Early Buddhism — Anātman, Dependent Origination, and the Middle Path
The Buddha's original philosophical revolution: accepting the Vedic framework of karma, saṃsāra, and liberation entirely — then denying the self (ātman) that Vedic thought placed at the centre of that framework. The doctrine of anātman and dependent origination (pratītyasamutpāda) are the two hinges on which the entire edifice of Buddhist philosophy turns.
The central move: anātman
The Buddha did not reject the Indian metaphysical framework — he radicalised it. Karma, rebirth, saṃsāra, liberation: all accepted. But the presupposition of that framework — that there is a permanent, unchanging self (ātman) doing the karmic actions and accumulating the rebirths — this he denied.
Instead: the five aggregates (pañca-skandha) — form, feeling, perception, mental formations, consciousness — constitute what we call a 'person'. None is the self. Together they do not constitute a self either. What we call 'I' is a conventional designation for a causally connected process, not a substance.
Pratītyasamutpāda — dependent origination
All phenomena arise in dependence on conditions (pratītyasamutpāda). Nothing has independent, intrinsic existence. The twelve-linked chain of dependent origination traces the arising of suffering from ignorance through craving, attachment, and becoming to birth, aging, and death.
The liberating insight: since suffering arises from conditions, it can cease when those conditions cease. Liberation is not an achievement but a cessation — the extinguishing (nirvāṇa, literally 'blowing out') of the conditions that sustain the suffering process.
