This document discusses codes of ethics and moral values. It explains that codes of ethics serve to protect the public interest, guide professionals, and inspire commitment to ethical standards. Codes help establish shared standards, support responsible conduct, and facilitate education and understanding. They also provide a basis for investigating unethical events. Codes contribute to a positive professional image and allow for self-regulation. However, codes also have limitations and can be subject to abuse if taken too seriously. The document compares the arguments of two philosophers, Michael Davis and Stephen Unger, regarding the role and purpose of professional codes of ethics. It also discusses how moral values, reasoning, and judgments vary across cultures and may change over time.
