Scholars have characterized the Buddha and his doctrine in various ways. One such characterization, offered by Lambert Schmithausen, presents the Buddha as a “radical pragmatist” (radikaler Pragmatiker). I am referring to Schmithausen’s unpublished lecture draft on “Buddhistische Philosophie.” What Schmithausen underscores with this characterization is that the Buddha’s primary concern was not the theoretical-philosophical (das Theoretisch-Philosophische) but rather the spiritual-practical (das Spirituell-Praktische). The Buddha, to judge from early Buddhist sources, consistently and categorically rejected purely theoretical speculations as not only irrelevant but also detrimental to one’s salvific aspirations.
To be sure, Schmithausen does not, to my knowledge, employ the term “radical pragmatism” himself, though such a characterization may be justified—provided, of course, that it does not carry undesirable connotations and associations. One could characterize the Buddha’s radically pragmatic approach as “soteriopragmatism.” This term emphasizes the primacy of the spiritual-practical (das Spirituell-Praktische) as opposed to the theoretical-philosophical (das Theoretisch-Philosophische) aspect of Buddhist soteriology. In what follows, I have compiled secondary sources that characterize the Buddha's teaching as some form of pragmatism. As we shall see, pragmatism has also been attributed to Dharmakīrti and Candrakīrti.
Sullivan 1988: Religious Pragmatism (i.e., of Kumārajīva)
Kevin Sullivan, “Nāgārjuna’s Critique of Metaphysics.” De Philosophia 7, 1988, pp. 88–104 [not seen]. Ethan Mills in his “Nāgārjuna’s Scepticism about Philosophy” (In Buddhism and Scepticism: Historical, Philosophical, and Comparative Perspectives, edited by Oren Hanner. Hamburg Buddhist Studies. Bochum/Freiburg: projekt verlag, 2020, pp. 55–81 (p. 74) states: “Kevin Sullivan calls Kumārajīva’s attitude ‘religious pragmatism’ because the role of emptiness is purely soteriological rather than descriptive (Sullivan, 1988, pp. 98–100). Although Kumārajīva and Sengzhao may ultimately be mystics rather than sceptics, there is at least some affinity with my sceptical interpretation in their use of philosophical negation to cultivate stillness of mind.”
