 One of Singer’s first critics, Daniel Kading (1959), defends rights without release. Kading says we only have rights against people with whom we have struck some kind of agreement – like a promise or contract – and sometimes, these people aren’t around to release us. They might, for example, be dead. There is no hope of release in such a scenario, and yet the right remains. But even if this correct, it won’t do anything to establish duties to oneself (as Kading seems to admit). There is something fishy about the idea of “agreements” with oneself, and, as Muñoz (2020, 694) points out, the deathbed promise has no one-person analogue. (See Singer 1963, 133–35, for further objections.)
