Famous quotes containing the word thrust:

    “An image of its state;
    The wings half spread for flight,
    The breast thrust out in pride
    Whether to play, or to ride
    Those winds that clamour of approaching night.”
    —William Butler Yeats (1865–1939)

    “Freedom of choice for women, at the expense of the caring, warmth, and sensitivity to others so often associated with them, may be empty. In the thrust to redefine male and female roles, women must not become men; nor can men be permitted the continual dehumanization of their roles.”
    —Kathleen Weibel (b. 1945)

    “I have always been, am, and propose to remain a mere scholar. All that I have ever proposed to myself is to say, this and this I have learned; thus and thus have I learned it; go thou and learn better; but do not thrust on my shoulders the responsibility for your own laziness if you elect to take, on my authority, conclusions the value of which you ought to have tested for yourself.”
    —Thomas Henry Huxley (1825–95)
