Smoke and Fire. Sign Inference in Greek and in Indian Epistemology

Abstract

Abstract“Wherever there is smoke there must be fire.” In 1957, Aram M. Frenkian noticed that both ancient Greek and Indian philosophy makes use of the smoke-fire analogy as a model for inferential reasoning. He postulated that Greek use of the example reflected Indian influence on Greek philosophy which was mediated through the works of Pyrrho, the founder of Sceptisicm, who had accompanied Alexander the Great on his Indian campaign (327-5 BCE) and learnt from Indian sages (‘gymnosophists’ as the Greeks called them). More recent scholarship mainly shares his views. In the present paper, I argue that the smoke-fire example formed part of a complex theory of sign inference, and that not only the isolated analogy, but the theory as a whole which it illustrates is present in both cultures. Furthermore, the variants of this theory comprise such close and extended similarities that they must be the result of direct contact between Indian and Greek thinkers, although it is impossible to decide whether they stem from a common origin, or are the result of influence from one culture to the other.
