Famous quotes containing the words path and/or integral:

    “So long as you are praised think only that you are not yet on your own path but on that of another.”
    —Friedrich Nietzsche (1844–1900)

    “Painting myself for others, I have painted my inward self with colors clearer than my original ones. I have no more made my book than my book has made me—a book consubstantial with its author, concerned with my own self, an integral part of my life; not concerned with some third-hand, extraneous purpose, like all other books.”
    —Michel de Montaigne (1533–1592)
