The first law of ecology is that everything is related to everything else.Law is a system of rules that are created and enforced through social or governmental institutions to regulate behavior. Law as a system helps regulate and ensure that a community show respect, and equality amongst themselves.The history of law links closely to the development of civilization. Ancient Egyptian law, dating as far back as 3000 BC, contained a civil code that was probably broken into twelve books.

It was based on the concept of Ma’at, characterised by tradition, rhetorical speech, social equality and impartiality. By the 22nd century BC, the ancient Sumerian ruler Ur-Nammu had formulated the first law code, which consisted of casuistic statements («if … then …»). Around 1760 BC, King Hammurabi further developed Babylonian law, by codifying and inscribing it in stone. Hammurabi placed several copies of his law code throughout the kingdom of Babylon as stelae, for the entire public to see; this became known as the Codex Hammurabi.

The most intact copy of these stelae was discovered in the 19th century by British Assyriologists, and has since been fully transliterated and translated into various languages, including English, Italian, German, and French.

The law of harvest is to reap more than you sow. Sow an act, and you reap a habit. Sow a habit and you reap a character. Sow a character and you reap a destiny.Law provides a rich source of scholarly inquiry into legal history, philosophy, economic analysis and sociology. Law also raises important and complex issues concerning equality, fairness, and justice.

There is an old saying that ‘all are equal before the law’, although Jonathan Swift argued that ‘Laws are like cobwebs, which may catch small flies, but let wasps and hornets break through.’ In 1894, the author Anatole France said sarcastically,Numerous definitions of law have been put forward over the centuries. The Third New International Dictionary from Merriam-Webster defines law as:

«Law is a binding custom or practice of a community; a rule or mode of conduct or action that is prescribed or formally recognized as binding by a supreme controlling authority or is made obligatory by a sanction (as an edict, decree, rescript, order, ordinance, statute, resolution, rule, judicial decision, or usage) made, recognized, or enforced by the controlling authority.»

If you must break the law, do it to seize power: in all other cases observe it.The Old Testament dates back to 1280 BC and takes the form of moral imperatives as recommendations for a good society. The small Greek city-state, ancient Athens, from about the 8th century BC was the first society to be based on broad inclusion of its citizenry, excluding women and the slave class.

However, Athens had no legal science or single word for «law», relying instead on the three-way distinction between divine law (thémis), human decree (nomos) and custom (díkē). Yet Ancient Greek law contained major constitutional[disambiguation needed] innovations in the development of democracy.Roman law was heavily influenced by Greek philosophy, but its detailed rules were developed by professional jurists and were highly sophisticated.

Over the centuries between the rise and decline of the Roman Empire, law was adapted to cope with the changing social situations and underwent major codification under Theodosius II and Justinian I.Although codes were replaced by custom and case law during the Dark Ages, Roman law was rediscovered around the 11th century when medieval legal scholars began to research Roman codes and adapt their concepts.

Latin legal maxims (called brocards) were compiled for guidance. In medieval England, royal courts developed a body of precedent which later became the common law. A Europe-wide Law Merchant was formed so that merchants could trade with common standards of practice rather than with the many splintered facets of local laws.

Law and order exist for the purpose of establishing justice and when they fail in this purpose they become the dangerously structured dams that block the flow of social progress.The philosophy of law is commonly known as jurisprudence. Normative jurisprudence asks «what should law be?», while analytic jurisprudence asks «what is law?» John Austin’s utilitarian answer was that law is «commands, backed by threat of sanctions, from a sovereign, to whom people have a habit of obedience».

Natural lawyers on the other side, such as Jean-Jacques Rousseau, argue that law reflects essentially moral and unchangeable laws of nature. The concept of «natural law» emerged in ancient Greek philosophy concurrently and in connection with the notion of justice, and re-entered the mainstream of Western culture through the writings of Thomas Aquinas, notably his Treatise on Law.

Hugo Grotius, the founder of a purely rationalistic system of natural law, argued that law arises from both a social impulse—as Aristotle had indicated—and reason.Immanuel Kant believed a moral imperative requires laws «be chosen as though they should hold as universal laws of nature». Jeremy Bentham and his student Austin, following David Hume, believed that this conflated the «is» and what «ought to be» problem. Bentham and Austin argued for law’s positivism; that real law is entirely separate from «morality».Kant was also criticised by Friedrich Nietzsche, who rejected the principle of equality, and believed that law emanates from the will to power, and cannot be labelled as «moral» or «immoral».
