This volume includes fourteen essays by eminent sociologists in memory of Ramkrishna Mukherjee (1919–2017), the last of the founding architects of sociology in India. It also includes two interviews with Ramkrishna Mukherjee by senior sociologists. The essays cover a variety of themes and topics close to the works of Ramkrishna Mukherjee: the idea of unitary social science, methodology of social research, the question of facts and values, rural society and social change, social mobility, family and gender, and nationalism. In the two interviews included here Mukherjee clarifies his intellectual trajectory as well as issues of methodology and methods in social research. Overall, this volume endorses his emphasis on the need for social researchers to transcend the ‘what’ and ‘how’ to ‘why’ in the pursuit of sociological knowledge. The volume is a valuable addition to the history of sociology in India. Students of sociology and other social sciences will find it useful as a book of substantive readings on social dynamics; those researching the social world will find in it a useful guide to issues in designing and execution of social research projects.
