I'm a subscriber to oreilly's wonderful safari service. For a small(ish) fee I get to pick 10 book titles a month that I can read on line. This is ideal for me since I like to pick at books rather than read them from cover to cover. The books that I really like get added to my large oreilly book shelf. Yes I do have so many oreilly books that they need there own book shelf (and then some!).
Anyway getting back to the point of this post (do they ever have a point ?) one of my current books is the intriguingly tilted Mind Hacks. No this isn't an LSD users manual, no it's more a sort of neural biology for beginners book. There are lots of little experiments in it to show why we perceive the world the way we do.
I'm currently reading the chapter on Seeing. This makes me realise that eye's actually have very little to do with the way we see. Odd statement to make I know, but it's true. The image we get in our heads, is very heavily processed by the brain. The image that arrives on our retina is very different.
'Good eyesight has little to do with the eyes' or something like that is a quote from the radio series of Star Wars Episode 4 (yes there was a radio version of it!), seems very appropriate here.
This also has an interesting implication if taken to the extreme, since every ones mind will work a little differently, that means that everyones perception of reality could be slightly different. And since this is real to them there is no 'absolute' reality and each person carries around in there head, there own version of the world.
Sounds like there is a story idea in there some where....
