"To conclude, I judge positively Seide's work. In a simple and original way, he reconstructs with precision one of Kant's most important theoretical routes, enjoying a living and growing attention in the contemporary scenario. Thanks to the exploration of several texts in which this path takes place, and to the constant relationship with the secondary literature, Seide indeed puts forth a work of strong interest and relevance."
