Retracing Wolfgang Streeck's scientific path, the following interview illustrates some key nodes in critical political economy to finally focus on the general state of contemporary sociology. As a specific stream of a scientific niche, critical political economy addresses indeed relevant questions to both empirical research and sociological theory. Rooted in the so called "critical theory", Streeck explains how every analysis of the institutional frameworks of contemporary capitalism cannot be detached from a historically grounded and a theoretically informed macro-sociological research. This peculiar articulation allows moreover to investigate the relations between social sciences research on diversity of capitalism and its political salience for democratic capitalism. Moving from personal experiences until general assessments on the state of the discipline, the interview finally aims to shed light on the practice of sociology as a Weberian Beruf - a professional and intellectual craft - and to elucidate its possibilities and limitations in the working and living conditions of contemporary academia.
