Contingent A Priori Truths as Original Declarations. Some Comments on Marco Ruffino

In his book Contingent A Priori Truths, Marco Ruffino proposes to understand Kripke’s examples of the contingent a priori in terms of utterances with a declarative illocutionary force. I think that Marco’s approach is very original and insightful, and he provides us with many detailed and thoughtful considerations in its support. Although I agree with the general picture, there are some aspects that remain a bit obscure to me, which will be the focus of this commentary, namely, the nature of the truth-makers of the allegedly (contingently) a priori true original declarations, and the transmission of a priori knowledge from baptizers to later uses.
