 The adage was inspired by Sturgeon's observation that while science fiction was often derided for its low quality by critics, the majority of examples of works in other fields could equally be seen to be of low quality, and science fiction was thus no different in that regard from other art.Some make a distinction between the revelation ("ninety percent of everything is crap") and the law ("nothing is always absolutely so").A similar adage appears in Rudyard Kipling's "The Light That Failed", published in 1890.
