David Osterfeld on natural rights

Osterfeld is “on to something” in that he correctly points out what seems pretty obvious: natural rights have not been proven, and all attempts at proof so far have been invalid. He explains with a moderate amount of precision why this is so, and it may prove illuminating for readers who still think natural rights or natural law have been logically proven.

He then instead takes a emperico-logical approach to defending natural rights. Osterfeld is very pro-natural-rights, but he points out that the premises have not been proven. For example, he takes Rothbard’s syllogism:

Osterfeld says the premises 1 and 2 cannot be proven logically, but can be demonstrated emperically. He provides evidence for Premise 1, but falls short of making an emperical case to a scientific standard. Here is his support for Premise 1:

(1) does not violate any rules of logic as stated, and I trust the reader will note the error upon re-reading (if not, ask). Also, what if no one “owns” anyone? I can only be charitable and assume that Rothbard and Osterfeld might have meant, “‘No one being owned by anyone’ is a necessary means to sustain life.”

We’ll take Osterfeld’s word on this and assume Rothbard does explain the possibility of no one owning anyone.

By “private ownership,” Osterfeld obviously means “private property” - not “self-ownership.” Oops, no emperical defense for half of the major premise! (No, he doesn’t offer any additional support elsewhere.)

At best, Osterfeld’s entire defence of natural law boils down to: “There exists a strong historical case for respecting property rights, therefore everyone ought to respect property rights.” I agree that the historical case is strong, but that’s all Osterfeld has for us, and he only gives two sentences of historical evidence himself. The extra logical constructions add nothing to the historical case.
