If one has a right merely in virtue of being a person, she cannot lose that right as long as she remained a person – or so I argue. After sketching out what I mean by “natural rights,” “inalienable rights,” and “nonforfeitable rights,” I give some reasons to think any instance of the first would also have to be an instance of the latter two. I then respond to critiques of inalienability by A. John Simmons and Andrew Jason Cohen. After which, I apply the argument given for why natural rights would have to be inalienable as a reason to think they would also have to be nonforfeitable. Then I respond to the idea that the nonforfeitability of natural rights would conflict with self-defense by outlining an alternate account of self-defense. In closing, I consider some potential implications of the inalienability and nonforfeitability of natural rights, should such natural rights exist.
