How shall a man meet different moral situations? What line of conduct should he follow on different occasions? How shall he resolve each conflict of duty? These are questions which he alone can best solve. It is his own conscience which is at stake. However, this does not mean that he should disdain whatever sources of guidance may be available to him. It means that what he has to do in particular circumstances at his particular stage of evolution is not necessarily what other men would have to do.
