle that clears the path for all—gives hope to all—and, by consequence, enterprize [sic], and industry to all.”
    —Abraham Lincoln (1809–1865)

    “The primary imperative for women who intend to assume a meaningful and decisive role in today’s social change is to begin to perceive themselves as having an identity and personal integrity that has as strong a claim for being preserved intact as that of any other individual or group.”
    —Margaret Adams (b. 1916)

    “But the doctrine of the Farm is merely this, that every man ought to stand in primary relations to the work of the world, ought to do it himself, and not to suffer the accident of his having a purse in his pocket, or his having been bred to some dishonorable and injurious craft, to sever him from those duties.”
    —Ralph Waldo Emerson (1803–1882)
