One of the major disputes among those who work in applied ethics is whether or not there is a general and universal account of morality applicable both to the ethical issues in the professions and to various practical problems. Some philosophers believe that each of the professions or each field of activity develops an ethical code for itself and that there need be noclose relationship between (e.g.) business ethics,medical ethics, and environmental ethics. Others hold that the same moral system applies to all professions and fields. They claim that the appearance of different moral systems is simply due to certain problems being more salient for some professions and fields than for others.
