Cārvāka / Lokāyata materialism
Only perception gives reliable knowledge, so only the material world can be affirmed: no soul survives death, and there is no karma or afterlife.
What can we know without trusting priests or scripture?
In the same ferment of wandering teachers that produced Buddhism and Jainism, some rejected Vedic ritual and the whole idea of rebirth. Their own writings are almost entirely lost; we know them mainly from opponents’ summaries, which makes every reconstruction partial.
An inference needs a universal link (vyāpti) between sign and conclusion, but we can never perceive all cases, so inference cannot prove unseen things such as heaven or a surviving self. What we do perceive is matter: consciousness arises when the elements combine in a body, as intoxicating power arises from fermented ingredients.
- Perception is the only valid means of knowledge.
- Consciousness arises from matter and ends with the body.
- Rituals for the afterlife serve only those who perform them for pay.
No Cārvāka community survived, but its challenge to inference forced Nyāya, Buddhist and Vedāntic thinkers to sharpen their logic, and it is now read as India’s classic voice of materialism and scepticism.

Where it came from
Reacted againstVedic & Upanishadic thoughtCārvākas rejected the Upanishadic self that survives death, and with it the whole scheme of karma and rebirth.
What it led to
Opposed byNyāya–VaiśeṣikaNyāya’s careful theory of invariable concomitance (vyāpti) answered the Cārvāka objection that inference can never be justified.
