A Philosophy Before It Was a Programme
Long before “interfaith dialogue” became a recognised academic and diplomatic field, Hindu thought had already articulated its guiding premise in a single Sanskrit phrase: Vasudhaiva Kutumbakam — “the world is one family.” The phrase originates in the Maha Upanishad, where it draws a distinction between the narrow-minded, who divide the world into “mine” and “other,” and the noble-hearted, for whom the entire earth is kin. It is this ancient conviction — not a modern policy slogan, but a spiritual first principle — that inspires the founding ethos of the InterContinental Open University for Global Change.
No single figure carried that principle onto the world stage more effectively than Swami Vivekananda. Over a century before “peacebuilding” and “interfaith harmony” entered the vocabulary of international institutions, he was already living proof that the two were the same undertaking.
From Narendranath Datta to a Global Voice for Hinduism
Swami Vivekananda was born Narendranath Datta in Calcutta (India) in 1863. A disciple of the mystic Sri Ramakrishna Paramahamsa, he inherited from his teacher a conviction that would define his life’s work: that the many religious paths humanity has walked are not competing claims to a single truth, but varied expressions of the same underlying reality. It was this conviction that he carried across the world to Chicago in 1893.
The Parliament of the World’s Religions, 1893
The World’s Parliament of Religions, held in Chicago from September 11 to 27, 1893, was the first sustained attempt to bring representatives of the world’s major faiths onto a single platform. Vivekananda arrived as a relatively unknown monk representing Hinduism to a Western audience for the first time in any formal capacity. His opening address, beginning with the now-famous greeting “Sisters and Brothers of America,” reportedly drew a two-minute standing ovation from an audience of several thousand — a response so immediate that it transformed him almost overnight from an unknown visitor into one of the Parliament’s most sought-after voices.
What made the speech significant was not simply its warmth, but its argument. Vivekananda rejected outright the idea that religious unity could ever be achieved through one faith’s triumph over the others, calling that hope essentially unworkable. In his later addresses during the Parliament, he pressed further, arguing for an end to sectarianism, bigotry, and fanaticism, whether enforced by the sword or by the pen. This was, in effect, a direct address to religious violence and persecution in all their forms — made on a global stage, at a moment when few Western audiences had heard such a case articulated from within a non-Christian tradition.
Scholars and interfaith organisations today widely regard this moment as a foundational event in the modern interfaith movement. The Parliament of the World’s Religions, which continues to operate as an international interfaith body, still displays his opening address on its Chicago office walls, and has publicly described his message as continuing to align with its mission to promote harmony among the world’s religious and spiritual communities.
Harmony, Not Mere Tolerance
Vivekananda was careful to distinguish his message from a simple call for tolerance. Tolerance, in his framing, still implies one party graciously permitting another to exist. What he argued for instead was active acceptance: a recognition that every religious tradition has produced people of genuine holiness and moral depth, and that no single church or creed holds an exclusive claim on virtue. This was not a call to dissolve religious distinctions into a bland sameness, but an invitation to see those distinctions as branches of one shared human search for the sacred — a near-perfect articulation, in modern religious terms, of the Vasudhaiva Kutumbakam ideal.
From Philosophy to Practice
Vivekananda’s contribution to peacebuilding did not end with a single speech. On returning to India, he founded the Ramakrishna Mission in 1897, an organisation that translated his philosophy of universal brotherhood into structured humanitarian service: running hospitals, schools, and disaster relief efforts without regard to the religious identity of those served. In doing so, he modelled a form of practical peacebuilding that peace studies scholars would only later formalise in theory — the idea that lasting harmony is built less through declarations and more through sustained, shared service to human need.
His establishment of Vedanta societies across the United States and Europe further embedded interfaith exchange as an ongoing institutional practice rather than a one-time event, laying groundwork that later scholars in interreligious studies would build on. His influence also extended to other architects of nonviolence and unity who followed him, including Mahatma Gandhi, whose own principles of non-violence and universal welfare echoed the same underlying conviction that humanity’s many communities are, at root, one family.
Why This Matters for Peace Studies Today
For a doctoral researcher working in peace studies or interfaith harmony, Vivekananda’s legacy offers more than historical inspiration. It offers a working model with three components that remain directly relevant to contemporary research questions:
- Public discourse as a peacebuilding tool — his Chicago address demonstrated how a single, well-framed public argument could shift attitudes at a civilisational scale, a question modern researchers still study in the context of media, diplomacy, and public communication.
- Institution-building as the anchor of lasting harmony — the Ramakrishna Mission shows how philosophy translates into durable peacebuilding only when it is embedded in institutions that outlast any one speech or leader.
- Pluralism as method, not just sentiment — his insistence on the equal dignity of all paths offers a conceptual foundation for research into interfaith cooperation that avoids both forced uniformity and mere coexistence.
Vasudhaiva Kutumbakam is often quoted as an ideal. Swami Vivekananda’s life is a reminder that it can also be a method — a way of speaking, organising, and serving that treats the unity of humanity not as a distant hope but as a starting assumption. For an institution founded on that very principle, his example is not simply history to admire. It is a template for the kind of research, and the kind of world, that IOUGC’s scholars are being trained to help build.
