Let us see the basics of economics. Their object is large enough – and this might be a good plus, but also the opposite, i.e. let us define what exactly is not economics. When the object seems to be too large, how serious can be this science in itself ? As for its method, this comprises at least two zones. The first one can be called the ‘essence’, the other part can be called the ‘borrowed’ one (see what belongs to mathematics and other sciences). This latter can be more easily identified, but concomitantly does not define economics, as essentially – if it did, this wouldn't be economics (a scientific entity in itself) any longer. But, back to the first part, as the essence, this stays difficult to be defined. Or, this is the very drama of a science.
