The Cārvāka school, also known as Lokāyata ("philosophy of the people"), is the primary Nāstika (heterodox) school of Indian materialism. It is unique for its rejection of almost all core principles of other Indian philosophies, such as the soul, rebirth, karma, and liberation.
Cārvāka epistemology is the foundation of its entire philosophy. It is radically empiricist.
The Cārvāka school accepts only one valid source of knowledge (Pramāṇa): Perception (Pratyakṣa).
Their argument is as follows:
Flowing directly from their epistemology, Cārvāka's metaphysics is pure materialism. Their motto is: "If I cannot perceive it, it does not exist."
"Consciousness is produced when the elements... combine in a specific proportion. When the body is destroyed, consciousness also perishes."
Since there is no afterlife, no karma, and no soul, the Cārvāka school advocates a form of hedonism.
Jainism is a Nāstika school (it rejects the Vedas) but, unlike Cārvāka, it is deeply spiritual and ethical. It has a robust metaphysics (believing in the soul, karma, and rebirth) and a unique epistemology.
The core of Jaina epistemology and metaphysics is its "pluralism." For Jainism, reality (Tattva) is complex, multifaceted, and possesses infinite aspects. No single human viewpoint can capture the entire truth. This leads to their two most famous doctrines.
Anekānta-vāda literally means "the doctrine of the non-one-sidedness" of reality. It is the metaphysical foundation.
Anekāntavāda is the metaphysical doctrine that all objects and truths are multifaceted and possess infinite, and often contradictory, aspects. Reality is complex, and any single statement about it is at best a partial truth.
For example, an object is permanent in one sense (as substance) but impermanent in another (as its modes or forms change). A person is "tall" (relative to a child) and "not tall" (relative to a building). Both statements are true from different perspectives.
This doctrine is a deliberate rejection of other philosophical schools that make absolute claims (e.g., Buddhism saying "everything is impermanent" or Vedānta saying "only Brahman is permanent"). Jainism holds that they are all partially correct but wrong in their absolutism.
The Parable of the Blind Men and the Elephant: This famous parable, popular in Jainism, perfectly illustrates Anekāntavāda. Several blind men try to describe an elephant:
Each man is correct from his limited perspective, but all are wrong in assuming their partial knowledge is the whole truth. Anekāntavāda is the ability to see that the elephant is all these things and more.

If Anekāntavāda is the metaphysical theory (what reality is), then Syādvāda is its logical and epistemological expression (how we should talk about it).
Since all knowledge is partial and relative to a specific standpoint, Jainism insists that all our judgments (predications) must be qualified. We should not make absolute "is" or "is not" statements. Instead, we must use the qualifier "Syāt" (which means "from a certain point of view," "relatively," or "conditionally").
Syādvāda is the logical doctrine that every statement about reality must be prefixed with "Syāt" (conditionally) to acknowledge its partial and relative nature.
This leads to the Saptabhaṅgī-naya, or the "seven-fold predication," which shows how to express a judgment about an object from different viewpoints:
| Predicate (Naya) | Formulation | Meaning (Example: "Is the pot blue?") |
|---|---|---|
| 1. Syāt-asti | Syāt asti (Conditionally, it is) | From a certain perspective (e.g., its current color), the pot is blue. |
| 2. Syāt-nāsti | Syāt nāsti (Conditionally, it is not) | From another perspective (e.g., its original clay color), the pot is not blue. |
| 3. Syāt-asti-nāsti | Syāt asti ca nāsti ca (Conditionally, it is and is not) | From a combined perspective (e.g., describing it sequentially), the pot is blue (now) and is not blue (originally). |
| 4. Syāt-avaktavyaṃ | Syāt avaktavyam (Conditionally, it is inexpressible) | From a simultaneous perspective, the "is" and "is not" cannot be expressed at the same time. The total reality is inexpressible. |
| 5. Syāt-asti-avaktavyaṃ | Syāt asti ca avaktavyam ca | Conditionally, it is and is inexpressible. (e.g., It is blue, but its total 'is-and-is-not' nature is inexpressible). |
| 6. Syāt-nāsti-avaktavyaṃ | Syāt nāsti ca avaktavyam ca | Conditionally, it is not and is inexpressible. (e.g., It is not blue [in all respects], and this total nature is inexpressible). |
| 7. Syāt-asti-nāsti-avaktavyaṃ | Syāt asti ca nāsti ca avaktavyam ca | Conditionally, it is, is not, and is inexpressible. (This is the most complete, albeit complex, judgment). |
