"Language as communication has three aspects or elements. There first what Karl Marx once called the language of real life, the element basic to the whole notion of language, its origins and development: that is, the relations people enter into with one another in the labour process, the links they necessarily establish among themselves in the act of a people, a community of human beings, producing wealth or means of life like food, clothing, houses. A human community really starts its historical being as a community of co-operation in production through the division of labour; the simplest is between man, woman and child within a household; the more complex divisions are between branches of production such as those who are sole hunters, sole gatherers of fruits or sole workers in metal. Then there are the most complex divisions such as those in modern factories where a single product, say a shirt or a shoe, is the result of many hands and minds. Production is co-operation, is communication, is language, is expression of a relation between human beings and it is specifically human."
