Is art the highest human achievement, or is just the product of a messed up brain?
messed up? Relative to what way of functioning? As if there was an absolute one.Think again.
I don't think it is "messed up" as such.I think creativity comes from randomization, and randomization can come from lots of directions. Some of them are healthier than others.
Isn't it just a personality trait, that people possess to varying degrees? Why would it mean they have a messed up brain? Maybe if the person were an artistic savant...
No, creativity is not randomness. It is the ability to see things from many perspectives, to rearrange them in orders that are not always linear, but there is an order to them nonetheless.
Well, yes, of course you're right. I think the basis for creativity IS randomness, but once the randomness is produced you still have to notice it, evaluate it, judge it, use it. The ability you mentioned is very important but it works with the raw material it's given, and that raw material is primarily produced by randomness. And perhaps secondarily produced by primary process - but now we're getting pretty psychoanalytic.
