Famous quotes containing the words internal and/or workings:

    “We all run on two clocks. One is the outside clock, which ticks away our decades and brings us ceaselessly to the dry season. The other is the inside clock, where you are your own timekeeper and determine your own chronology, your own internal weather and your own rate of living. Sometimes the inner clock runs itself out long before the outer one, and you see a dead man going through the motions of living.”
    —Max Lerner (b. 1902)

    “Standards of conduct appropriate to civil society or the workings of a democracy cannot be purely and simply applied to the Church.”
    —Joseph Ratzinger (b. 1927)
