»Economics Revisited. On the Immanent Inaccuracy of Economics. To Adolph Wagner (1835-1917)«: Up to now economic theory is presented as mathematical economics with the scent of a precise and homogenous theory. But in the end we have fuzziness - in variables, data and supposed functional relations. Differences between the existing economies as well as rapid changes by all kinds of innovations and demografic impulses would perhaps require fuzzy mathematics, nearly without any possibilities of prediction. The reasons are outlined in the book in hand.
