Brandom’s Account of Reasoning
Nonmonotonic, But Does Not Allow Entitlement Recovery
In most everyday instances of reasoning, reasoners can gain, lose, and reacquire entitlement to (or justification for) a possible commitment (or belief) as a result of their consecutively acquiring new commitments. For example, we might initially conclude that ‘Tweety can fly’ from ‘Tweety is a bird,’ but later have to reject this conclusion as a result of our coming to learn that Tweety is a penguin. We could, even later, reacquire entitlement to ‘Tweety can fly’ if we became committed (and presumably entitled) to the claim ‘Tweety has a jetpack.’ I will call this very common feature of reasoning entitlement recovery. In this paper I will argue that the types of inferential relations that are central to Brandom’s entire account of language and reasoning make entitlement recovery impossible. I will then briefly attempt to diagnose why this problem arises for Brandom and suggest how his account should be modified so that it will successfully allow entitlement recovery.
