Pyrrho of Elis went with Alexander the Great to Central Asia and India during the Greek invasion and conquest of the Persian Empire in 334-324 BC. There he met with early Buddhist masters. Greek Buddha shows how their Early Buddhism shaped the philosophy of Pyrrho, the famous founder of Pyrrhonian scepticism in ancient Greece.

Christopher I. Beckwith traces the origins of a major tradition in Western philosophy to Gandhara, a country in Central Asia and northwestern India. He systematically examines the teachings and practices of Pyrrho and of Early Buddhism, including those preserved in testimonies by and about Pyrrho, in the report on Indian philosophy two decades later by the Seleucid ambassador Megasthenes, in the first-person edicts by the Indian king Devanampriya Priyadarsi referring to a popular variety of the Dharma in the early third century BC, and in Taoist echoes of Gautama's Dharma in Warring States China. Beckwith demonstrates how the teachings of Pyrrho agree closely with those of the Buddha Sakyamuni, "the Scythian Sage." In the process, he identifies eight distinct philosophical schools in ancient northwestern India and Central Asia, including Early Zoroastrianism, Early Brahmanism, and several forms of Early Buddhism. He then shows the influence that Pyrrho's brand of scepticism had on the evolution of Western thought, first in Antiquity, and later, during the Enlightenment, on the great philosopher and self-proclaimed Pyrrhonian, David Hume.

Greek Buddha demonstrates that through Pyrrho, Early Buddhist thought had a major impact on Western philosophy.

公元前334-324年希腊入侵和征服波斯帝国期间，埃利斯的皮罗随亚历山大大帝去了中亚和印度。在那里他遇到了早期的佛教大师。希腊佛陀》展示了他们的早期佛教如何塑造了古希腊著名的皮尔洛怀疑论创始人皮尔洛的哲学。

克里斯托弗-I-贝克维思(Christopher I. Beckwith)将西方哲学的一个主要传统追溯到犍陀罗，一个位于中亚和印度西北部的国家。他系统地研究了皮罗的教义和实践以及早期佛教的教义和实践，包括那些保存在皮罗的证词和关于皮罗的证词中，保存在20年后塞琉西王朝大使梅加斯特尼关于印度哲学的报告中，保存在印度国王德瓦南普利耶-普里亚达西的第一人称诏书中，提及公元前三世纪初流行的各种佛法，以及保存在战国中国的道家对鸠摩罗什佛法的呼应。Beckwith证明了Pyrrho的教义如何与佛祖释迦牟尼（"斯基泰圣人"）的教义密切一致。在这个过程中，他确定了古代印度西北部和中亚的八个不同的哲学流派，包括早期拜火教、早期婆罗门教和早期佛教的几种形式。然后，他展示了皮罗的怀疑论品牌对西方思想演变的影响，首先是在古代，后来在启蒙运动期间，对伟大的哲学家和自称是皮罗主义者的大卫-休谟产生了影响。

希腊佛》表明，通过皮尔洛，早期佛教思想对西方哲学产生了重大影响。
