Now we're rewriting the dictionary to conform to our worldview, eh?
There's no discussion of moral values? That's hysterical.
I just thought of a simple example of usage.
Some organizations produce their own Code of Ethics, and it's often highly regarded as a standard in the industry. They never call them a code of morality.
But the do sometimes call them simply a Code of Behavior. And since they are prescriptive and not to be argued with (handed down by a moral authority) they really should be called morals rather than ethics. They may be called a Code of Ethics to make people feel more comfortable with them. Some people would resent having to be told to obey a set of corporate moral prescriptions.
