this is such baloney… truth is personal experience, not received information… what this chart shows is not truth, but information and how the information can be analyzed in two different ways, actually out of an infinite number of ways, if the angles of the screens the images are projected on are changed, which amounts to mental perception, based on personal history and prejudices… direct experience of the cylinder in the drawing would be truth… notice that the shadows on the screens are just like Plato's cave story of the shadows of reality on the walls
