Abstract

In this paper, I defend the following thesis: The Problem of Symmetrical Attackers does not falsify forfeiture theory. The theory asserts that except in the case where violence is necessary to avoid a catastrophe, only those who forfeit their rights are liable for defensive violence. The problem focuses on the following sort of case. Symmetrical Attacker Case Al and Bob are doppelgangers. They both mistakenly but justifiably think that the other is about to attack him. They both respond with violence that is necessary and that they think is necessary to prevent the attack. The problem is that one person forfeit his right if and only if the second does not and that it appears to be impossible for both or neither to forfeit. I argue that the forfeiture theory is not falsified by this problem because the problem is equally damaging to every plausible theory of permissible defensive violence.
