Yes. I was first introduced to Pyrrhonism via Adrian Kuzminski’s
Pyrrhonism: How the Ancient Greeks Reinvented Buddhism. I also read Christopher Beckwith’s
The Greek Buddha (which is more an attempt to show that Pyrrho probably derived his philosophy from encounters with Indian Buddhists – via historical/linguistic sources – than a thorough discussion of the philosophy).
The word
samadhi seems to have many different translations/interpretations (some of which seem hardly related to one another at all), but “In the oldest Buddhist suttas, on which several contemporary western Theravada teachers rely, it refers to the development of
a luminous mind which is equanimous and mindful.” [Wiki] That, too, would seem akin to the definition that FMF provided for ataraxia, and what Kuzminksi and other neo-Pyrrhonians talk about.
Nirvana often implies, I think, the extinction of all desires – as well as a state of nondual awareness. I don’t think that ataraxia necessarily carries those implications. But, again, many interpretations which can make exact cross-language comparisons difficult. (Other interpretations of samadhi would also seem problematic to me.)
Kuzminksi seems to allow either nirvana or samadhi as quasi-synonyms for ataraxia. Beckwith mentions only nirvana as equivalent to ataraxia. But he also translates Pyrrho’s follower Timon as saying that ataraxia must be preceded by
apatheia: “lack of passion/emotion.” But apatheia often meant freedom just from negative or deleterious/distressing passions (pathe) – such as anxiety – but not from the
eupathe: “good or happy passions” –such as cheerfulness. That is the way the Stoics used the term, not as a lack of all feeling or emotion, nor as indifference (a lack of interest or concern) – as with our modern definitions of apathy.
I’ve started a reading paper relating Pyrrhonism to Zen Buddhism. Will take me awhile to wade through it.
