Video: Buster Keaton in a scene from
THE DIFFICULTY OF LIVING IN THE PRESENT
Most people…still cling to what I call the rearview-mirror view of their world. By this I mean to say that because of the invisibility of any environment during the period of its innovation, man is only consciously aware of the environment that has preceded it; in other words, an environment becomes fully visible only when it has been superseded by a new environment; thus we are always one step behind in our view of the world.
(an aside, when the front of the building falls on Keaton, if you look close, the window brushes his elbow. He doesn't even flinch...)
