After receiving an unsolicited PM by a member whose identity I won't disclose, let's call him/her Person X, it has transpired that this user has a PhD in a very respected field of knowledge.
From what I could get from his/her interventions in this forum I didn't think that his/her claim was true (in the very unlikely event that it was true it had to be a Bogdanoff affair kind of PhD, or maybe his/her advisor was from Social Text) so I put him/her up to a test.
Needless to say that Person X failed miserably.
You now have the chance to measure up against Person X, and remember that he/she has a PhD in very well thought field, and see if you can give the correct answer to the question.
I'll change the question a little bit, but the spirit of it will stay the same, so not to give away the identity of Person X.
Without further ado:
What is the truth value of the following proposition:
All three legged, red eyed, two headed Japanese eat red bananas.
Remember that you have to say what is the truth value of this proposition and justify why this is so.
Ps: After a few more PMs it has transpired that even though Person X has started his studies in the well thought and highly intellectual field he/she hasn't finished it, but (and bear with me here) he/she still has the skills.
Of course I won't quote and repeat directly what Person X has told me but do believe that this is a 100% accurate paraphrase of what Person X has said.

B = three legged, red eyed, two headed Japanese who red bananas
A != B

Originally posted by adam warlockyou people just don't have any sense of humor, I made a sarcastic comment which was misinterpreted by a guy who is arguably mentally unstable (given his history of threats and abusive behavior). thats all.
Now, now of course I won't tell you who Person X was, since it would be highly unethical on my part. 😵 😉
But you can always join the challenge. Truth value and justification.

Logical implication
Logical implication and the material conditional are both associated with an operation on two logical values, typically the values of two propositions, that produces a value of false just in the singular case the first operand is true and the second operand is false.
The truth table associated with the material conditional if p then q (symbolized as p → q) and the logical implication p implies q (symbolized as p ⇒ q) is as follows:
Logical Implication p q p-->q
1.T T T
2.T F F
3.F T T
4.F F T
p = "a being is three-legged, red-eyed, two-headed, and Japanese"
q = "it eats red bananas"
p-->q is thus true in all cases where:
(1) p & q are both true -- the mutant banana-eater exists, and this being does indeed eat red bananas
(3 & 4) p is false -- the mutant banana-easter doesn't exist.
p-->q is false ONLY if:
(2) p is true and q is false -- the mutant banana-eater exists, and this being never eats red bananas
