Cognition of the self

How does one know about the self, according to the three main schools discussed in my last post?

Buddhist Epistemological School (Dharmakīrti): the self does not exist. The only thing that exists is a stream (santāna) of causally linked momentary cognitions. Cognitions are self-aware of themselves qua cognitions (svasaṃvedana). This is not contradictory, because each cognition has a perceiver and a perceived aspect (grāhaka and grāhya-ākāra respectively).
Nyāya: the self is known only through inference (Vātsyāyana, Jayanta); it is known also through perception (Uddyotakara, Udayana)*
Bhāṭṭa Mīmāṃsā (Kumārila): we have direct access to our self through ahampratyaya `cognition of the I’. No need to infer it, since perception trumps inference and Mīmāṃsā authors require novelty as a criterion for knowledge, so that repeating what is already known through ahampratyaya would not count as knowledge.

The first Nyāya position might lead to problems if connected with the acceptance of yogic perception. Yogins can indeed perceive the self, according to all Naiyāyikas. Why not all other beings, given that perception requires a conjunction of self+manas+sense faculties, that the self is pervasive (vibhu) and that spatial limits are not needed for perception, as shown by the case of absence? Jayanta explains that the self is partless and that a partless thing cannot simultaneously be perceiver and perceived (cf. Kumārila’s argument against the Buddhist idea of cognitions’ having a perceiver and a perceived aspect and Kumārila’s claiming that this does not apply to the self, which is complex and not partless).

The Mīmāṃsā position requires the joint work of intrinsic validity and falsification: some I-cognitions are not about the ātman, since they are indeed falsified (e.g., “I am thin”, which only refers to the body).
Other I-cognitions are not, e.g., cognising ourselves qua knowers and recognising ourselves as the same knower who knew something in the past.

Intro to Sanskrit philosophy

Background: This year I taught again a class on Sanskrit philosophy (for the first time since 2021). I only had 12 meetings, of three hours each, hence I had do made drastic choices. The following is the result of these choices (alternative choices could have been possible, e.g., focusing on the Upaniṣads and their commentaries). Comments, as usual welcome!

There is a time within Sanskrit philosophy, approximately around 500 to 1000 CE, without which all later discussions do not make sense (whereas one can understand later discussions without referring to, e.g., the Brāhmaṇas, the Pāli canon etc.).
I am thinking of this core of Sanskrit philosophy as the period of time in which philosophers interacted with each other in a dialectical way, learning from each other and being compelled by each other’s points. In other words, as the time in which philosophy was constrained by the need to give reasons for each claim. In this sense, I am not focusing on the Pāli Canon or on the Upaniṣads.

At the core of this period lies the interaction between three schools, namely Mīmāṃsā, Nyāya and Buddhist epistemological school. No matter the topic, the interaction among these three is always at the center and always needs to be taken into account. According to the various topics, further schools might need to be taken into account. For instance, discussions about atomism will need to take into account the Vaiśeṣika school, discussions about language need to take into account the Vyākaraṇa school.

At the center of this core moment are discussions about epistemology and philosophy of language. It is interesting to note that ontology does not necessarily logically precede epistemology and that the opposite can be the case, especially in the case of Mīmāṃsā. This is particularly evident in the case of discussions about prāmāṇya `validity’.

Sanskrit philosophy developed through debates among thinkers commenting and responding to each other. In this way, they showed that ‘novelty’ is overestimated as a criterion to assess philosophical value and its consistent presence among the criteria reviewers of grants and projects are asked to assess is more the result of a fashion than of inner-philosophical reasons.

This does not mean that individual authors did not deliver substantial contribution to philosophy. Philosophy develops through its history and its history is made by individual thinkers. Nonetheless, these individual thinkers contribute under the garb of a school, downplaying their disagreements with their predecessors and often enveloping them within a commentary on a predecessor’s text, which is meant not just to explain it, but also to enfold all its potential meaning. Some scholars did move from one school to the other (e.g., possibly Vasubandhu or Maṇḍana), others just introduced in one school the elements of the other school they more strongly agreed with (e.g., Jayanta).

Key authors to be kept in mind:
• Dignāga (Buddhist epistemological school), introduced the threefold check, later accepted by all thinkers
• Kumārila (Mīmāṃsā), introduced the concept of intrinsic validity, explained that cognitions are not self-aware, challenged the Dignāga framework, systematised the discussions about absence and the other sources of knowledge (found already in his predecessor, Śabara).
• Dharmakīrti (Buddhist epistemological school), younger contemporary of Kumārila, adjusted the apoha theory and several other epistemological points in the light of Kumārila’s cricitism.
• Jayanta (Nyāya), modified the Nyāya epistemology in the light of Kumārila’s criticism, explained that cognitions are intrinsically doubtful, unless proven right, but that this does not lead to a paralysis, because one can act based on doubt.
