In contrast, my aim is to develop a theory of objective morality that fits well with a general
naturalistic, evidence-based approach and with particular findings about how brains think. Many
philosophers would view this as a hopeless task, because of Hume's famous injunction that you
cannot derive an ought from an is. I do not claim to have produced such a derivation, as Hume was
undoubtedly right that there are no sound deductive arguments that can take you from empirical facts
about the world to the acceptance of particular or general moral judgments.
