I can allow for one completely unscientific thing to happen in a story before I start to lose interest. Okay, so someone has the power of cryomancy… still a nifty story.
[spoiler]Basically the idea is that knowledge of these corrupting influences (such as emotion, often responsible for the clouding of one’s judgment) should be removed from the typical person, however, there are memories of things which might be vital for society to still be aware of, if only concentrated within the mind of one trusted and honored individual, a keeper of memories.
This person can offer judgment against or for certain things, without everyone having to know in great detail why they are for or against a thing.
It’s basically the theory that the enlightened and great Leader knows best, and we the little people are infants too irresponsible to know anything.
All perfectly in line with a thought-controlling totalitarian society. Some thoughts are too dangerous for us to have, so someone else should have them. Everyone is the same, and equal, but some people are more equal than others.
If you remove the somewhat magical power from the story, and instead, these were physical storage devices containing data about these experiences, videos, sounds, and perhaps direct stimulus to the human brain resulting in flashes of emotion, would it be more interesting or plausible to you?[/spoiler]
