An article is production / the circulation / a changed thing fortune in economic activities. The rights such as service or the securities such as a legal advice or the mail carrier, information are included in an article other than the things such as an apple or clothes as a concrete example. When I put the principal objective to the thing fortune to sell, I am called the quotient materials. In Marxian economics, the article is a fortune / service aimed for personal exchange. In the first place, not an object of the exchange, a fortune / the service used by producer oneself does not give it off with an article, and the existence called the article is formed in exchange relations. In addition, the article has "the value" that is a property to have "the usefulness" that is a property to let human needs fill up and every article and commutativity. This value is decided for the social public by the working hours when it is necessary, and the value has a property to deteriorate if productivity rises.
