To accept a notion of rational suicide, as many contemporary bioethicists now urge, first makes possible certain kinds of manipulation into suicide which do not occur in suicide-impermissive societies. This paper describes the two principal mechanisms by which an individual can be manipulated into choosing to kill himself or herself, though that individual would not have done so otherwise, and identifies circumstantial and ideological changes in contemporary society which may be associated with such manipulation now and in the future. However, (...) the author holds that this prospect is not grounds for rejecting the notion of rational suicide;it must be accepted on other moral grounds, but with a clear view of the risks it will bring.
