One thing I enjoy about anthropology and the study of primitive communities is that they often illuminate modern concepts in a different, arguably even more basic, manner.
Today, we take law to denote a system of enumerated rules, originating in legislatures and enforced by courts. Consequently, we conclude that 'savage' societies are lawless, operating solely on the basis of "custom". Malinowski thinks we can do better than this.
Firstly, he debunks the popular notion of his time -- the supposition that savages unthinkingly submit to tradition and custom. In fact, they are very much like us: "whenever the native can evade his obligations without the loss of prestige, or without the prospective loss of gain, he does so, exactly as a civilized business man would do". Moreover, we are not so different from savages in our tendency to obey the law naturally and without coercion: "The fact is that no society can work in an efficient manner unless laws are obeyed 'willingly' and 'spontaneously'. The threat of coercion and the fear of punishment do not touch the average man, whether 'savage' or 'civilized'".
Then, Malinowski shows that even primitive communities organized themselves according to felt rights and obligations, without a body of explicitly "legal" texts. For example, the activity of fishing together on a canoe involves a series of definite obligations and duties, even for the savage. Reciprocity and vanity/ambition/publicity constitute two psychological mechanisms which supply obligations with binding force. "The real reason why all these economic obligations are normally kept, and kept very scrupulously, is that failure to comply places a man in an intolerable position, while slackness in fulfilment covers him with opprobrium. The man who would persistently disobey the rulings of law in his economic dealings would soon find himself outside the social and economic order -- and he is perfectly well aware of it."
To call savages lawless would therefore be a mistake. There's something in these societies that isn't just mere custom. This leads Malinowski to define law as "a class of obligatory rules ... provided with a purely social binding force", which he locates within the body of custom. "The rules of law stand out from the rest in that they are felt and regarded as the obligations of one person and the rightful claims of another ... Law dwells not in a special system of decrees ... [it] is the specific result of the configuration of obligations, which make it impossible for the native to shirk his responsibility without suffering for it in the future". The source of the law lies in our collective human imagination and its manifestation in our habits of life. According to Malinowski, its fundamental function, which differentiates it from other norms and customs, is to curb certain natural propensities, to hem in and control human instincts, in order to ensure a form of cooperation based on mutual concessions for a common end.
The next part of the book is concerned with primitive crime: what happens when the law is broken? Interestingly, just like in civilized societies, the ideal of the law does not correspond neatly with its application in real life. Systems of evasion exist which allow natives to circumvent the law. Public opinion is sometimes lenient. Moreover, native law is comprised of various independent systems which sometimes come into conflict. Noticeably, 'Father-love' has less legal importance than 'Mother-right' but is backed by strong personal feeling. A man's matrilineal nephew is his nearest kinsman and legal heir, while his own son is not regarded as a kinsman; however, in reality the father is more attached to his own son than to his nephew. This leads to non-legal practices by fathers to secure privileges for their sons, which over time came to be regarded as the most natural course by the community.
In the end, human cultural reality is "a seething mixture of conflicting principles". Malinowski concludes that "the true problem is not to study how human life submits to rules -- it simply does not; the real problem is how the rules become adapted to life."
