Justice As Desert by Louis Pojman.
Justice is a constant and perpetual will to give every man his due. The principles of law are these: to live virtuously, not to harm others, to give his due to everyone. Jurisprudence is the knowledge of divine and human things, the science of the just and the unjust. Law is the art of goodness and justice. By virtue of this [lawyers] may be called priests, for we cherish justice and profess knowledge of goodness and equity, separating right from wrong and legal from the illegal. (Ulpian in the Digest of the Roman book of law Corpus Juris. ca 200 AD)
