This development leads into a contradictory situation both on the practical and the theoretical level: because the process of rationalization precludes the grasp of any kind of totality, it cannot ever succeed in making the whole of society subject to rational calculation for it necessarily must exclude all irrational, qualitative dimensions from such calculation. As Lukács argues, the inability of economic rationality to integrate qualitative features (e.g., of consumption) into a formal system not only explains the economic crises of capitalism but is also reflected in the inability of economic science to explain the movements of the economy (1923a: 105–107). The same holds true for a formalist model of law, which cannot theoretically acknowledge the interdependence of its principles with their social content and therefore must treat this content as an extra-legal, irrational foundation (1923a: 107–110).
