Key Themes and Content:

Historical Overview (Pṛṣṭhabhūmi / Background):
- Introduction to Nyaya Shastra: The text begins by defining Nyaya Shastra as the science of logic, reasoning, and knowledge acquisition, also known as Tarka Shastra, Hetuvidya, or Pramana Shastra. Its ancient name, Ānvīkṣikī, is discussed as a fundamental discipline for understanding truth and rectifying fallacies. Kautilya's Arthashastra and Vatsyayana's Nyaya Bhashya are cited to illustrate the importance of Ānvīkṣikī for intellectual development and its application in various fields, including spiritual knowledge.
- Jain Perspective on Nyaya: The book emphasizes that Jain philosophy is rooted in Anekāntavāda (non-absolutism or multi-faceted reality), which is the cornerstone of Jain thought and practice. This perspective, which avoids rigid, one-sided views, is seen as the distinguishing feature of Jain logic. The text explains that Syādvāda is the linguistic expression of Anekāntavāda, signifying that every statement is true from a particular viewpoint.
- Historical Development of Jain Logic: A significant portion of the introduction surveys the evolution of Jain logic, highlighting the contributions of various Jaina scholars from ancient times up to the medieval period. It traces the development from early thinkers to the foundational contributions of Acarya Kundakunda and Acarya Umasvati, who laid the groundwork for Jain epistemology. The seminal work of Acarya Samantabhadra is recognized for establishing the framework of Syādvāda and Anekāntavāda in logical discourse. The crucial role of Acarya Siddhasena is acknowledged for further developing Jain logic, particularly through works like Nyayavatara. The contributions of later logicians like Sridatta, Patrakesari, Mallavadi, Sumati, Akalanka Deva, Vidyānanda, Prabhachandra, Vadirāja, Abhayadeva, Vādisūri, and Hemachandra are discussed in detail, showing how they refined and defended Jain logical principles against other philosophical schools. The pivotal role of Bhatta Akalanka is emphasized as a major proponent who systematized Jain logic in Sanskrit, responding to critiques from Buddhist and Hindu logicians.
Pramāṇa (Means of Knowledge):
- Jain Conception of Pramāṇa: The core of Jain logic lies in its theory of Pramāṇa. The text defines Pramāṇa as that which leads to valid and certain knowledge, a knowledge that is unfailing (avisamvadi) and clarifies the unknown (anadhigata). The author explains the Jain emphasis on the subjective, cognitive aspect of knowledge itself as the Pramāṇa, rather than the external factors like sense contact.
- Types of Pramāṇa: Jainism primarily recognizes two main types of Pramāṇa:
  - Pratyaksha (Direct Perception): This is knowledge that arises directly from the soul, without the intervention of external sense organs. It is further categorized into:
    - Sakalapratyaksha (Omniscience/Perfect Direct Perception): This is Kevalajnana (Absolute Knowledge), possessed by Tirthankaras and Siddhas, which perceives all realities simultaneously.
    - Vikalapratyaksha (Imperfect Direct Perception): This is the direct perception available to embodied souls, which is limited by the soul's inherent limitations and the presence of obscuring karma. It is divided into:
      - Avadhi Jnana: Direct knowledge of form and subtle matters within a limited spatial and temporal scope.
      - Manahparyaya Jnana: Direct knowledge of the thoughts of others' minds.
  - Paroksha (Indirect Perception): This is knowledge obtained through the senses and mind, which is indirect and inferential in nature. It is further divided into:
    - Mati Jnana: Sensory and mental knowledge, which is the primary indirect knowledge. It involves stages like avagraha (initial perception), iha (enquiry), avāya (determination), and dhāraṇā (retention).
    - Shruta Jnana: Knowledge derived from scriptures or testimony, which follows Mati Jnana.
- Critique of Other Schools' Pramāṇas: The book systematically analyzes and critiques the Pramāṇa theories of other Indian philosophical schools, such as the sannikarsha (sense contact) theory of the Naiyayikas, the indriyavṛtti (sense activity) theory of the Samkhyas, the jñātṛvyāpāra (knower's activity) theory of the Mimamsakas, and the nirvikalpaka (indeterminate perception) theory of the Buddhists. Shastri argues against these theories, demonstrating how they fail to fully account for valid knowledge and often contradict Jain principles.
- Pramāṇābhāsa (Fallacious Knowledge): The text also discusses the concept of Pramāṇābhāsa, which are erroneous cognitions that appear to be valid but are ultimately deceptive, such as viparyaya (misperception), saṃśaya (doubt), and anadhikarana (unconnected cognition).
Syādvāda, Nayavāda, and Saptabhaṅgī:
- Syādvāda: The book thoroughly explains Syādvāda as the doctrine of conditional predication, emphasizing that reality is viewed from multiple perspectives, and any assertion is true only from a particular viewpoint (syāt). This doctrine is presented as the logical methodology that upholds Anekāntavāda.
- Nayavāda: Nayavāda, the theory of standpoints or perspectives, is presented as a crucial tool derived from Syādvāda. It explains how different viewpoints (nayavāda) highlight specific aspects of reality. The text details the classification of nayavāda into dravyārthika (focusing on substance) and paryāyārthika (focusing on modes/qualities), and their respective sub-categories.
- Saptabhaṅgī: The sevenfold approach (saptabhaṅgī), a logical structure based on Syādvāda, is expounded. This method systematically explores various combinations of affirmation, negation, and indeterminacy to describe reality's multi-faceted nature. The book explains the seven propositions: syādasti (from a certain perspective, it is), syānnāsti (from a certain perspective, it is not), syādastināsti (from a certain perspective, it is and it is not), syādavaktavya (from a certain perspective, it is indeterminate), syādasti avaktavya (from a certain perspective, it is and is indeterminate), syānnāsti avaktavya (from a certain perspective, it is not and is indeterminate), and syādasti nāsti avaktavya (from a certain perspective, it is, it is not, and is indeterminate).
Critique of Other Philosophical Systems: Shastri critically examines and refutes the logical and epistemological positions of other prominent Indian philosophical schools, including:
- Buddhism: Critiques of Buddhist theories like nirvikalpaka pratyaksha (indeterminate perception), apohavāda (theory of exclusion), and kṣaṇabhaṅgavāda (momentariness).
- Nyaya-Vaisheshika: Critiques of sannikarsha (sense contact), kāraka sākalya (aggregate of causes), iśvaravāda (theism), and their theories of perception and inference.
- Mimamsa: Critiques of svataḥ prāmāṇya (inherent validity) and parataḥ aprāmāṇya (derived invalidity), and their views on arthāpatti (postulation) and the nature of words.
- Samkhya: Critiques of their indriyavṛtti (sense activity) theory and the nature of knowledge as unconscious.
Jain Epistemology: The book clarifies the Jain understanding of knowledge, emphasizing its inherent luminosity (svaprakāśaka) and its role in both self-awareness and the apprehension of external objects.
