In Extended Rationality: A Hinge Epistemology , Annalisa Coliva aims to by-pass traditional sceptical challenges to the possibility of knowledge by arguing that all thinking and knowing ultimately rely on hinge assumptions which are immune from doubt because of their foundational role in the very framework that makes knowledge and rational thought possible. In defending her position Coliva also rejects the relativist challenge that there could be incompatible but equally plausible systems of justification relying on alternative hinges or assumptions. In this response to Coliva, I argue that even if we accept that we need to rely on some core assumptions in order to get the process of rational thought going, the question of the uniqueness of these assumptions remains open. I maintain that Coliva’s two argumentative strategies against the possibility of relativism, one based on empirical considerations and a second relying on considerations from logic do not guarantee the uniqueness of hinge assumptions and the possibility of at least a moderate form of relativism looms large.

评论 Annalisa Coliva，扩展理性：铰链认识论

在扩展理性：铰链认识论中，安娜丽莎·科利瓦 (Annalisa Coliva) 旨在绕过对知识可能性的传统怀疑挑战，她认为所有的思考和认识最终都依赖于铰链假设，而铰链假设是免于怀疑的，因为它们在框架中的基础作用使知识和理性思考成为可能。在捍卫她的立场时，Coliva 还拒绝了相对主义的挑战，即可能存在不相容但同样合理的辩护系统，依赖于替代铰链或假设。在对 Coliva 的回应中，我认为即使我们承认我们需要依赖一些核心假设才能使理性思考的过程继续下去，但这些假设的唯一性问题仍然悬而未决。
