Relating to a moral theory that focuses on rules and duties rather than the consequences of actions.
The philosopher discussed a deontological approach to ethics, emphasizing the importance of following moral rules.
Deontological is formed from "deon" (from Greek "deon", meaning duty) and "-logical" (from Greek "logia", meaning study or science). The term refers to the study of duty or moral obligation in ethics.
Think of 'duty' ('deon') and the study of it ('-logical') to remember that deontological relates to the ethics of duty.
