Hajime Nakamura in his A Comparative History of Ideas. London / New York: Kegan Paul International, 1986 [Revised Edition of Tokyo 1975] devotes a section with the title “The Seeking of Dishonor.” For the context, I cite the following two paragraphs (p. 180):
Cynicism appeared in Athens about the beginning of the fourth century B.C. Although the ethical teachings of Cynicism owed much to Antisthenes (c. 446–366 B.C.), it was Diogenes of Sinope (404–323 B.C.) who was first called kyon, the dog, from which the name ‘Cynicism’ derives. The popular sermons of the Cynics exerted considerable influence in the days of the Roman Empire until the fifth century A.D.
Antisthenes derived his form of Cynicism from a particularized interpretation of some of Socrates’ doctrines. Socrates, we may recall, sought to keep his independence from physical wealth and mass popularity so that he could more freely pursue what he considered to be the higher good of wisdom (sophia). For Antisthenes, independence itself was embraced as wisdom or the true good. Self-sufficiency or independence from earthly possessions and pleasures became for him an end in itself.
In the Indian context, Nakamura mentions, among others, the Pāśupatas of Śaivism as a point of comparison.
And then, he states (p. 182):
Han-shan (Kanzan) and Shih-te (Jittoku), Chinese counterparts of the Cynics and Pāśupatas, were recluses in the Tang period. Han-shan lived in caves and on rocks and Shih-te lived in the precincts of a certain temple. When Han-shan came, Shih-te gave him the remaining scraps of meals forsaken by temple monks. They were wont to suddenly shout or revile towards the sky. They wore ragged clothes and acted like mad persons. When a high official came to see them they departed, sending a smile to him in arrogance. It is said that they indulged in gaily sweeping away moonbeams, when they were not telling each other Zen jokes. They were regarded as the ideal of idiot sages. Han-shan, Shih-te and their admirers did not deliberately seek for dishonor, although when it came their way they did not resist it.
In addition, we may claim that a form of Buddhist cynicism, or cynicism in Buddhism, can be found in the Mahāsiddha tradition in India and the “mad masters” (bla ma smyon pa, a neologism) tradition in the Tibetan cultural sphere. Some doctrinal seeds of Buddhist cynicism, or cynicism in Buddhism, may be traced in Vinaya asceticism and in Mahāyoga Tantricism. The idea of unmattavrata (smyon pa brtul zhugs kyi spyod pa) would be relevant here. The idea of sanity and insanity in Buddhism is, in itself, a fascinating topic. If we consider the life of dPal-sprul (1808–1887), who, by the way, called himself an “old dog” (khyi rgan), he can be considered a “Buddhist cynic,” and his approach in and attitude to life may be characterized as a form of “Buddhist cynicism.”
