Abstract. This paper reflects on Kantian exchanges between A. W. Moore and Sorin Baiasu. After briefly situating their exchange, I highlight Baiasu’s clarification regarding Kant’s distinction between knowledge and cognition. Although convincing, I suggest that Baiasu’s objections could be strengthened with further discussion of the notion of a thing in itself as a limiting concept, as well as emphasis on Moore’s use of ‘concern’, which might require further clarification. I conclude with broader reflections on what is at stake: not just armchair knowledge, but the coherence and relevance of Kant’s practical philosophy under the assumption of its dependence on transcendental idealism.
Key words: Kant, limits, metaphilosophy, transcendental illusion, armchair knowledge.
