What philosophies and concepts shape personal ethical standards?

"Ethics is a set of moral standards for judging whether something is right or wrong. A utilitarianism approach to setting personal ethical standards focuses on the consequences of an action taken by a person or organization. According to this approach, people should act so as to generate the greatest good for the greatest number. A philosophy in which a person will follow his or her obligations to an individual or society because upholding one's duty is what is ethically correct is called deontology. Every human is entitled to certain rights such as freedom and the pursuit of happiness. Another approach to ethical decision-making is justice, or what is fair according to accepted standards. An ethical issue is a situation where a person must choose from a set of actions that may be ethical or unethical."
