Foundations, Frameworks, Lenses: The Role of Theories in Bioethics
I explore the implications of the foundation metaphor for understanding the role of moral theories in ethics and bioethics and argue that its disadvantages outweigh its advantages I then consider two other metaphors that might be used instead those of frameworks and lenses I propose that the metaphor of lenses is most promising in providing methodological guidance for drawing on moral theories when deliberating about bioethical problems
