It is specially focused in the analysis of complex social systems and the process of abstraction, construction and understanding of the social-territorial and spatial field of study. The text is oriented in two main parts by contextualizing the complex thinking as fundamental base for analyzing the systems and then, it discourses on features like causality, structure, evolution and dimension. Finally, it configures a practical dialogue for its application in the understanding of the territory.
