Moral philosophy, also known as ethics, is the study of what is right and wrong, good and bad. It explores questions about how people should act and what values they should hold. Philosophers in this field analyze different moral theories, such as utilitarianism, which focuses on the greatest good for the greatest number, and deontology, which emphasizes duties and rules. This branch of philosophy also examines concepts like justice, virtue, and moral responsibility. By understanding these ideas, individuals can better navigate ethical dilemmas in personal and societal contexts, helping to shape their beliefs and actions in everyday life.
