 According to a different interpretation of Kant, another cannot share the end an agent pursues in using him in some way if how the agent behaves “prevents [the other] from choosing whether to contribute to the realization of that end or not” (Korsgaard 1996: 139). The lender in our example cannot share the borrower’s end of getting money without ever repaying it; for the borrower’s false promise obscures his end and thus prevents the lender from choosing whether to contribute to it.
