The term ethics often describes the investigation and analysis of moral principles and dilemmas. Traditionally, philosophers and religious scholars have studied ethics. More recently, scholars from various disciplines have entered the field, creating new approaches to the study of ethics such as behavioral ethics and applied ethics.
The term ethics can also refer to rules or guidelines that establish what conduct is right and wrong for individuals and for groups. For example, codes of conduct express relevant ethical standards for professionals in many fields, such as medicine, law, journalism, and accounting.
Some philosophers make a distinction between ethics and morals. But many people use the terms ethics and morals interchangeably when talking about personal beliefs, actions, or principles. For example, it’s common to say, “My ethics prevent me from cheating.” It’s also common to use morals in this sentence instead.
So, whether we use the term ethics to refer to personal beliefs, or rules of conduct, or the study of moral philosophy, ethics provides a framework for understanding and interpreting right and wrong in society.
