I. Introduction to the Theory of Categories in Nyāya-Vaiśeṣika

Historical background and development

• Originated in ancient India around the 6th century BCE
• Nyāya and Vaiśeṣika were initially two separate philosophical systems
  • Nyāya focused on logic and epistemology
  • Vaiśeṣika focused on metaphysics and ontology
• Both systems eventually merged, forming the combined Nyāya-Vaiśeṣika system
  • Shared common ground in their approach to understanding reality
  • Complementary strengths in logic and metaphysics
• Development of the system occurred in three stages:
  • Early period (6th century BCE to 2nd century CE)
    • Foundational texts and concepts established
  • Middle period (2nd century CE to 10th century CE)
    • Expansion and refinement of ideas
    • Interaction with other philosophical systems
  • Late period (10th century CE to 18th century CE)
    • Further development and synthesis of ideas
    • Decline in prominence due to the rise of other philosophical systems

• Each system has its own unique approach to understanding reality, but they share some common themes
  • All systems are rooted in the Vedic tradition
  • They aim to provide a comprehensive understanding of the nature of reality and the path to liberation (Mokṣa)
• Nyāya-Vaiśeṣika has both similarities and differences with other systems
  • Similarities:
    • Shared focus on understanding the nature of reality
    • Use of logic and reasoning to support their claims
  • Differences:
    • Unique emphasis on the theory of categories (Padārthas) as a framework for understanding reality
    • Distinct approach to metaphysics and ontology, including the atomistic theory of creation
• Interaction with other systems led to the development and refinement of ideas
  • Debates and discussions with other systems helped to sharpen the arguments and concepts within Nyāya-Vaiśeṣika
  • Borrowed and adapted ideas from other systems, such as the concept of Pramāṇa (means of knowledge) from Mīmāṃsā

II. Overview of the Nyāya-Vaiśeṣika Categories (Padārthas)

Definition and significance of Padārthas

• Padārthas are fundamental ontological categories in the Nyāya-Vaiśeṣika system.
• Derived from the Sanskrit words “pada” (word) and “artha” (meaning), Padārthas represent the basic building blocks of reality.
• They provide a systematic framework for understanding the nature of existence and the relationships between various entities.
• The Nyāya-Vaiśeṣika system posits that all objects and phenomena can be analyzed and understood through these categories.
• Padārthas serve as a foundation for the epistemological and metaphysical aspects of the Nyāya-Vaiśeṣika philosophy.

Enumeration of the seven categories

1. Dravya (Substance): The material basis of all objects and phenomena, substances are the substratum for qualities and actions. There are nine types of substances: Earth, Water, Fire, Air, Ether, Time, Space, Self (Ātman), and Mind (Manas).
2. Guṇa (Quality): The inherent attributes or properties of substances, qualities are responsible for the various characteristics of objects. There are twenty-four types of qualities, including color, taste, smell, touch, and number.
3. Karma (Action): The activities or processes that bring about change in substances, actions are responsible for the transformation and motion of objects. There are five types of actions: upward movement, downward movement, contraction, expansion, and locomotion.
4. Sāmānya (Universal): The general characteristics or features shared by multiple objects, universals are responsible for the classification and recognition of objects. Examples include the universal “cowness” shared by all cows or the universal “triangularity” shared by all triangles.
5. Viśeṣa (Particular): The unique characteristics or features that distinguish one object from another, particulars are responsible for the individuation and differentiation of objects. Examples include the specific shape, size, or color of a particular object.
6. Samavāya (Inherence): The relationship that connects substances, qualities, and actions, inherence is responsible for the unity and coherence of objects. It is an inseparable and eternal connection between entities.
7. Abhāva (Absence): The non-existence or negation of an object or quality, absence is responsible for the understanding of non-being and negation. There are four types of absence: prior non-existence, posterior non-existence, mutual non-existence, and absolute non-existence.

The role of categories in understanding reality

• The Padārthas provide a comprehensive framework for analyzing and understanding the nature of reality.
• They help to explain the relationships between different entities and their properties, as well as the processes that govern change and transformation.
• By categorizing objects and phenomena into these fundamental categories, the Nyāya-Vaiśeṣika system offers a systematic approach to understanding the world.
• The categories also serve as a basis for the development of logical and epistemological theories within the Nyāya-Vaiśeṣika system.
• The Padārthas provide a foundation for understanding the nature of knowledge, perception, and inference, as well as the criteria for establishing the validity of knowledge claims.
• By understanding the categories and their relationships, one can gain insight into the nature of existence and the underlying principles that govern the world.

III. Substance (Dravya)

Definition and characteristics

• Dravya: A fundamental concept in Nyāya-Vaiśeṣika philosophy, referring to substances or entities that possess qualities and undergo changes.
• Characteristics of Dravya:
  • Independent existence: Substances exist independently and serve as the substratum for qualities and actions.
  • Possessing qualities (Guṇa) and actions (Karma): Substances are the bearers of various qualities and actions.
  • Capable of undergoing change: Substances can undergo transformations and modifications.
  • Eternal or non-eternal: Some substances are eternal, while others are non-eternal, depending on their nature.

Nine types of substances

1. Earth (Pṛthivī):
   • Solid, tangible, and characterized by smell.
   • Composed of atoms (Paramāṇu) that combine to form larger aggregates (Anu).
   • Examples: rocks, soil, metals, and minerals.
2. Water (Ap):
   • Liquid, characterized by taste.
   • Composed of water atoms that combine to form larger aggregates.
   • Examples: rivers, lakes, and oceans.
3. Fire (Tejas):
   • Characterized by heat, light, and color.
   • Composed of fire atoms that combine to form larger aggregates.
   • Examples: flames, sunlight, and heat.
4. Air (Vāyu):
   • Gaseous, characterized by touch.
   • Composed of air atoms that combine to form larger aggregates.
   • Examples: wind, breeze, and atmospheric gases.
5. Ether (Ākāśa):
   • Subtle, all-pervading, and characterized by sound.
   • Eternal and indivisible, not composed of atoms.
   • Provides space for other substances to exist and interact.
6. Time (Kāla):
   • Subtle, eternal, and responsible for the sequence of events.
   • Indivisible and all-pervading.
   • Enables the perception of change, duration, and succession.
7. Space (Dik):
   • Subtle, eternal, and responsible for the spatial arrangement of objects.
   • Indivisible and all-pervading.
   • Provides the framework for the location and direction of substances.
8. Soul (Ātman):
   • Subtle, eternal, and conscious.
   • The substratum for cognition, volition, and experience.
   • Exists in all living beings, from plants to humans.
9. Mind (Manas):
   • Subtle, non-eternal, and responsible for mental activities.
   • Acts as an intermediary between the soul and the senses.
   • Instrument for perception, cognition, and volition.

The relationship between substances and qualities

• Substratum for qualities: Substances serve as the foundation for qualities to inhere. Qualities cannot exist independently of substances.
• Inherence (Samavāya): The relationship between substances and their qualities is one of inherence, a unique type of connection in Nyāya-Vaiśeṣika philosophy.
• Changes in substances: The presence or absence of certain qualities can lead to changes in substances, such as transformations, combinations, or divisions.
• Perception of substances: The perception of substances is often mediated through their qualities, as the senses detect the qualities associated with a particular substance.
• Causation: Substances play a crucial role in the causal processes, as they serve as the material cause for the production of new substances or the modification of existing ones.

IV. Quality (Guṇa)

Definition and characteristics

• Guṇa: A fundamental concept in the Nyāya-Vaiśeṣika system, referring to the inherent qualities or attributes of substances (dravyas).
• Inseparability: Guṇas are inseparable from the substances they inhere in, and cannot exist independently.
• Multiplicity: A single substance can possess multiple qualities simultaneously.
• Variability: Qualities can vary in degree or intensity within a substance.
• Cognition: Guṇas are the basis for our perception and cognition of the external world.

Twenty-four types of qualities

1. Color (Rūpa): The visual appearance of an object, such as red, blue, or yellow.
2. Taste (Rasa): The flavor of a substance, such as sweet, sour, or bitter.
3. Smell (Gandha): The odor of a substance, such as fragrant, pungent, or foul.
4. Touch (Sparśa): The tactile sensation of an object, such as hot, cold, smooth, or rough.
5. Number (Saṅkhyā): The numerical quantity of a group of objects, such as one, two, or three.
6. Size (Parimāṇa): The dimensions or magnitude of an object, such as small, medium, or large.
7. Separateness (Prthaktva): The distinctness or individuality of an object, distinguishing it from others.
8. Conjunction (Saṃyoga): The physical contact or union between two or more substances.
9. Disjunction (Vibhāga): The separation or division between two or more substances.
10. Priority (Paratva): The relative position or order of objects in space or time.
11. Posteriority (Aparatva): The opposite of priority, referring to the later position or order of objects in space or time.
12. Intelligence (Buddhi): The cognitive faculty or capacity for knowledge and understanding.
13. Pleasure (Sukha): The positive or enjoyable mental state or experience.
14. Pain (Duḥkha): The negative or unpleasant mental state or experience.
15. Desire (Icchā): The mental inclination or longing for an object or experience.

23. Resilience (Vīrya): The capacity for endurance, strength, or vitality.
24. Life (Jīvitā): The vital force or principle that sustains living beings.

The relationship between qualities and substances

• Inherence: Qualities (guṇas) inhere in substances (dravyas) through a unique relationship called samavāya, which connects them inseparably.
• Perception: The presence of qualities in substances allows us to perceive and cognize the external world through our sensory faculties (indriyas).
• Causation: Qualities play a crucial role in the causal processes that govern the interactions and transformations of substances in the world.
• Knowledge: Understanding the qualities of substances is essential for acquiring knowledge about the nature of reality and the workings of the universe.
• Ethics: Certain qualities, such as merit (dharma) and demerit (adharma), are central to the ethical dimensions of human life and the pursuit of liberation (mokṣa) in the Nyāya-Vaiśeṣika system.

V. Action (Karma)

Definition and characteristics

• Action (Karma): A fundamental category in Nyāya-Vaiśeṣika philosophy that refers to the inherent capacity of substances to undergo change or produce effects.
• Inseparable from substances: Actions are always associated with substances and cannot exist independently.
• Cause of change: Actions are responsible for the transformation, motion, and interaction of substances in the world.
• Non-eternal: Unlike substances and qualities, actions are considered non-eternal, as they have a beginning and an end.
• Non-repetitive: An action, once performed, cannot be repeated in the same form, as it is unique to the specific time and context in which it occurs.

Five types of actions

1. Utkṣepaṇa (upward motion): The action of moving or being propelled upwards, such as the upward movement of a ball thrown into the air.
2. Avaṣepaṇa (downward motion): The action of moving or being pulled downwards, such as the downward movement of a ball falling due to gravity.
3. Ākūnchana (contraction): The action of becoming smaller or more compact, such as the contraction of a muscle or the shrinking of a material when cooled.
4. Prasāraṇa (expansion): The action of becoming larger or more spread out, such as the expansion of a muscle or the swelling of a material when heated.
5. Gamana (locomotion): The action of moving from one place to another, such as the movement of a person walking or the motion of a vehicle.

The role of action in causation and change

• Causation: Actions play a crucial role in the process of causation, as they are responsible for the interaction between substances and the production of effects.
  • Example: The action of striking a match (Karma) causes the substance of the matchstick (Dravya) to undergo a change, resulting in the production of fire (effect).
• Change: Actions are the driving force behind the transformation and motion of substances in the world.
  • Example: The action of heating a metal rod (Karma) causes the substance of the metal (Dravya) to expand (change).
• Law of Karma: In Indian philosophy, the concept of Karma is often associated with the moral and ethical consequences of one’s actions. The Nyāya-Vaiśeṣika understanding of action, while not directly concerned with morality, provides a framework for understanding the causal relationships between actions and their effects.
  • Example: The action of performing a good deed (Karma) may result in positive consequences for the individual (effect), while the action of committing a harmful act (Karma) may lead to negative consequences (effect).

VI. Universals (Sāmānya)

Definition and characteristics

• Sāmānya: A fundamental concept in Nyāya-Vaiśeṣika philosophy, referring to universals or general characteristics shared by multiple objects.
• Characteristics of Sāmānya:
  • Shared by multiple objects: Universals are common features that are present in more than one object.
  • Responsible for classification: Universals help in classifying objects based on their shared characteristics.
  • Abstract and eternal: Universals are considered abstract entities that exist eternally, independent of particular instances.

Hierarchical structure of universals

• Hierarchy of Sāmānya: Universals can be organized into a hierarchical structure based on the level of generality.
  • Higher-order universals: More general universals that subsume lower-order universals. For example, “living being” is a higher-order universal that includes “animal” and “plant” as lower-order universals.
  • Lower-order universals: More specific universals that are subsumed by higher-order universals. For example, “cow” and “horse” are lower-order universals subsumed by the higher-order universal “animal.”
• Relations between universals: Universals can be related to each other through various relations, such as subsumption, exclusion, and intersection.
  • Subsumption: A relation in which one universal includes another universal. For example, “animal” subsumes “cow” and “horse.”
  • Exclusion: A relation in which two universals do not share any instances. For example, “cow” and “horse” are exclusive universals, as no object can be both a cow and a horse.
  • Intersection: A relation in which two universals share some instances. For example, “red” and “round” intersect in the set of red, round objects.

The role of universals in cognition and language

• Cognition: Universals play a crucial role in human cognition, as they enable the mind to recognize, classify, and understand objects based on their shared characteristics.
  • Concept formation: Universals help in forming mental concepts by abstracting common features from particular instances.
  • Inductive reasoning: Universals facilitate inductive reasoning, as they allow the mind to generalize from specific instances to broader categories.
• Language: Universals also play a significant role in language, as they provide the basis for the formation of linguistic categories and the structure of meaning.
  • Linguistic categories: Universals help in forming linguistic categories, such as nouns, adjectives, and verbs, which represent shared features of objects, qualities, and actions.
  • Structure of meaning: Universals contribute to the structure of meaning in language, as they enable words to refer to shared characteristics of objects, rather than particular instances.
  • Communication: Universals facilitate communication, as they allow speakers to convey information about objects and their properties based on shared understanding of common features.

VII. Particulars (Viśeṣa)

Definition and characteristics

• Viśeṣa: A fundamental concept in Nyāya-Vaiśeṣika philosophy, referring to the unique features or characteristics that distinguish one object from another.
• Characteristics of Viśeṣa:
  • Individuating: Particulars serve to differentiate one object from another, even if they share the same universal characteristics.
  • Inseparable: Particulars are inseparable from the substances they individuate and cannot exist independently.
  • Eternal: Particulars are considered eternal, as they do not undergo change or destruction.

The role of particulars in individuation and distinction

• Individuation: Particulars play a crucial role in the process of individuation, which is the differentiation of one object from another based on their unique features.
  • Example: Two cows may share the same universal “cowness,” but their unique features, such as size, color, or markings, individuate them as distinct entities.
• Distinction: Particulars help to establish the distinction between objects, even when they share common universal characteristics.
  • Example: Two red apples may share the universal “redness” and “appleness,” but their unique features, such as size or shape, distinguish them as separate entities.

The relationship between particulars and universals

• Complementary roles: Particulars and universals play complementary roles in the Nyāya-Vaiśeṣika system, with universals accounting for the common features shared by multiple objects, and particulars accounting for the unique features that differentiate them.
• Inherence: The relationship between particulars and universals is one of inherence (Samavāya), with particulars inhering in the substances they individuate.
• Cognition: Both particulars and universals play important roles in the process of cognition, as the mind perceives objects by recognizing both their universal and particular features.
  • Example: When perceiving a cow, the mind recognizes both the universal “cowness” and the unique features (particulars) that individuate the specific cow being perceived.
• Language: Particulars and universals also play a role in language, as words and concepts often involve both the recognition of universal features and the differentiation of particular instances.
  • Example: The word “cow” refers to the universal “cowness,” while specific instances of cows are distinguished by their unique features (particulars).

VIII. Inherence (Samavāya)

Definition and characteristics

• Inherence (Samavāya): A fundamental concept in Nyāya-Vaiśeṣika philosophy, referring to the unique and inseparable relationship between entities, such as substances and their qualities or actions.
• Characteristics of Samavāya:
  • Inseparability: Inherence is an eternal and inseparable connection between entities, meaning that the entities cannot exist independently of each other.
  • Non-transitivity: The relationship of inherence is non-transitive, meaning that if A inheres in B and B inheres in C, it does not necessarily follow that A inheres in C.
  • Asymmetry: Inherence is an asymmetric relationship, meaning that if A inheres in B, it does not follow that B inheres in A.

Types of inherence relationships

1. Substance-Quality (Dravya-Guṇa) inherence: The relationship between a substance and its inherent qualities. For example, the color red inheres in a red apple, and the taste sweet inheres in sugar.
2. Substance-Action (Dravya-Karma) inherence: The relationship between a substance and its inherent actions or processes. For example, the action of burning inheres in fire, and the action of flowing inheres in water.
3. Universal-Particular (Sāmānya-Viśeṣa) inherence: The relationship between a universal and the particular instances that instantiate it. For example, the universal “cowness” inheres in each individual cow, and the universal “triangularity” inheres in each individual triangle.

The role of inherence in connecting categories

• Connecting substances, qualities, and actions: Inherence plays a crucial role in the Nyāya-Vaiśeṣika system by connecting substances with their qualities and actions. This connection allows for a coherent understanding of the nature of objects and the changes they undergo.
• Explaining the unity of objects: Inherence helps to explain the unity and coherence of objects by providing a framework for understanding how various entities are related to one another. For example, the inherence of color, taste, and other qualities in a substance helps to explain the unity of that substance as a single, coherent object.
• Basis for causal relationships: Inherence also plays a role in understanding causal relationships between entities. For example, the inherence of an action in a substance can help to explain how that substance causes changes in other substances.
• Facilitating knowledge and cognition: The concept of inherence is essential for understanding how knowledge and cognition are possible. By connecting substances with their qualities and actions, inherence provides a basis for the perception and recognition of objects, as well as the formation of concepts and categories.

IX. Absence (Abhāva)

Definition and characteristics

• Abhāva: A fundamental category in Nyāya-Vaiśeṣika philosophy, referring to the absence or non-existence of an object or quality.
• Characteristics of Abhāva:
  • Negative entity: Abhāva represents the negation or non-being of something, as opposed to the positive existence of substances, qualities, and actions.
  • Dependent on a substratum: Abhāva is always related to a specific substratum, which can be a substance, quality, or action.
  • Involves a counter-positive: Abhāva is defined in relation to a positive entity, known as the counter-positive (prasajya-pratiyogin), which is the object or quality that is absent.

Four types of absence

1. Prior non-existence (Prāgabhāva):
   • Refers to the absence of an object or quality before it comes into existence.
   • Example: The absence of a pot before it is created from clay.
2. Posterior non-existence (Pradhvaṃsābhāva):
   • Refers to the absence of an object or quality after it ceases to exist.
   • Example: The absence of a pot after it is broken into pieces.
3. Mutual non-existence (Anyonyābhāva):
   • Refers to the absence of one object or quality in another, indicating their distinctness and non-identity.
   • Example: The absence of a pot in a cloth, as they are two distinct objects.
4. Absolute non-existence (Atyantābhāva):
   • Refers to the absence of an object or quality that is impossible or contradictory, and therefore can never exist.
   • Example: The absence of a square circle, as it is a logically contradictory concept.

The role of absence in negation and non-existence

• Understanding negation: Abhāva helps to explain the concept of negation in the Nyāya-Vaiśeṣika system, as it provides a way to account for the non-existence of objects and qualities.
• Cognition of absence: The recognition of absence is an important aspect of human cognition, as it allows us to understand the difference between presence and absence, and to reason about what is not present in a given situation.
• Ontological status: Abhāva is considered a real and independent category in the Nyāya-Vaiśeṣika system, as it is distinct from the positive entities of substances, qualities, and actions.
• Inference and reasoning: The concept of absence plays a crucial role in logical inference and reasoning, as it enables us to draw conclusions based on the absence of certain conditions or evidence.
• Language and communication: Abhāva is also important in language and communication, as it allows us to express negation, denial, and contradiction, which are essential for conveying complex ideas and engaging in debates and discussions.

X. Criticisms and Defense of the Nyāya-Vaiśeṣika Theory of Categories

Criticisms from other Indian philosophical systems

• Sāṃkhya: The Sāṃkhya system criticizes the Nyāya-Vaiśeṣika theory of categories for its atomistic approach to reality, arguing that the ultimate constituents of reality are the principles of Puruṣa (consciousness) and Prakṛti (matter), rather than the substances, qualities, and actions posited by Nyāya-Vaiśeṣika.
• Buddhism: The Buddhist school of thought, particularly the Madhyamaka and Yogācāra schools, criticize the Nyāya-Vaiśeṣika system for its adherence to the concept of eternal, unchanging substances, arguing instead for the doctrine of dependent origination (pratītyasamutpāda) and the ultimate emptiness (śūnyatā) of all phenomena.
• Advaita Vedānta: The Advaita Vedānta school criticizes the Nyāya-Vaiśeṣika theory of categories for its focus on the multiplicity of substances and qualities, arguing that the ultimate reality is the non-dual Brahman, which transcends all categories and distinctions.

Responses from Nyāya-Vaiśeṣika philosophers

• Defense of atomism: In response to the Sāṃkhya criticism, Nyāya-Vaiśeṣika philosophers argue that their atomistic approach provides a more coherent and parsimonious explanation of the nature of reality, as it accounts for the diversity and complexity of the world without positing an infinite regress of principles.
• Defense of eternal substances: In response to the Buddhist criticism, Nyāya-Vaiśeṣika philosophers argue that the concept of eternal, unchanging substances is necessary to account for the continuity and stability of the world, and that the doctrine of dependent origination does not provide a satisfactory explanation for the existence of objects and their properties.
• Defense of multiplicity: In response to the Advaita Vedānta criticism, Nyāya-Vaiśeṣika philosophers argue that the multiplicity of substances and qualities is a fundamental aspect of reality, and that the non-dual Brahman cannot account for the diversity and complexity of the world.

Modern evaluations of the theory of categories

• Metaphysical insights: Modern philosophers and scholars have recognized the value of the Nyāya-Vaiśeṣika theory of categories in providing a systematic and coherent framework for understanding the nature of reality, as well as its contributions to the development of Indian metaphysics and ontology.
• Epistemological contributions: The Nyāya-Vaiśeṣika system’s focus on logic, reasoning, and the criteria for establishing the validity of knowledge claims has been recognized as an important contribution to the development of Indian epistemology and the philosophy of knowledge.
• Comparative studies: The theory of categories has been the subject of comparative studies with other philosophical systems, both within the Indian tradition and in Western philosophy, highlighting the similarities and differences between the Nyāya-Vaiśeṣika approach and other theories of reality.
• Relevance to contemporary debates: The Nyāya-Vaiśeṣika theory of categories has been found to be relevant to contemporary philosophical debates in areas such as metaphysics, ontology, and the philosophy of language, as well as to interdisciplinary discussions in fields such as physics, biology, and cognitive science.
