Social theory has a discovered and discoverable past and a complex, contested, dynamic, and anxious present. All of these adjectives save the last one-anxious-are reflected in various ways and with differing emphases throughout this handbook. I will say something about "anxious" below, but before doing so will offer a rationale for producing this multi-authored, two-volume overview reflecting the diversity of theory work in sociology and offering a sense of both where the discipline has come and where it is today. There (...) is no univocal answer to the question, What does social theory mean? Since the institutionalization of sociology in the academy and its development of subfields, theory has found a place in the overall educational structure of the discipline, in a manner akin to the way that methodology has. That is to say, both theory and methodology have been viewed in some fashion as essential to sociological inquiry, and thus relevant to all of the substantive subfields within it. At the same time, it became clear early on that consensus regarding the meaning of theory has proven elusive. As World War II came to an end and the rapid expansion in higher education was about to commence, Robert K. Merton (1945), the protégé of Talcott Parsons, claimed that six types of analysis had come to be described as sociological theory. Over six decades later, Gabriel Abend (2008) identified seven distinct though sometimes overlapping meanings attributed to theory-a figure that Omar Lizardo (2014) thinks is at the lower end of the actual number of different meanings.
