Could you give me an example of a belief that is consistent with reality but false?
I'm definitely having more trouble than I expected. Unicorns have 5 legs... does that count? You're making me doubt myself.
Cool. : )
Is "Unicorns have 5 legs" consistent with reality? I would be quite surprised to find out that it was.
Well it doesn't seem to be inconsistent with reality.
It doesn't even have any referents to reality. It's not even a statement about whatever "reality" we live in, to the best of my knowledge. If it does mean five-leggedness of unicorn creatures with the implication of the existence of possible-existence of such creatures in reality, then it is false, but it's inconsistent with what we know of reality, since there's no way such a creature would exist.
...I think, anyway. Not quite sure about that second part.
The non-existence of unicorns makes the claim that they have legs, in whatever number, inconsistent with reality.
