3.2 Classical Indian Philosophy

Core Concepts in Classical Indian Philosophy

Classical Indian philosophy tackles some of the biggest questions humans can ask: What is the self? What is reality? How should we live? These ideas, developed over thousands of years starting around 1500 BCE with the Vedic texts, form a rich tradition that approaches these questions differently from Western philosophy. Where Western thinkers often prioritize rational argument and logic, Indian philosophy weaves together metaphysics, ethics, and the pursuit of spiritual liberation.

Core Metaphysical Concepts

Brahman is the ultimate reality and source of all existence. Think of it as the ground of everything: eternal, infinite, and the essence underlying the entire universe. Different schools disagree about Brahman's exact nature, but it sits at the center of Indian metaphysical thought.

Atman refers to the individual self or soul. It's considered eternal and unchanging. In many Hindu traditions, Atman is ultimately identical with Brahman. This is a radical claim: your deepest self is the universal reality. Not every school agrees with this, though, and that disagreement drives some of the most important debates in Indian philosophy.

Maya is the concept that the everyday world we perceive is illusory. It's not that the world doesn't exist at all, but that it veils the true reality of Brahman. Maya explains why we don't naturally recognize the unity of Atman and Brahman.

Karma is the law of cause and effect applied to moral action. Your actions in this life shape your future experiences and future lives. Good actions move you toward moksha (liberation), while harmful actions keep you trapped in the cycle.

Samsara is that cycle: the continuous process of birth, death, and rebirth, driven by karma. Across Hinduism, Buddhism, and Jainism, the ultimate goal is liberation from samsara, though each tradition defines what that liberation looks like differently.

Dualism and Non-Dualism

One of the key debates in Indian philosophy is whether reality is fundamentally one thing or two (or more).

In Samkhya philosophy, reality consists of two irreducible principles:

• Purusha: pure consciousness or the self
• Prakriti: primordial matter, from which the entire material world evolves

These two never merge. Purusha observes; Prakriti acts. Liberation comes when Purusha recognizes itself as distinct from Prakriti. This is a dualist position.

Non-dualist thinkers, especially in the Advaita Vedanta tradition, reject this split. For them, there's only Brahman, and the appearance of separation is the work of maya.

Dharma also plays a central role across Indian thought. It refers to moral, social, and cosmic order, guiding both individual conduct and the harmony of society. Your dharma depends on your role and stage of life, and following it is tied to generating good karma.

Major Schools of Indian Thought

Vedanta

Vedanta is rooted in the Upanishads, the later philosophical portions of the Vedas (the oldest Hindu scriptures). Its central concern is the relationship between Atman and Brahman. Three major sub-schools interpret this differently:

• Advaita (non-dualism): Atman and Brahman are completely identical. All separation is illusion.
• Vishishtadvaita (qualified non-dualism): Atman and Brahman are related but not simply identical. Individual selves are real, but they exist as parts of Brahman.
• Dvaita (dualism): Atman and Brahman are fundamentally distinct. The individual soul and God are separate entities.

Buddhism

Founded by Siddhartha Gautama (the Buddha) in the 5th century BCE, Buddhism breaks from the Hindu tradition in important ways. It rejects the authority of the Vedas and denies the existence of an eternal, unchanging soul (Atman). Instead, Buddhism teaches anatta (no-self): what we call the "self" is really a constantly changing bundle of processes.

The core framework is the Four Noble Truths:

1. Dukkha: Life involves suffering and dissatisfaction.
2. Samudaya: Suffering arises from craving and attachment.
3. Nirodha: Suffering can cease.
4. Magga: The path to ending suffering is the Eightfold Path (right understanding, right intention, right speech, right action, right livelihood, right effort, right mindfulness, right concentration).

The ultimate goal is nirvana, the cessation of suffering and the end of the rebirth cycle.

Jainism

Founded by Mahavira in the 6th century BCE, Jainism shares some concepts with Hinduism and Buddhism but charts its own course. Its core commitments include:

• Ahimsa (non-violence): Jainism takes this further than any other tradition, extending non-harm to all living beings, including insects and microorganisms.
• Asceticism: Spiritual progress comes through disciplined self-denial and detachment from material life.
• Liberation through right knowledge, right faith, and right conduct.

Jainism accepts karma as a real, physical substance that clings to the soul, but it rejects Vedic authority. Liberation means freeing the soul from all karmic matter.

Comparison with Western Philosophical Traditions

Indian and Western philosophy both grapple with fundamental questions about reality, knowledge, and ethics. Both traditions developed multiple competing schools of thought, and both deeply influenced the religious and cultural traditions around them.

The differences, though, are significant:

These are broad generalizations, and exceptions exist on both sides. Some Indian schools (like Nyaya) emphasize logic and formal argument, and some Western thinkers (like the Neoplatonists) pursue mystical unity. But the overall orientations differ: Indian philosophy tends to treat philosophical inquiry as inseparable from the practice of liberation, while Western philosophy more often treats it as an intellectual pursuit in its own right.
