Fire
Explanation
This comic satirizes the logical absurdity of historical witch trials by having the accusers walk through their own reasoning to its inevitable, self-defeating conclusion.
In the first panel, a Puritan man tells a woman, "Prove you are not a witch." She replies, "I predict you will not set me on fire." This is a clever gambit: if they don't burn her, her prediction comes true, seemingly proving she can see the future -- a witch-like power. If they do burn her, her prediction was wrong, which would suggest she's not a witch.
The accusers discuss this paradox. They reason: if they don't set her on fire, then her prediction was correct, which would indicate she has supernatural foresight, meaning she is a witch, which means they need to set her on fire. But if she is a witch, her prediction that they wouldn't set her on fire would be wrong -- and if she's wrong, maybe she's an innocent (non-magical) person after all.
They resolve this circular reasoning by concluding that since she's a witch, her prediction must be wrong, so they will set her on fire. In the final panel, the woman stands engulfed in flames while one of the men says, "So glad there's a policy in place." This darkly comic ending highlights how the witch trial system was designed to guarantee guilt regardless of evidence, and how bureaucratic confidence can persist even when the underlying logic is completely broken. The phrase "policy in place" satirizes institutional comfort with unjust procedures.
