This is the sixth Big Question, launched by the John Templeton Foundation, along with thirteen views on it presented by several important scholars. Just to cite a few: Stanley Fish, Christine M. Korsgaard, Joshua D. Greene, Jonathan Sacks, Jean Bethke Elshtain, and Antonio Damasio. The material can be found here.
What is (or should be) the role of reason in discerning the morally right from the morally wrong? And from what perspective should we address this problem? Some will argue that we have to search for the answer through philosophical inquiry. Others will endorse a more empirical approach, believing in the advancements of the neurosciences as a source for knowledge about moral behavior.
Both views, and the ones in between, are quite appealing – especially when presented by such brilliant minds. So it is really worth taking a look at what they have to say!
