As the United States marks its 250th year, conversations about faith and national identity are resurfacing — and they offer an occasion to reconsider common assumptions about what “religion” looks like. One striking example: Hindu traditions include vibrant streams that never depended on belief in a personal god, a fact that complicates simple categories of theistic versus secular thought.
The word “Hindu” began as a geographical label, not a creed. Derived from a South Asian name for the Indus river, it was used by outsiders to describe the people and lands beyond that waterway. Over centuries the designation shifted from a regional marker into an umbrella identity for a wide set of cultural, ritual and philosophical practices.
That catch‑all nature matters because it means Hinduism is not a single, uniform theology. Rather, it encompasses a range of approaches to the big questions: the nature of reality, the authority of scripture, and whether the ultimate order of things is personal, impersonal, or simply not supernatural at all.

The scriptural core and competing ways of seeing
At the center of many classical Hindu traditions are the Vedas, texts regarded by many schools as foundational sources of spiritual and cosmological insight. These writings became the starting point for extensive philosophical inquiry rather than a single, settled doctrine.
From those debates arose several influential schools — often called darshanas — that accepted the Vedas as authoritative yet arrived at distinct metaphysical views. They are commonly grouped together because they share that scriptural acceptance, not because they agree on whether the divine is a person or an impersonal principle.
- Sankhya — a dualist system distinguishing matter and consciousness.
- Vaisheshika — categorizes reality into atomic and existential elements.
- Nyaya — a logical and epistemological school focused on methods of knowing.
- Mimamsa — emphasizes ritual action and the authority of Vedic injunctions.
- Yoga — practical and meditative disciplines tied to liberation.
- Vedanta — a broad family of interpretations about the ultimate ground of being.
Despite their differences, these schools are often labeled astika — literally, those who accept the authority of the Vedas. But acceptance of the texts did not necessarily translate into belief in a personal god. Some darshanas read Vedic teachings as pointing to an impersonal cosmic principle or to practices aimed at liberation rather than devotion to a deity.
Non‑theistic streams and the place of Charvaka
Alongside the astika traditions, Indian intellectual history also includes schools that rejected Vedic authority outright. These are usually termed nastika and include well-known traditions such as Buddhism and Jainism, alongside a less familiar but philosophically significant movement: Charvaka.
Charvaka stands out as an explicitly materialist current: it denied supernatural entities, divine revelation, and ritual efficacy, privileging perception and direct experience as sources of knowledge. No complete Charvaka scriptures survive, and much of what we know comes from critiques written by competing traditions, which makes reconstructing its doctrines challenging and open to scholarly debate.
Still, historians and philosophers note that Charvaka represents one of the earliest sustained articulations of materialist and skeptical ideas in South Asia — positions that later debates would engage with and that help explain why South Asian thought cannot be reduced to simple theism.
Why this matters now
Understanding these internal differences within Hindu traditions has practical implications today. For plural democracies — including a 250‑year‑old United States grappling with the place of religion in public life — recognizing that a single religious label can contain theistic, impersonal, and non‑theistic elements encourages a more nuanced public conversation about faith, secularism and rights.
For immigrant communities and religiously diverse publics, it also affects how people are seen and counted in policy debates. Assuming a uniform theology risks erasing minority perspectives within larger religious categories.
- Educational context: Curricula that present religions as monolithic miss important philosophical diversity.
- Public policy: Law and policy that treats religions as uniform may overlook protections for non‑theistic believers.
- Cultural understanding: A finer-grained view prevents stereotyping and enriches interfaith dialogue.
More broadly, the history of non‑theistic thought in South Asia — including materialist critiques that emerged in antiquity — reminds us that skepticism, empiricism and philosophical doubt are not exclusively a Western inheritance. These currents contributed to a global conversation about evidence, authority and the limits of ritual, and they continue to shape how people around the world think about faith and reason.
At a moment when nations reassess what unites them, acknowledging the layered, sometimes contradictory nature of religious traditions can foster a more inclusive civic imagination — one that makes room for belief, doubt, and the many positions in between.
