I want to clarify the relation between paternalism and the rights of self-determination by using medical disorder models. I have used one case to clarify the question of paternalism and the right of self-determination, using the case of real psychiatric patients: one in a self-reliant situation, one depending on others, and one chaotic situation. Paternalism and its limitations are examined for each situation. I conclude that ordinary people who are around psychiatric patients should take responsibility to help such persons.
