A principle of paternalism must be able to answer three questions. Who are the persons who are the proper object of paternalism? Which actions should we prevent persons from doing or induce them to perform? What should our goals be when acting paternalistically toward these persons? A satisfactory principle will also be reasonably precise in distinguishing appropriate from inappropriate instances of paternalism, and it will be comprehensive, speaking to most potential cases, including suicide. My purpose is not to reach a (...) conclusion about the acceptability of paternalistic restrictions on suicide. Rather, because such a conclusion will follow from the way in which a principle of paternalism is formulated, I want to examine several liberal attempts at formulation and the theoretical background underlying these attempts.
