Is there a solid foundation for the ethical concept of the good? Danish-Jewish thinker Andreas Simonsen explores this "ancient all-important question initially debated by the Sophists, Socrates and Plato" using an ancient technique - the dialogue form. Three separate conversations, three different interlocutors, three different worldviews: skeptical, rationalist and existentialist. This eclectic, thought-provoking work takes the reader on a fascinating journey through Western philosophy and scientific theory - to the author's unique adaptation of Niels Bohr's theory of "complementarity" to ethics.
