In 1977 at a science fiction convention in Metz, France, Philip K. Dick delivered a lecture about his concept of orthogonal time titled “If You Find This World Bad You Should See Some of the Others”. The audience was described as leaving the auditorium looking like they’d been hit with a hammer. The event was filmed, and you can see the whole thing complete with French interpretation (except for a sentence or two at the end) or a version with the translator cut out (and missing a bit of the intro). Or you can read the longer, unexpurgated essay online. On an episode of their podcast Weird Studies, J. F. Martel and Phil Ford put the lecture in context of Dick’s life, and larger currents of thought. Finally, a comparatively normal interview with Dick was filmed in Metz (transcript here).
