Why is Robert K. Merton important? Many treatments of his work focus only on particular components whereas, in fact, his work is far wider and can be summarised for each of his decades of life and work: 1920s (childhood), 1930s (anomie, science, unanticipated consequences), 1940s (housing studies, mass communications, structural-functional analysis, professions, focus groups), 1950s (reference groups), 1960s (ambivalence), and later decades (structural analysis, sociological semantics, cultural sociology). 

Merton particularly contributed to sociology during a period when several specialties were being set up and yet his work spans both general and specialist sociologies. He is recognised as the father of anomie/strain theory; focus groups; sociology of science; role-set theory; analytical sociology; structural-functional analysis; ambivalence studies; and sociological semantics. Many commentaries on sociology lament the ways it has slumped into a wide range of threads with not much of a core holding it together. Merton’s work always endeavoured to keep the multifarious threads of sociology together, and we might usefully learn some of the ways he accomplished this. 

Merton stood at the junction of many other crossroads in sociology and moreover endeavoured to create bridges between these, but more importantly to help launch research programmes along some of these paths. His work links classical and modern sociology; American and European sociology; theory and research; philosophy of social science and applied sociology; pure academic sociology and applied sociology; cognitive and social; social sciences and humanities; and social sciences and science. This book examines and relates to each other. Because Merton’s work spanned so many paths not many sociologists were alert to the overall architecture of his work and perhaps its visibility thereby waned. His viability is relatively less because of an astute writing style. Several of the programmes he helped launch have continued since: for example, media studies, criminology, and science studies.  

Merton had a major effect on the baby boomer generation of sociology who joined the ranks of sociology at a time of great expansion of university positions across many developed countries. While other generations since have been less exposed to his work reading the book will provide many valuable insights.
