Ancient Greek Legal System （1）

Legal System Development
In general, there are three stages that most legal systems progress through:
A Pre Legal Society
The only recognizable characteristic of a pre-legal society is that it has no established ways of dealing with disputes that arise in a society. A small society may remain in this stage for an extended period of time, but when the population density reaches a certain point there are too many people who don't know each other and a more formal system is needed.
A Proto Legal Society
A proto-legal society has rules as well as procedures for handling disputes. At this stage there is no distinction between rules (social standards, such as it's not nice to point), and laws (linking specific acts to specific consequences). This is a linking stage between the anarchistic pre-legal stage, and the more rigid legal stage.
A Legal Society
A legal society is one such as ours, which society has deemed certain acts so undesirable as to warrant a punishment. These societies have not given up their rules, but the rules do not necessarily result in punishment. Because the laws of a society link acts with punishment, normally a society must have developed a form of writing in order to enter this stage
