Famous quotes containing the words positioning and/or system:

    Genius differs from talent not by the amount of original thoughts, but by making the latter fertile and by positioning them properly, in other words, by integrating everything into a whole, whereas talent produces only fragments, no matter how beautiful.
    Franz Grillparzer (1791–1872)

    Such is the remorseless progression of human society, shedding lives and souls as it goes on its way. It is an ocean into which men sink who have been cast out by the law and consigned, with help most cruelly withheld, to moral death. The sea is the pitiless social darkness into which the penal system casts those it has condemned, an unfathomable waste of misery. The human soul, lost in those depths, may become a corpse. Who shall revive it?
    Victor Hugo (1802–1885)
