This is an interesting way of thinking about it, but I’ll note: Kant absolutely believes that humans are special. His moral philosophy is grounded in the concept of a self-legislating agent, which in turn is more or less coextensive with a human being. Self-legislating agents are, in Kant’s view, the only type of thing that moral “oughts” impinge on. (That doesn’t mean he’s right, but I think it’s worthwhile to point out in an exegetical context.)
