This document discusses the concept of justice. It provides definitions of justice from philosophers like Plato, Aristotle, and St. Thomas Aquinas. Justice involves fairness, giving each person their due, and upholding the rights of others. Something becomes someone's due through natural law based on human nature/relationships or positive law like agreements/legislation. Not all laws are just as they may contradict natural law or not promote the common good. The practice of justice is important for media practitioners in their treatment of audiences, sources, colleagues, and employers.
