Jaina Concept of Jiva and Modern Science

Summary

In this philosophical essay Jagdish Prasad Jain expounds the classical Jaina understanding of jīva (soul) and contrasts it with contemporary science and other Indian philosophies. The author begins by defining jīva as a psycho‑physical conscious entity endowed with life‑energies (prāṇa) such as the senses, speech, mind and respiration. These energies are enlivened by an underlying sentient life‑force (bhāva‑prāṇa), making consciousness the distinguishing characteristic of jīva. Jaina doctrine holds that jīva and ajīva (non‑living matter) are two co‑eternal and distinct substances. While matter possesses qualities like touch, taste, smell, sight and hearing, it lacks consciousness; nevertheless, both substances share general attributes such as existence, functionality, changeability, knowability, spatiality and mass. Recognising these dual realities allows Jainism to avoid the extremes of Advaita Vedānta, which reduces the world to a single cosmic consciousness and dismisses the individuality of selves and objects, and materialist monism, which reduces all phenomena to physical states. Jainism’s pluralistic realism posits that consciousness cannot be reduced to neurobiological processes, challenging reductionist positions in modern cognitive science and neurophilosophy. The author argues that Jaina dualism is not akin to Cartesian substance dualism but rather a doctrine of co‑eternal interdependent substances. He critiques John Searle’s notion that consciousness is causally supervenient on brain processes and draws attention to Jaina texts that affirm self‑awareness (svasaṃvedana) as evidence for the existence of an irreducible conscious principle. The essay further analyses contrasting views of self in Buddhist and Advaita traditions. Buddhists deny an enduring self and instead describe the person as a stream of aggregates (skandha), while Advaita attributes individuality to ignorance (māyā). Jainism, by contrast, affirms a permanent individual self that undergoes modes without losing its core identity. The author distinguishes between various states of the self: intentional consciousness (thought‑directed), conditioned self (influenced by karma or environment), ego‑self (imbued with pride and attachment) and the pure self (śuddhātman) which has shed all karmic bondage to attain liberation. He cites classical Jain texts like Kundakunda’s Samayasāra and contemporary research to support these distinctions. Throughout the essay, modern scientific studies are referenced to highlight similarities and differences between Jain concepts and contemporary theories of mind. By emphasising that consciousness cannot be reduced to brain states and by offering a nuanced categorisation of selfhood, the article advocates the relevance of Jaina philosophy in ongoing debates about consciousness, free will and mind‑body interaction.
