I’ve written a bit about what you might expect in the various sections of this electronic publication in the first posting of each section. They might contain pieces with different sorts of viewpoints. For instance postings in Parable Worlds might be fiction written as if they were totally true. You might not know in that section which ones are speculative and which ones are on the fringe of the believable. Other sections like Parable Universe are nonfiction.
The nature of Parable Worlds is such that suspension of disbelief is important and not knowing where the line of fiction, believable, and unbelieveable truth is important. Then you can be the judge. There will be other places where proofs, evidence, and citations are necessary and important. Parable Worlds is an odd place where you are the one to seek out those things.
