The Six Pramanas: How We Know What We Know
Top 3 Pramanas Deep. Plus 3 More to Revisit Later.
India's six valid means of knowledge. You master the top 3 in depth: Pratyaksha (perception), Anumana (inference), Shabda (testimony). The remaining 3 (Upamana, Arthapatti, Anupalabdhi) get a one-line tour at the end; you revisit them when you are ready. When someone says "trust the science," which Pramana are they actually invoking, and is the chain valid?
The Question at 9:37 PM
Picture a hypothetical second-year college student, Meera, in her hostel room in Pune on a Tuesday night in March 2021. The second wave of the pandemic is burning through Maharashtra. Her phone shows eighty-three unread WhatsApp messages from her family group. On her laptop, a news panel is live. The anchor is shouting. "Trust the science," he says, stabbing the air with his finger. A doctor on the panel nods. A lawyer argues back. On her phone, her father has forwarded her an image with the caption: "Harvard study proves turmeric cures the virus."
Meera does not know who to believe. The anchor. The doctor. The lawyer. Her father. The question that keeps her awake is older than the pandemic, older than television, older than the state of Maharashtra.
How do you actually know what you know?
Two thousand years before Meera's Tuesday night, a sage named Akshapada Gautama sat down to answer that question the way an engineer answers it. He did not give a speech. He did not write a poem. He wrote a list. His list became the opening of the Nyaya Sutras, the foundational text of Indian logic and debate. It named six doors through which knowledge can enter the mind. You will learn three of them deeply in this lesson. The other three will get a short tour at the end. When you are ready, you come back for them.
Six Doors, Not Two
In the West, a long argument ran from the 1600s to the 1800s. On one side stood the empiricists: John Locke, David Hume. They said all real knowledge comes from the senses. If you cannot see it, touch it, measure it, it is not knowledge. On the other side stood the rationalists: René Descartes, Gottfried Leibniz. They said the senses lie and only reason can reach truth. The two camps fought for almost three centuries.
