The appeal to the stone is one of those names I never quite understood. I tend to view myself as someone with the capacity for abstract thinking, but then again. Now, the appeal to the stone is a fallacy wherein a debater dismisses a claim or argument from his or her counterpart as absurd, without providing proof or argument of its absurdity.
This is one of those fallacies that tend to be more covertly communicated in many cases, in that eye rolls, head shaking, and outright laughter tend to communicate that such an argument has been made rather than the outright statement.
A typical example of this from a recent debate I got myself into:
BLL: Well, in terms of probability, it’s just as likely that a Christian may die, and find him or herself faced with Anubis, Thanatos or Richard Dawkin’s flying spaghetti monster as the Prince of peace.
Person I was debating: That’s absurd.
