“The first public screening of the Lumiére brothers’ wondrous new moving-picture machine took place in Paris in March of 1895. This was the same year that a 39-year-old Viennese neurologist named Sigmund Freud published a co-authored book, with Joseph Breuer, called Studies on Hysteria. The two events might have seemed worlds apart at the time, but their historical coincidence now looks like providence: no medium would quite as potently suggest Freud’s emerging formulation of the unconscious and its nocturnal operations as the movies.”
