Famous quotes containing the words path and/or integral:

    “So-called “austerity,” the stoic injunction, is the path towards universal destruction. It is the old, the fatal, competitive path. “Pull in your belt” is a slogan closely related to “gird up your loins,” or the guns-butter metaphor.”
    —Wyndham Lewis (1882–1957)

    “... no one who has not been an integral part of a slaveholding community, can have any idea of its abominations.... even were slavery no curse to its victims, the exercise of arbitrary power works such fearful ruin upon the hearts of slaveholders, that I should feel impelled to labor and pray for its overthrow with my last energies and latest breath.”
    —Angelina Grimké (1805–1879)
