Lectures on Categories

This paper will address the question whether and to what extent the ontological categories of early Indian philosophies can be looked upon as what might be called ‘natural categories’, categories that correspond in some way to the reality they intend to describe. It turns out that some of the Indian categories are of this kind, others are not. Examples will be discussed.

This paper examines Nyaya's understanding of the sources of knowledge, especially perception and inference, as generating genuine subkinds of cognition that are discernible by introspection as well as through our own and others' behaviour, and addresses how typological resources are used by the school in its epistemological theory. By being able to recognize a cognition as perceptual, inferential, analogical, or testimonial in character, we have access to our knowledge such that doubt and controversy can be resolved. The hinge premise is that we may assume such cognition to be veridical. Like contemporary disjunctivists, Naiyayikas see pramana as natural processes and their results as falling into natural kinds, with close imitators, illusions, incorrect inferences, false testimonial comprehension, and so on, as something else altogether, not the same at all, though a wider uniting kind may be identified, being-a-property, being-a-psychological-property, and so on up through the categorial system. This facet of Nyaya's epistemology helps to solve an issue facing modern reliabilist externalism, which is the position that beliefs receive a default positive epistemic status in virtue of being the results of reliable processes of belief-formation. The issue is how to differentiate doxastic processes in an epistemically relevant fashion. Nyaya has a straightforward answer--identify candidates by the highest standard, one-hundred percent reliability, and correlating marks (jati-vyanjana)--an answer that this paper in the end says a word or two to defend.

The status of categories within Madhyamaka philosophy is a curious one. On the one hand there is a strong tendency to reject philosophically refined analyses of the constituents which make up the world, thereby rejecting systems of categories as well. The Madhyamika, it seems, accepts whatever conventions the world accepts at the merely conventional level but does not propose any conventions of his own. In fact there appear to be good reasons for such a view. Given that the membership of an object in a category is generally taken to be a clear example of a property an object has intrinsically, and since the Madhyamikas reject intrinsic properties (properties which exist by svabhava) they should reject categories as well.

This paper explores the shift in Jaina thought from categorization (the ontological dualism of jiva and ajiva) to classification (the universe as a map of the Jina's mind), and reflects on a corresponding alteration in soteriological and sociological concerns.
