People have been trying to locate the human soul in its physical form for centuries, and over time people have theorized that our conscience, intelligence and spirit are all physical forces within us, detectable and extractable as necessary.
But as science advanced so too did our understanding of these intangible forces within us all, and those who pursued the unseen were forced to face the reality that these forces within us cannot be touched.
To See Or Not To See is a strange animated short created by Czech animator Bretislav Pojar in 1969 and released by The National Film Board of Canada. It's rendered in a cool modern art style and totally reminds me of the animated shorts they used to show on Sesame Street back in the 70s.
