@belen – “How do you believe two different things at once?”
– I would have thought that’s called “intelligence” – being able to hold two different viewpoints in one’s mind, without cognitive dissonance. Just to say, this position says this, and that position says that.
“what works for you” is a good test of something I think. The whole point of it is, it’s supposed to work for you.
To be able to understand another persons’ belief (or lack of), one that is different to your own, is where intelligence comes in. Holding two contradictory beliefs simultaneously as correct is called double-think. When the person starts to realize that their beliefs are mutually exclusive and starts to feel an unease without quite yet figuring out that both beliefs cannot be correct, that sense of unease is cognitive dissonance.
