Justice, in its broadest context, includes both the attainment of that which is just and the philosophical discussion of that which is just. The concept of justice is based on numerous fields, and many differing viewpoints and perspectives including the concepts of moral correctness based on ethics, rationality, law, religion, equity, and fairness. Often, the general discussion of justice is divided into the realm of social justice as found in philosophy, theology and religion, and, procedural justice as found in the study and application of the law.
