Why the Mīmāṃsā school of philosophy argues that all knowledge is inherently true

In short: The Mīmāṃsā school of Hindu philosophy, dating back to the mid-1st millennium BCE, posits a radical epistemological theory: all cognition is intrinsically valid from the start. Rather than seeking proof that a belief is true, Mīmāṃsā scholars argue we should only concern ourselves with proving when a belief is false.

Mīmāṃsā, meaning 'reflection' or 'critical investigation', is one of the six classical Hindu darśanas. Historically known as Pūrva-Mīmāṃsā, it focuses on the earlier Vedic texts—specifically the Brāhmaṇas—which detail ritual actions. Unlike the Vedānta school, which emphasizes the later Upanishads and self-knowledge, Mīmāṃsā centers on dharma as a system of ritual obligations and social duties. Its foundational text, the Mīmāṃsā Sūtra of Jaimini, dates to approximately the 3rd to 2nd century BCE.

The school is famous for its theory of svataḥ prāmāṇyavāda, or the intrinsic validity of knowledge. Mīmāṃsākas argue that because cognition initially appears true, it must be accepted as such unless concrete, verifiable evidence proves it false. This approach shifts the burden of proof: one does not need to justify a belief, but rather must demonstrate why it should be rejected. This logic was used to establish the Vedas as eternal, author-less, and infallible, a framework that later influenced Vedāntic thought.

Epistemologically, the school developed sophisticated means of gaining knowledge, or pramāṇa. While the Prabhākara sub-school recognized five—perception, inference, comparison, postulation, and expert testimony—the Bhāṭṭa sub-school added a sixth: anupalabdhi, or proof by non-perception. This allows for the valid knowledge of negatives, such as the absence of an object in a room. By treating ritual praxis as the noblest necessity of life, Mīmāṃsā scholars sought to guide human action toward unending pleasure, or niratisaya priti, through the precise execution of duty.

Mīmāṃsā remains a distinctively Hindu form of thinking, characterized by its deep analysis of language and its rejection of the need for a systematic examination of Gods. Instead, it views the soul as an eternal, active essence. By demanding that proponents and opponents alike test both positive and negative propositions, the school created a rigorous, law-driven approach to truth that continues to be studied for its unique contributions to exegesis and legal philosophy.
