The book begins with an overview of metaethics and a rejection of the
metaethics/normative ethics distinction, and discusses the strengths and
limitations of the popular idea that morality is a set of rules for how
we treat one another. It then explains subjectivist, intersubjectivist,
and objectivist accounts of the truth conditions of moral statements, .
It considers Divine Command Theory and Kant's categorical imperatives,
in his Groundwork of the Metaphysic of Morals, along with David Hume's
arguments in A Treatise of Human Nature and Enquiry Concerning the
Principals of Morals, and A. J. Ayer's 'emotivism'. The Final chapter
sketches a naturalist objectivism and suggests that the obstacles to its
acceptance are typically grounded on spurious asymmetries between ethics
and other disciplines. The author is tutor in philosophy at the
University of Edinburgh
