—Ezra Pound (1885–1972)
“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)
“Upon the whole, necessity is something, that exists in the mind, not in objects; nor is it possible for us ever to form the most distant idea of it, consider’d as a quality in bodies. Either we have no idea of necessity, or necessity is nothing but that determination of thought to pass from cause to effects and effects to causes, according to their experienc’d union.”
—David Hume (1711–1776)
