 We now have at least three accounts of how principles might figure in a reliable strategy for acting well. But why think that principles do or must figure in the best strategies for moral action? Or, taking the other side, why think that principles are useless or even counterproductive? If one could establish or assume a specific generalist account of moral standards, this would open up many lines of argument for guidance by principle. The same would be true if one could establish particularism about standards. However, such assumptions are not dialectically available in the generalism/particularism debate. Accordingly, we here focus on arguments that are largely neutral about the content of the moral domain and whether it is “principled”.
