The pattern in The social logic of space (1984) and in A pattern language (1977)

This theoretical essay has in the pattern its anchorage. What we highlight here is the debate over pattern in the works of Hillier and Hanson and Alexander, Ishikawa and Silverstein. By pointing out the understandings and differences about the role of the pattern in both works, we seek to contribute to the debates about languages, logic and abstraction both in cognitive processes, also called epistemological, and in the processes of legitimization of certain spatial-social knowledge in different contexts. What stands out from the two works is the way they are defined and the standard treatment. Although the first deals with syntax and the second with language, both are undoubtedly spatial readings of certain levels and dimensions of what guides and structures urban space. Although in a different way, use the pattern as a theoretical tool for analytical practice and for design purposes. The differences between the approaches are mentioned in the preface to The Social Logic of Space. Here we explore some evidence of the relationship between the two, in view of the challenges of dealing with the complexity of the contemporary socio-spatial issue in terms of and incorporating sustainable urban, and economic social issues – in global North and South, and in decolonial terms. What is proposed here is a critical analysis of the roles of the spatial pattern of both works, given the frameworks referenced in the works studied and in other references that deal with and advance on the theme and that have been part of our field and objects of study.
