The world today has many different moral codes, including many from religious sources. Some people claim their ethics are objective, provided by a divine being or the nature of reality, while many others believe morals and ethics are relative and subjective. Many systems clash with others, an increasing problem in today's global community.
Irrespective of where any system of ethics or morals comes from, are there any moral values or ethical codes which are universally agreed to by all humans, which can be found in all systems? If so, what are they?
