Hi everyone, I posted this elsewhere and got an interesting debate going. Although MY conclusion was no one else's hahaha...
First you need to know something about Synesthesia. There's a very interesting bbc documentary ' Derek Tastes Like Earwax" , which encapsulates it quite nicely. Synesthesia affects about 1% of the population and there are numerous types. It's basically a mixing of ones senses. There's a man that actually experiences taste when most words are said...unfortunately the word Derek, tastes like earwax!..ugh.
There's another type of synesthesia that I based my 'thought' experiment on. There are synethetes that have what are called 'number lines'. Some see numbers, or months of the year for example in spacial 3d forms. They actually see 'out there' in the real world a line that has let's say the months of the year, in brightly colored segments that go on into infinity. Each individual with this form of synesthesia has there own unique number line. The present explanation for this, is that their brains have evolved differently than the 'norm' and are 'miswired'.
Now to me this sounds extremely arbitrary? Is reality merely based on a majority rule basis? Who's to say that it isn't the rest of us that has miswired brains and that we 'should' all have number lines?
So back to the question...if the majority of us had evolved with this type of synesthesia would number lines be considered real, or an illusion. I say it's quite obvious that to that world ( maybe it actually exists if Hugh Everett is right) it would be those that didn't have their own number line that would be considered interpreting reality falsely.
Anyway....I find it an interesting question. Charles Bonnet Syndrome could be another example of the "majority rule' reality we conform to but we won't go off in that direction yet.
