Kofer, Adam, and Beheimah: The Nature of Liability in Damages

The shiur analyzes Bava Kamma 4a, focusing on the Gemara (גמרא)'s difficulty in deriving the law of shor from adam. The Gemara presents a lo ro'i argument: we cannot learn shor from adam because adam pays kofer while shor does not, and conversely, we cannot learn adam from shor because adam is liable for arba devarim (pain, medical expenses, loss of work, embarrassment) while shor is not. The Rashba raises a fundamental question: typically, lo ro'i arguments in the Gemara focus on the inherent nature of the mazik (the damaging agent)—concepts like derech leilach lazek, koach acher me'ur bo, or sheken techilaso asuy le'nezek. Here, however, the pircha is purely halachic—adam pays arba devarim, shor pays kofer. This seems inconsistent with the standard structure of Gemara argumentation. Rabbi Zweig poses three fundamental questions that drive the shiur. First, how can a person be liable for damage caused by his property (shor) but not be liable for damage he causes directly with his own body? This seems illogical—surely personal liability should precede property liability. Second, the reverse problem: if a person is liable for what he does himself, why would the Gemara even consider learning that he should be liable for what his animal does? The liability for one's own actions doesn't automatically extend to one's property. Third, the Gemara says we cannot learn shor from adam because adam pays arba devarim. But suppose adam did not pay arba devarim—would we then be able to learn shor from adam? That makes no sense; the fact that I am liable for my own actions shouldn't teach me anything about liability for my animal's actions. These are fundamentally different categories of responsibility.
