Abstract

Singer, Peter As someone who has been involved in contemporary ethics and political philosophy, what public ethics suggests to me is a concept that was put forward by the late twentieth-century American philosopher John Rawls. He wrote a famous book, A Theory of Justice, in which he talked about what he called 'public reason'. His idea is that in a pluralist society that does not have any established religion, when citizens argue about ethical issues they should do so in a manner that can be accepted by other people in society, and doesn't presuppose beliefs that only a segment of that society is going to be able to endorse.
