ABSTRACT
Static economics takes account only of the universal characteristics over time and space, of the common features of men and women, of what makes them homogeneous; but empirical evidence puts an economist before an everchanging society, a society in which differences in characteristics increase in importance (in comparison to uniformity of characteristics). It would be ‘scientifically wrong (since economics is a science of facts)’ not to take into account dynamic economics, Sella maintains, ‘since it is not the facts which are missing, it is instead their processing which is missing’ (Sella 1915: x).
