Normative theory deals with evaluating what is right and wrong, desirable or undesirable in society. Most sociologists believe sociology should be value-free and avoid explicit value judgements. Normative statements make claims about how things should be rather than descriptive claims about what is. In philosophy, normative ethics examines moral principles and virtues to determine right action and good character. The major normative ethical theories are utilitarianism, Kantianism, ethical intuitionism, and virtue ethics.
