Those examples certainly seem to reject magic and theism entirely.\n\nPlausibility has a lot to do with style. We want to hear about monsters, but they go down better when the narrator is /real/: a grubby criminal, maybe, or a hard-boiled detective character we've been trained to accept just for the pleasure of it. (Once, we would have accepted a straight-laced scientist, but no more.) So many SF short stories involve the subversion of rules that ground the story in something we can recognize. Tolkien took the opposite approach, replacing the usual rules with his own, but maintaining a certain distance through the use of language; he never let you forget for long that you were experiencing something more \"real\" than history, but also just as large as history.\n\nWolfe is a stylist above all else, but also a moralist. He seems to see humans as half-truth-telling, /story-/telling beings in a universe of unplumbed moral and physical depth. Stories are what we are, and moral is what we want to be, so he retells old stories that test morality; I wouldn't say he's obsessed with the supernatural, but his awareness of it (and conviction in it) leads him to respect material reality while considering it secondary. If the story always comes first, the result can't ever be hard SF.\n\nAnother point I could make is that plausibility is in a sense a negative. That is, if I don't ever /say /that a pound of feathers weighs less than a pound of lead, I can't be caught being implausible. Wolfe's engineer side may nix some ideas produced by his mythographer side, but it rarely writes the stories.\n\nOn 11/28/2012 6:06 PM, Daniel Petersen wrote:"

At any rate, I don't think Wolfe's fiction reaches full 'hard' status for various reasons - regardless of whether we say hard s.f. by definition must remain mechanically non-theistic or non-magical or whatever.  But you describe well the tensions Wolfe manfully holds together.  It's part of what makes his work have a widespread, diverse audience.\n\n-DOJP\n_______________________________________________"

We all get a good chuckle out of that.\nThis can be recognized as a remnant of the colonial/imperialist thinking here on earth.\n\nI think Wolfe has turned this formula on its head. On first reading, we see there are some \nmystical explanations floating around Urth to explain Urth's dying sun. But as readers we\nunderstand that stars have a lifespan and Urth's sun has simply arrived at the end of one.\nSo for most of the story we have a scientific explanation for Urth's condition in mind.\n\nEventually, through the Green Man and Master Ash, we get the sense that there actually is\na solution to the dying sun. With Tzadkiel and Yesod and the white fountain cancelling out\nthe black hole we have the \"scientific\" solution to the problem. But it isn't human beings\nusing science who facilitate the solution. It is higher beings using what appears, even to\nus readers, as some sort of divine power.\n\nWhat I am suggesting is that  the premise of \"hard SF\" is that magic is the soft\nexplanation and science is the hard explanation.\n\nBut what Wolfe is doing is suggesting that to a divine intelligence, science is a soft, magical\nprimitive way of understanding the universe. There is a harder, more comprehensive \nunderstanding than science to those higher beings who can grasp it.\n\nSo, I think, from Wolfe's own perspective, he is not really writing Fantasy/SF.  He is writing \nSF which takes \"hard\" to a new level and definition. As science is harder than magic, so Wolfe\nfeels there is a divine knowledge which is harder than science. (I don't mean to suggest Wolfe\nis alone in taking this approach) \t\t \t   \t\t  "

It is /scientific /in the sense of \nbeing or embracing a principled, methodical quest for understanding.\n\nBut I think a better terminology might be to say it is /rational. /I \nassume that one of the attractions of Catholicism to Wolfe is its blend \nof the rational with the religious, even mystical, as well as with the \nmoral. Severian observes and records and speculates and may even have \ninsights, but he does not experiment or do maths, nor does he \ndistinguish the products of scientific work from the products of \ntheological work. Rationality---or rational morality---is the common \nthread.\n\nI don't think it's coincidental that he is somewhat in the position of \nGalileo and Kepler, who could observe and speculate, but even with \nmathematics were unable to conduct experiments to prove that the earth \ncircled the sun. That's more or less where the Commonwealth is in \nunderstanding the universe, give or take a few alien technologies and \nancient records."
