Is there any such thing as a single ethical system to which all human beings could conceivably subscribe?

The short answer is no; and most people, being tolerant, would probably agree with this answer. Yet most people, precisely in being tolerant, also subscribe to an idea of "human rights" which presupposes just such a universal ethics.

This basic question of ethics is similarly treacherous when approached on a higher technical level. Specialists have long recognized that Kant's categorical imperative is neither theoretically nor practically tenable. But efforts to revive and repair the Kantian project-including especially the monumental work of Jürgen Habermas-have all themselves been theoretically questionable, while developing a complexity that makes them impractical.

Must we then simply do without ethics in the sense of a universal ethical method?

By way of a close study of literary and philosophical texts, from Freud to Machiavelli, Benjamin Bennett shows why the failure of a universal or propositional ethics is indeed unavoidable. He uncovers a modern non-propositional ethics that cannot be grasped in a single theoretical move but can only be approached as a collection of instances of a modern ethical "we", three key examples of which Bennett explores in this book:

- The "we" of irony, whose speakers share a strictly preter-verbal knowledge which is concealed in their actual utterances

- The insistent exclusive "we" of a group that has neither its own physical locality nor even a clear intellectual identity, comparable to the "we" of Jews in the diaspora

- The "we" of feminism, a separate "we" from that embracing people who happen to have been born women.
