The history of "Natural Law" is extensive. Classical Greek Naturalism was the major doctrine until Christian Theologian Doctrine replaced it. As societies have moved away from the church "Natural Law" has been to some extent superseded by Positivism. We have been asked to critically evaluate these two schools of Jurisprudence.
Greek Naturalism
The classical Greek philosophers believed that natural law was a moral order, which was superior to human law and one that knows no bounds either in space or time. It decreed that people should be communal and that man-made regulations for communities were inferior to nature's laws.

Anything, which interfered with this, should be considered to be bad. He spoke about the relationship between fact and value, what is and what ought to be. Cicero in the first century BC perpetuated these views
