Famous quotes containing the words space and/or spaces:

    “For tribal man space was the uncontrollable mystery. For technological man it is time that occupies the same role.”
    —Marshall McLuhan (1911–1980)

    “When I consider the short duration of my life, swallowed up in the eternity before and after, the little space which I fill and even can see, engulfed in the infinite immensity of spaces of which I am ignorant and which know me not, I am frightened and am astonished at being here rather than there. For there is no reason why here rather than there, why now rather than then.”
    —Blaise Pascal (1623–1662)
