I am not understanding. To read the dictionary does not require a
course in formal logic. The converse of the preceding statement is also true.
*******************************************************************
Just for clarification, If I recall correctly:
Conditional: If A then B
Converse: If B then A
Inverse: IF NOT A then NOT B
Contrapositive: IF NOT B then NOT A
If the conditional and converse are both true then a biconditional.

If I am all wet on any of this, please point out my errors. Many moons
have passed since I took predicate and formal logic.
Best Regards,
K.

had marveled over that mystery a long time. We had
followed the cows around for years - that is, in the
daytime - but had never caught them drinking fluid of
that color."
