During the mid-1980s, Latin American colonial studies came to be dominated by the various ‘post’ movements—post-structuralism, post-modernism, post-Marxism—characterized by their promotion of discursivity as the ultimate horizon of sociality. This volume confronts discourse theory and examples of its colonial application with an alternative Althusserian problematic that foregrounds modes of production and class struggle, to which end it further promotes a view of colonial societies as split, not along a horizontal, geographic axis that offsets the New World against Europe, but vertically through the opposition between dominant tributary/feudal formations and their emergent capitalist equivalent. Its fundamental claim is that the radical-sounding rhetoric of the various ‘post’ movements, far from energizing the politics of resistance to the forces of imperialism, actually greases the mechanisms of finance capital.

En los sistemas complejos, cada problema, debe ser tratado en detalle partiendo de cero, y poco o nada de lo aprendido al resolver un sistema anterior nos puede ayudar a entender uno nuevo. En los sistemas caóticos, de dos condiciones iniciales ligeramente distintas se obtienen, en el tiempo, dos soluciones dramáticamente diferentes. Casi todos los sistemas reales son termodinámicamente abiertos, mientras que los sistemas aislados, fuera de ser considerados sólo teóricamente, son raros en la naturaleza. La naturaleza sigue el principio del orden a partir del caos o desorden, contrario diametralmente al que estipula la física clásica, que va del orden al desorden, La visión del mundo de los sistemas complejos exige una nueva forma de hacer ciencia. La complejidad, un travestista del enfoque ético sistémico, intenta dar solución a problemas considerados como críticos, y crítico es todo lo que desconocemos, y para acceder a lo desconocido, según las reglas actuales, se reclama un episentido.
