This sufficient assumption question really has me thrown. I've read the Manhattan explanations on this, but I'm still having a hard time with understanding the whole question.
Conclusion: Money doesn't exist.
Why? The only thing you need for money to disappear is a universal loss of belief.
Gap seems to be that because something disappears it doesn't exist.
So Manhattan represented this in conditional logic as:
(loss of belief --> disappear) --> NOT exist
Easy enough, although it wasn't my instinct to put loss of belief as the sufficient condition. Still, with this conditional logic, I think I understand how (A) is the correct answer as the contrapositive.
Exist --> NOT (loss of belief --> disappear)
My problem is I'm having a hard time understanding what the necessary condition is saying here. What does NOT (loss of belief --> disappear) actually mean? Something can exist even if there isn't a loss of belief and it doesn't disappear? Also confused about how this works as a sufficient assumption answer, how does this prove that money doesn't exist? Any help?
As a side note, has anyone seen this conditional logic set up in other questions I can look at?
