Pratyakṣa
from 200 BCE Nyāya Sūtra; refined for centuries by Buddhist logicians
What is actually given in perception, as distinct from what was immediately added to it — and the difference matters more than it seems.

What it is
Pratyakṣa is knowledge arising from the contact of a sense with its object, without the mediation of inference or words. Every school admits it; no school agrees about what it delivers.
The central Indian dispute is whether perception is nirvikalpaka — bare, wordless, before any classification — or savikalpaka, already carrying the concept. Dignāga holds that only the bare version is really perception and everything else is inference wearing perception's clothes. That distinction is the useful part.
How it works
Take the perceptual report. Separate what the senses were in contact with from what was supplied by recognition, expectation or naming. Ask which parts of the report would survive if the observer had no name for what they saw. What remains is the perceptual content; the rest arrived by another route and should be checked by that route's conditions.
The form of the inference
- A sense faculty was in contact with an object
- A cognition arose immediately from that contact
- The cognition is not derived from words or from inference
- Therefore its bare content is known by perception, and whatever was added to it is not
The argument
Proposition The inspector's report contains one observation and three conclusions.
- The report reads: I observed active termite damage to the bearer, ongoing for two to three years, originating from the stump to the south-east.
- Separate what the senses were in contact with: galleries in the timber of the bearer, frass, and a mud lead on the pier.
- Active is not perceived. It is inferred from the moisture of the frass and the intact mud lead, and that inference has its own conditions, including that the lead was not merely recent rain.
- Two to three years is not perceived. It is inferred from the extent of the galleries against an assumed rate, and the rate is testimony from a manual rather than anything seen.
- Originating from the stump is not perceived either. No connection between the stump and the pier was excavated; the origin was inferred from proximity.
Therefore One thing was perceived and three were inferred, and the three inferences have conditions the report does not address — so the finding of active damage is not supported in the way the word observed implies.
Nothing in the report is necessarily wrong. What the separation shows is that a single word, observed, was carrying one perception and three inferences, and only one of them had been checked.
What it is good for
Reading any report by an expert observer — inspection, clinical examination, forensic work, witness testimony. Separating the seen from the concluded is the fastest way to find where the weight is really resting.
Where it fails
The separation may not be available. If perception is always already conceptual, as the Naiyāyikas argued against Dignāga, then there is no bare given to isolate and the method is separating something from nothing.
And bare perception, if it exists, is close to useless on its own. Dignāga's own position drives him to say that what perception delivers is a wordless particular that cannot be reported — which makes it unimpeachable and unusable at the same time, and the tension was never resolved.
Common misconceptions
That it corresponds to Western sense-data theory. The Indian debate is about whether conceptual content is present in the cognition, not about whether we perceive mental intermediaries — and most Indian schools are direct realists, which sense-data theory is not.
Where it came from
The Nyāya Sūtra defines it; Dignāga in the fifth century and Dharmakīrti in the seventh build the most sophisticated treatment, arguing that perception is bare and conceptless.
What became of it
A live debate for over a thousand years between Buddhist and Nyāya logicians, and one of the most technically refined discussions of perception in any tradition.
Lasting influence
The Buddhist position anticipates the modern debate about non-conceptual content by more than a millennium.
Why it still matters
Directly useful whenever an expert report has to be read carefully.

Texts
Dignāga, Pramāṇasamuccaya
The first chapter is on perception and is the origin of the bare-perception position.
Where to start
Matilal's Perception again — it sets the Indian debate against the Western one without flattening either.
The surprising bit
Two traditions argued for a thousand years about whether perception comes with concepts already in it, and analytic philosophy arrived at the same dispute in the 1990s apparently without knowing.
In their own words
Perception is free from conceptual construction

The verdict
A sharp and immediately usable distinction resting on a question about the mind that has never been settled anywhere.
