Abstract
Among the means of valid cognition, the one which appears first in every enumeration, which was considered as being the basis of all other means of knowledge and which was considered as a legitimate method of knowledge by all schools of Indian thought is perception (pratyakṣa). With regard to perception, we can naturally expect such questions as ‘what is it to perceive’ or ‘what do we mean when we say that something is perceived’. It is generally believed that the philosophical theories of perceptions are really theories about what we mean by ordinary perceptual statements. In considering our knowledge about the external world, the philosopher tends to consider the way in which perception can and does provide us with the knowledge and the nature, extent and certainty of knowledge it provides us with. It is a well acknowledged fact that perception is the fundamental source of knowledge. In Buddhist epistemology, a systematic discussion on perception is found in the writings of Dignāga’s Pramāṇasamuccaya with vṛitti, who belongs to Yogācāra school of Buddhism of Mahayana tradition. An attempt has been made in this paper to explain and examine critically the first chapter of Pramāṇasamuccaya with vṛitti, i.e., perception with special reference to Non-Buddhist schools, namely Nyāyayikas, Vaiśeṣikas, Sāṁkhyans and Mīmāṁsakas. To explain it, the paper has been divided into three sections. Section I deals with Dignāga’s theory of perception and examination of non-Buddhist school's theory of perception, section II deals with Dignāga’s examination of nature of Perception with reference to non-Buddhists schools and section III deals with conclusion.
