Poor amkerman. I guess he didn't expect to run into people who actually know what the fuck they're talking about. (Not including myself among them, I hasten to add, at least not when it comes to the technicalities of formal logic.)

I wonder, amkerman, if you could tell me if either of these arguments are valid, in your opinion:

    If God exists, he is a square circle.
    Square circles exist.
    Therefore, God may exist (as a square circle)



    If God exists, he is a square circle.
    God exists.
    Therefore, a square circle exists.

(Hint: The correct answer is "Yes, they are valid.")
