The difference between ethics and morals can seem somewhat arbitrary to many, but there is a basic, albeit subtle, difference. Morals define personal character, while ethics stress a social system in which those morals are applied. In other words, ethics point to standards or codes of behavior expected by the group to which the individual belongs. This could be national ethics, social ethics, company ethics, professional ethics, or even family ethics. So while a person’s moral code is usually unchanging, the ethics he or she practices can be other-dependent.
