All grammar aside, If " A implies B" is a true statement, then, "NotB implies NotA is also a true statement. However we can not say that If "A implies B" then "NotA implies NotB" is true.

To diagram the situation:
A --> B (True) Then
NotB --> NotA (True) [This is called the contrapositive]
B --> A (Not necessarily True) [This is called the Converse]
NotA --> NotB (Not necessarily True) [This is called the Inverse]

I hope this helps, ignore it if not. Of the logic I'm sure, the rest?

wake-up call.

a b nona nonb a->b nonb->nona
0 0 1 1 1 1
0 1 1 0 1 1
1 0 0 1 0 0
1 1 0 0 1 1

deci a->b=nonb->nona. muah.

logic allows you to make certain mistakes.

forgive geeks. they just want to have the illusion of ultimate truths.

nona kisses nonb and lets falsity have its way of implying virtualy anything.
