Ethics and morals relate to “right” and “wrong” conduct. While they are sometimes used interchangeably, they are different: ethics refer to rules provided by an external source, e.g., codes of conduct in workplaces or principles in religions. Moral refer to an individual’s own principles regarding right and wrong.
Ethics or moral philosophy is a branch of philosophy that involves systematizing, defending, and recommending concepts of right and wrong conduct.
For a topic as subjective as morality, people sure have strong beliefs about what’s right and wrong. Yet even though morals can vary from person to person and culture to culture, many are universal, as they result from basic human emotions. We may think of moralizing as an intellectual exercise, but more frequently it’s an attempt to make sense of our gut instincts.
