Optically Pure Air

Famous quotes containing the words pure and/or air:

    We are in fact convinced that if we are ever to have pure knowledge of anything, we must get rid of the body and contemplate things by themselves with the soul by itself. It seems, to judge from the argument, that the wisdom which we desire and upon which we profess to have set our hearts will be attainable only when we are dead and not in our lifetime.
    Socrates (469–399 B.C.)

    The thundering line of battle stands,
    And in the air Death moans and sings:
    But Day shall clasp him with strong hands,
    And Night shall fold him in soft wings.
    Julian Grenfell (1888–1915)
