 Kant claimed that all of these CI formulas were equivalent. Unfortunately, he does not say in what sense. What he says is that these “are basically only so many formulations of precisely the same law, each one of them by itself uniting the other two within it,” and that the differences between them are “more subjectively than objectively practical” in the sense that each aims “to bring an Idea of reason closer to intuition (by means of a certain analogy) and thus nearer to feeling” (G 4:435). He also says that one formula “follows from” another (G 4:431), and that the concept foundational to one formula “leads to a closely connected” concept at the basis of another formula (G 4:433). Thus, his claim that the formulations are equivalent could be interpreted in a number of ways.
