"... is inspired by the only passage in Jean Paul Sartre's writings which has ever specifically concerned me – the passage from Nausea wherein the protagonist sits in a park and imagines his suicide." - S.B. Black Vision was made by Brakhage from the print he had struck of Sartre’s Nausea, re-editing it and embellishing it with ink and scratching. It is a silent 2.5 minute film and does not feature the voiceover included in Sartre's Nausea.
