Final answer:
Theoretical Ethics is a branch of Philosophy that involves the study of moral reasoning, foundational questions, and applying ethical principles to real-life issues.
Step-by-step explanation:
Metaethics, normative ethics, and applied ethics are the three main areas of ethics, each distinguished by a different level of inquiry and analysis. Metaethics focuses on moral reasoning and foundational questions that explore the assumptions related to our moral beliefs and practice. It explores where moral values originate, what it means to say something is right or good, whether there are any objective moral facts, whether morality is relative, and the psychological basis for moral practices and values. Normative ethics, on the other hand, focuses on moral behavior and attempts to establish criteria or principles for guiding correct behavior. It offers systematized accounts of morality and provides standards and norms of right conduct. Finally, applied ethics applies moral norms and principles to controversial issues to determine the rightness of specific actions.
