Morality/Ethics: A system for making decisions about what you should value or how you should act.
A moral code is a way of selecting values in order to choose what kind of actions to take in life. Often the moral code consists of a moral standard of evaluation, which allows you to compare and contrast possible value to select which is better by that standard. A moral system may also include particular means deemed appropriate for pursuing those actions.
Morality and ethics are sometimes understood to be different. Sometimes morality is viewed as how you should act when you're alone, and ethics is how you should act when you're dealing with other people. Objectivism rejects this distinction because when you have a single method of making value judgments, it applies both when you're alone and when you're with other people. So Objectivism does not distinguish between morality and ethics. They are synonymous.
