"Aldiss' New Wave masterpiece is Report On Probability A. … The minutiae of all the involved's lives are the only thing; the act of observation is the only plot. The science fiction happens when it becomes apparent that there are Other watchers, and watchers watching those watchers, stretching back to what seems to be citizens of our own reality. Report On Probability A is about the metaphor of circular vision, manifested in the narrative by the round fields of view of the various optical devices and windows through which S, G, and C observe their world, expanding macrocosmically with the vast circle of observers observing the observers. As banality merges with paranoia, drawn only by whatever the reader brings to the narrative, there is no conclusion, no story, only facts. The story returns over and over to the painting The Hireling Shepherd by Holman Hunt, which becomes a recurring unresolved image which has no final meaning, only whatever speculation it's benighted observers bring to bear on it. Every character is searching for a meaning which may, or may not, exist as actual Truth. Behind each level of truth lies another; who is to say how far the chain goes or which part of it is more Actual? … The simplicity of the "story" masks an investigation into uncertainty and the nature of reality itself. The seeming bankruptcy of plot opens the reader to question the act of observation, of reporting, of writing itself. Truth is what Report On Probability A is all about, and Aldiss points out that it is a plastic thing that depends on who is trying to figure it out, and an ambiguous thing that may, at it's root, be unknowable."
