@Frank Apisa,
Quote: IF you actually are a Frenchman living in France...then I am wrong in my supposition that you are actually an American (or Canadian) woman.
That is a qualified comment...and there is no guess involved.
I can spot quite a few guesses in there. Funny you can't see that...
1. You're talking to me as if you were certain that I exist; and 2. as if you were certain I am a human being to whom consideration of gender and nationality apply.
By your own standard of what can be know about reality, I could be a figment of your imagination, or a computer, or a dolphin, or a god.
3. You guess that IF I am French, I can't be Canadian or American, but I could have dual or triple nationalities...
4. Likewise, you are guessing that if I am a man, I am not a women. I could be androgynous...
5. Finally, you're making the total blind guess that logic can be trusted, that one actually can derive a "THEN" from an "IF", that propositions must be true or false, etc. As already explained to you, your trust in logic cannot be proven. It's a blind guess.
Every statement is a guess, by your definition of that term. QED
