Method, Economics, Evolution

Common to the two founders of Modern Philosophy, Descartes and Bacon, is the employment of Method, of which Rationalism and Empiricism are two types.  But, as the focus of Modern Philosophy shifts to Epistemology, i. e. to immediately given data, how the data is gotten gets obscured.  So, eventually, the presentations of the two main Economic doctrines of the era, Capitalism and Marxism, are haphazardly developed.  On the one hand, despite Smith's Empiricist orientation, the two cardinal features of his system--the Profit-motive and the Invisible Hand--are not grounded on Sense-Data.  On the other, while Marx-Engels subscribe to Dialectical Materialism, it is perhaps as a Method only when they call for Revolution, while committing in the German Ideology to an Empirical procedure that is far from rigorous.  Now, Darwinism is Empiricist, but the practice of Eugenics, which deliberately effects reproduction as a means to the generation of superior organisms, is thus Methodic Evolution.  Likewise, any means to Evolution, including, as has been previously discussed, an Economic system that promotes increase in Versatility, employs Evolution as a Method.
