Response to Block on Abortion, Round Three

"Block (2011) has offered a second round of counterarguments to my criticisms (Wisniewski 2010a, 2010b) of the claim that his theory of evictionism is compatible with libertarianism. In this paper I attempt to demonstrate that my critique still stands. In particular, I focus on analyzing the argumentative weight of such issues mentioned in Block’s latest response as, among others, the distinction between proper ex post punishment and proper ex ante defense, the question of whether my causal analyses of trespass imply a commitment to positive obligations, Rothbard’s distinction between contracts and premises, the supposed irrelevance of the principle of pacta sunt servanda in the context of abortion, and the extent to which custom can qualify the ambit of applicability of the non-aggression principle."
