    More generally, when two people disagree about whether sentence A implies sentence B, it will always never be a disagreement about whether proposition P implies proposition Q, almost always a...

    You are contradicting yourself.

    It has to be significant that the only one to find that the question doesn't make sense is also the one who has a training in mathematical logic.

    Any other definition is equivocation.

    This definition makes the argument invalid.

    There is two senses of "immortal". In one sense, an immortal being is one that always will be, like the abrahamic God. In another, an immortal being is merely one that doesn't age and die of natural...

    Am I reading this right, no natural process produces O2? So where's it coming from?[/QUOTE]

    On a planet that didn't have oxygen in its atmosphere, true.
