Well, there's a difference between visualising and conceptualising something. How can a mathematician conceptulise an imaginary number? He can never see it and any mental image he associates with it can only be make believe.Quote:
by dream, I don't mean picture it when asleep. I suppose I'm refering to the conceiving in the first place. How can physicist grasp the concept of multiple dimensions without visual reference?
My personal belief is that we cannot visualise anything that we have not previously experienced (in other words, we cannot imagine experiencing something we have not actually experienced). However, we can conceptualise concepts in an abstract fashion by (somehow) making an intuitive leap to do so.
I think this may be an exception to my "visualisation" rule...Obviously our brains are designed to perceive colour and something could trigger those sensations even when we've always been blind. That's different, however, from a blind man visualising an elephant (for instance) which our brains are not specially designed to perceive.Quote:
Blind people can see colours. The don't know the names for them if they've been blind all their lives, but there are stories of people that gain sight they've never had and recognise colours they saw whilst blind.
You may be right (Kedaman seems to think so), but I just don't see how our minds can create something out of nothing. Imagine trying to do that with a computer program? It's effectively having the ability to break with cause and effect and that's very hard to conceive of.Quote:
I believe imagination can generate things that we have no experience of, but as I said earlier, I am more inclined to believe that experience makes these concepts possible.
