This article proposes a re-visioning of sociology and of its relationship to the late-modern world it inhabits. I first problematize the claim that sociology is a discipline in any ordinary sense of the term, indeed, that social science can be reasonably cleaved into "disciplines" on the model of natural science. I then explore the thesis that sociology and kindred pursuits have been constituted as fields. Finally, I argue that among the fields of social scientific inquiry, the sociological terrain is of great import, as a nexus whose permeability, dense connectivity to other fields and critical transdisciplinarity are prime assets. By implication, the remedy for centrifugal tendencies that worry some sociologists is greater clarity on matters of social ontology and, on that basis, a coherent methodology (critical realism) that can strengthen sociology's capacity to understand our troubled world and to defend and enrich democratic practices that may portend a better future. © 2013 Canadian Sociological Association/La Société canadienne de sociologie.
