Step 1: Understanding the Concept:
One of the major debates in Indian epistemology is the nature of knowledge's luminosity. Does knowledge only show us the object (like a window), or does it also show itself (like a lamp)? Jainism adopts the Sva-para-prakashaka theory, which means knowledge is self-revealing and object-revealing at the same time. This is a hallmark of Jain realism and its theory of consciousness.
Step 2: Detailed Explanation:
The Jain view of knowledge is captured in the definition:
1. Sva-prakashaka (Self-illuminating): When we know a table, we are also aware of ourselves as the "knower". If knowledge didn't reveal itself, we would need another knowledge to know that we know, leading to an infinite regress (Anavastha). Like a lamp that lights up the room and is also seen by its own light, knowledge makes the soul aware of itself.
2. Para-prakashaka (Object-illuminating): Knowledge must also accurately reflect the external object (the 'Para').
3. Analysis of other school's views:
- Option A (Nyaya View): "Indriya-sannikarsha" suggests knowledge is merely the result of a physical contact between the sense and the object. Jains reject this as being too materialistic and failing to account for non-sensory knowledge (like intuition).
- Option C (Mimamsa/Ancient View): "Karaka-sakalyam" says knowledge is just the sum of the means of production (light, eyes, object). Jains argue knowledge is an inherent quality of the soul, not an accidental product.
- Option D (Charvaka View): Suggests only what we see with eyes is true. Jainism accepts inference and verbal testimony as valid sources too.
The Jain "Sva-para-prakashaka" theory is significant because it maintains the agency of the Soul. It confirms that in every act of knowing the world, the Soul also experiences its own existence. This prevents the "objectification" of the self and ensures that the subject (Jiva) is always present in the process of cognition.
Step 3: Final Answer:
In Jainism, valid knowledge (Pramana) is defined as being "Sva-paraprakashaka", revealing both the knowing subject and the known object simultaneously.
