According to the Buddhist concept of ‘dependent origination’ (pratītyasamutpāda), discrete factors come into existence because of a combination of causes (hetu) and conditions (pratyaya). Such discrete factors, further, are combinations of five aggregates (pañ caskandha) that, themselves, are subject to constant change. Discrete factors, therefore, lack a self-nature (ātman). The passing through time of discrete factors is characterized by the ‘characteristic marks of the conditioned’: birth (utpāda), change in continuance (sthityanyathātva), and passing away (vyaya); or, alternatively: birth (jāti), duration (sthiti), decay (jarā), and impermanence (anityatā). In the interpretation of the precise nature of these characteristic marks of the conditioned, and their relation to the discrete factor they characterize, different opinions were prevalent within the Sarvāstivāda School of Buddhist philosophy, with, judging from later scholastic literature, the views of the Dārṣṭāntika/Sautrāntika and the Vaibhāṣika sub-schools as most prominent ones. The Indian and Chinese Madhyamaka philosophers pointed to the fallacies in the Sarvāstivāda interpretations of the nature of the characteristic marks of the conditioned and their relation to the discrete factors they characterize, and, hence, to the fallacies in the Sarvāstivāda interpretations of the concepts ‘time’ and ‘temporality’.
