One way of describing its development is to see its starting point in the eighteenth-century notion that human beings are endowed with a moral sense, an intuitive feeling for what is right and wrong. The original point of this doctrine was to combat a rival view, that knowing right and wrong was a matter of calculating consequences, in particular, those concerned with divine reward and punishment. The idea was that understanding right and wrong was not a matter of dry calculation, but was anchored in our feelings. Morality has, in a sense, a voice within.
