RE: 2 Thought Experiments to Forever change the way you Look at the World + Philosophy Discussion

To make a very short answer, this sounds very much to the (probably very western) problem of "when a tree falls in the forest and there's nobody around, does it make noise?". Have a look at it on wikipedia.

Being very scientific minded, I would assume that makes very little difference between the twins, as "I" am the only reference for any measurement, so each twin can assume what s-he sees as "the truth". But that is only my opinion

Sort:  

Well, although it’s the hub of the nervous system and the ultimate terminus of every nerve, the brain itself lacks enervation and therefore cannot feel pain. As a result, once neurosurgeons dull the scalp with novacaine (or something equivalent) and fold the skin back, the patient feels no discomfort. (This is doubly strange since pain, no matter where it originates, is largely a mental phenomenon anyway. You can see this fact clearly with phantom limbs (link is external), which often ache or cramp up despite the lack of any actual flesh to feel the hurt.) So that’s one answer to why patients stay awake during neurosurgery: they’re unlikely to buck with pain, and if you can avoid the potential complications of putting someone under, you might as well.

Perception is a mental process. It's just can be based on physical things. When the tree falls, there are the properties for a noise to be noticed but without a perceiver there is no noise. It's a Schrödinger's cat event.
