Review Of Ram Ramaswamy’s ‘D.D. Kosambi: One Life, Many Worlds’

Today, the word ‘polymath’ is often deployed in a mundane manner. In the mid-20th century, encountering Damodar Dharmananda Kosambi (1907–66) was to experience a profound intellectual shock. He had published foundational papers on differential geometry and formulated a vital genetic mapping concept known as the ‘Kosambi distance’. He also laid the groundwork for numismatics by statistically analysing ancient punch-marked coins and, with his multifaceted brilliance, revolutionised the writing of Indian history using a Marxist lens.

As a physicist and former Jawaharlal Nehru University professor, Ram Ramaswamy observes in his book D.D. Kosambi: One Life, Many Worlds that Kosambi remains a figure more frequently cited than truly understood. Kosambi  is highly praised for his historical approach, but often scrubbed of his complex scientific and personal details. Ramaswamy’s book presents Kosambi as a living, breathing portrait of a brilliant yet deeply principled giant who was ahead of his time. Ramaswamy has previously edited Kosambi’s mathematical papers and his lesser-known essays. His new book bridges the gap between two Kosambis—the quantitative scientist and the social historian.

The late historian D.N. Jha had edited a seminal academic volume, The Many Careers of D.D. Kosambi: Critical Essays, bringing together various scholars to trace Kosambi's astounding multidisciplinary prowess, upending fixed orthodoxies in fields ranging from Sanskrit philology to archaeology. Ramaswamy’s biography combines those academic views and further enriches them into a cohesive, intensely personal lifestory. Ramaswamy avoids the trap of writing a biography by grounding chapters in exhaustive primary sources, private letters and institutional records. For example, Jha highlighted how Kosambi utilised the economic history of coins by conducting statistical analyses of currency metal purity and weight. This was to map the decline of long-distance trade and the rise of a self-sufficient village economy, which became the bedrock for the model of ‘Indian Feudalism’. Ramaswamy humanises this highly academic development by leading the reader into the physical spaces where this breakthrough occurred. He traces Kosambi’s interests in numismatics from his time at Harvard to his desk at the Tata Institute of Fundamental Research (TIFR).

Ramaswamy also delves into Kosambi’s pioneering work as a Sanskrit textual critic. Kosambi brought the same mathematical rigour used in numismatics to philology, compiling definitive critical editions of ancient poets such as Vidyakara and Bhartrhari. He has demonstrated how Bhartrhari’s verse resonated with what he called the “groans of the oppressed man”, stripping classical Sanskrit literature of elite Brahminical insulation and pointing to class realities.

Kosambi’s rigour reaches its apex in his radically unconventional treatment of religion. For him, religion was never an isolated playground of theological abstraction. It was a reflection and product of the economic and social realities of its time. As Ramaswamy says, Kosambi viewed religious texts as mirror images of the material production of their era. This unique perspective allowed Kosambi to demystify the rise and fall of Buddhism in India, where he saw Buddhism as a faith fundamentally tied to the demands of early trade, agrarian expansion and urbanisation. In his own writings, Kosambi has noted that “Buddhism becomes understandable only after changes in commerce and urbanisation are grasped.”

Kosambi's lifelong preoccupation with texts like the Bhagavad Gita did not begin in the archives of his later years, but during his lonely days at Harvard University. Drawing on Kosambi’s youthful diaries, Ramaswamy tracks intellectual deliberations between the young Damodar (known to all as ‘Baba’) and his formidable father Dharmanand Kosambi. Dharmanand himself was a towering Pali and Buddhist scholar who had documented his own spiritual and geographic wanderings in his autobiography, Nivedan. Dharmanand viewed the Bhagavad Gita through the lens of early Buddhist moral ethics. But Kosambi's sharp scepticism, which later defined his own historiography, was that the Gita’s religious codes were inextricably bound to social utility rather than to pure ethics.

This is clearer in Kosambi’s iconoclastic reading of the Gita and the figure of Krishna in his 1962 essay, ‘Social and Economic Aspects of the Bhagavad-Gita’. Kosambi dared to look beyond the transcendental poetry of the battlefield to expose the text's social utility. Similarly, he argued that the figure of Krishna was a divine vehicle designed for the “fusion of cults”. For him, the Gita is a literary construct that could appeal to pastoral tribes, rustic peasant producers and elite Brahmins alike.

Ramaswamy’s writing is terse and balanced. He does full justice to Kosambi’s staggering intellectual range without falling into the usual hagiographical trap. He brings out Kosambi’s deep institutional and personal flaws, especially his vanity, thin-skinned reaction to criticisms and his sharp tongue. Kosambi’s brashness defined his public fallout with Homi Bhabha at TIFR and his public attacks on Jawaharlal Nehru. While Bhabha and Nehru built a centralised nuclear state, Kosambi advocated decentralised solar energy to empower the ordinary peasant of rural India. For his defiance and his critique of the Nehruvian economic model as "bourgeois" state capitalism, Kosambi was isolated and ultimately ousted from TIFR in 1962. Yet, what stands out here is Kosambi's commitment to ethics.

During the Cold War, he threw his weight behind the global peace movement by choosing international solidarity over state-sponsored scientific prestige. Today, history is routinely weaponised for immediate political gain and for ideological conformity. Kosambi’s scholarship and his legacy serve as an anchor in our time. One Life, Many Worlds reminds us what it truly means to live a life of the mind—fearless, endlessly inquisitive and profoundly accountable to the world it seeks to explain.
