Famous quotes containing the words involved, growth and/or factors:

    “Why does philosophy use concepts and why does faith use symbols if both try to express the same ultimate? The answer, of course, is that the relation to the ultimate is not the same in each case. The philosophical relation is in principle a detached description of the basic structure in which the ultimate manifests itself. The relation of faith is in principle an involved expression of concern about the meaning of the ultimate for the faithful.”
    —Paul Tillich (1886–1965)

    “A person of mature years and ripe development, who is expecting nothing from literature but the corroboration and renewal of past ideas, may find satisfaction in a lucidity so complete as to occasion no imaginative excitement, but young and ambitious students are not content with it. They seek the excitement because they are capable of the growth that it accompanies.”
    —Charles Horton Cooley (1864–1929)

    “The economic dependence of woman and her apparently indestructible illusion that marriage will release her from loneliness and work and worry are potent factors in immunizing her from common sense in dealing with men at work.”
    —Mary Barnett Gilson (1877–?)
