Natural Law Theory: Evolving over the Centuries

The natural law philosophy, over centuries has been the face of justice and peace for the people. It has been developed against tyranny, absolutism and misrule and over time had a hand in liberating people and bringing about a change in the society.
An ongoing debate is whether it is just a theory or if it actually has any practical basis? Philosophers and thinkers believe that natural law has inspired people over the time. People have fought against the absolutism in France, Germany, Prussia, England, Russia etc. Using the liberal and individualistic laws, derived out of Natural Law. Blackstone observed that “the natural law being co-existent with mankind and emanating from God himself, is superior to all other laws. It is binding over all the globe in all countries…”
Natural Law philosophers go all the way back to 5th century, in Greece, where they believed it is something beyond mankind. In ancient societies it was believed that natural law has divine origin. The Greek philosophers believed it is based on reason and therefore it has a universal force which binds men beyond race or nationality. Cicero supported Natural Law and believed, “It is the creation of reason of intelligent man who stands in the highest creation by virtue of his faculty of reasoning.”
Over the time, many a thinkers have given it different meaning, but it had been distinguished from man-made laws. Natural law is believed to be the guiding principle behind all laws, as it is indispensable in creating rules and laws for human beings. This can be seen from its evolutionary character how it survived with its basic principle intact all those years. The only time it took a dip was in the 19th century where the Positivism theory, rose, but nonetheless it was back in the 20th century, returning to being the core of most of the law of the time.
