Taking Ethics Seriously

This book develops an intellectual framework for analyzing ethical dilemmas that is both grounded in theory and versatile enough to deal rigorously with real-world issues. It sees ethics as a necessary foundation for the social infrastructure that makes modern life possible, much as engineering is a foundation for physical infrastructure. It is not wedded to any particular ethical philosophy but draws from several traditions to construct a unified and principled approach to ethical reasoning. Rather than follow the common academic practice of seeking a reflective equilibrium of moral intuitions and principles, it builds on a few bedrock principles of rational thought that serve as criteria for valid argumentation. It develops the ideas from the ground up, without presupposing any background in ethics or philosophy. _x005F_x000D_ _x005F_x000D_ Epistemologically, the book views ethics as parallel to mathematics, in that it relies on generally accepted proof techniques to establish results. Whereas mathematics rests on such proof paradigms as mathematical induction and proof by contradiction, ethics can be seen as relying on proof by applying consistency tests, such as generalizability and respect for autonomy. Utilitarianism also plays a key role, but it is reconceived as a deontological criterion. This approach obviously requires that these criteria be formulated more rigorously than is normally the case. To accomplish this, the book begins with the classical idea that an action is distinguishable from mere behavior by virtue of its having a coherent rationale, where coherence requires passing certain consistency tests such as generalizability. An action is therefore inseparable from its rationale, and generalizability is defined in terms of consistency with the rationale. A utilitarian criterion receives a similar treatment with respect to a means-end rationale. Respect for autonomy is grounded in a carefully developed action theory that takes into account such concepts as
