Famous quotes containing the word boundaries:

    We must be generously willing to leave for a time the narrow boundaries in which our individual lives are passed ... In this fresh, breezy atmosphere ... we will be surprised to find that many of our familiar old conventional truths look very queer indeed in some of the sudden side lights thrown upon them.
    Bertha Honore Potter Palmer (1849–1918)

    Whereas the Greeks gave to will the boundaries of reason, we have come to put the will’s impulse in the very center of reason, which has, as a result, become deadly.
    Albert Camus (1913–1960)

    The boundaries which divide Life from Death are at best shadowy and vague. Who shall say where the one ends, and where the other begins?
    Edgar Allan Poe (1809–1845)
