One of the things that distinguishes humankind from every other species on earth is that we have a moral dimension. A moral law seems to be programmed into our psychological software and our awareness of it is triggered by the conscience, a mysterious monitor that pokes its nose into every nook and cranny of our lives.
Why should this be the case? does our moral sense come from nature, is it nothing more than a cultural phenomenon, or is personal preference the deciding factor? Have we any right to question another person s moral choices? Are there consistent guidelines for deciding whether something is good or evil, right or wrong, just or unjust?
Beyond these questions lies an even greater one: can we ever find a solid and coherent basis for morality unless our world view has God at the very centre of it?
