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)

    Self-centeredness is a natural outgrowth of one of the toddler’s major concerns: What is me and what is mine...? This is why most toddlers are incapable of sharing ... to a toddler, what’s his is what he can get his hands on.... When something is taken away from him, he feels as though a piece of him—an integral piece—is being torn from him.
    Lawrence Balter (20th century)
