I would definitely have to agree with this statement. I think there are numerous historical and literary examples which show the truth of this fact. When we think about it, social order is something that is so important to us as it gives us all a system of rules and behaviour that we know we must all abide by. Failure to abide to it will result in clearly laid out punishments that are accepted by all and administered by an impersonal body in the name of justice. However, if you suddenly take away that social order for whatever reason, then unfortunately people are free to commit crimes because of the lack of consequences that they will face. The truth is that as much as we like to think ourselves as law abiding and moral creatures, unfortunately without rules and regulations so many humans show that they are essentially lawless and thus need to be in a lawful social order to be kept on the straight and narrow.
I remember reading about the aftermath of the Japanese disaster recently and the way that a minority of Japanese saw the chaos brought about by the natural disaster as an excellent opportunity to loot their neighbours and steal from them. Clearly this is something that they would never normally do if lawful social order was in place, but because of the breakdown of this they were able to. Texts such as Lord of the Flies and The Heart of Darkness likewise show that when we are placed in an arena without a lawful social order, mankind will descend into a state of mindless anarchy. Unfortunately, delve deep within us and you find that we are lawless savages.
