The word 'sceptic' usually refers to a theoretical figure whose philosophical importance lies exclusively in his challenge to any attempt to justify the belief in the possibility of knowledge. But the label was once applied to living persons - the so-called Pyrrhonists - whose scepticism encompassed a way of life. Following Sextus Empiricus's portrayal of the Pyrrhonists, Arne Naess has provided comprehensive arguments both in rebuttal of the frequent claims either that scepticism is logically inconsistent or that at least it is impossible to put into practice, and in support of scepticism as a fruitful philosophical attitude. The present essay attempts a critical consolidation of Naess's case for scepticism by drawing more explicitly than he does on his work in empirical semantics. The notion of degrees of preciseness is used to outline a philosophically interesting rationale for the Pyrrhonist's persistent abstention from any act or action that commits him to the truth of a proposition, and also to indicate why possible, or even inevitable lapses on the Pyrrhonist's part need not seriously prejudice either his status as a sceptic or the philosophical value of his sceptical ideal.

: The question of possible Indian influence on Pyrrhonist skepticism was raised long ago by Diogenes Laertius in his biography of Pyrrho. Diogenes tells us that Pyrrho adopted his "most noble philosophy" as a result of his contacts with Indian sages when he accompanied Alexander the Great on his expedition in the fourth century B.C.E. Most modern Western scholars have downplayed Diogenes’ claim as unsubstantiated, but the striking parallels to be found in subsequent ancient Pyrrhonist and Mādhyamaka texts suggest its continued plausibility. In both the Pyrrhonist texts of Sextus Empiricus and the Mādhyamaka texts of Nāgārjuna and Candrakīrti, we are repeatedly counseled above all to suspend our various non-evident beliefs, that is, our judgments about or attachments to evident things, if we wish to be liberated from the anxiety that such beliefs create and gain some kind of tranquillity, bliss, or enlightenment. A comparative analysis of these Pyrrhonist and Mādhyamaka texts finds that what differences exist are entirely compatible with, and equally in the service of, this common, and indeed virtually identical, therapeutic purpose. It is perhaps not too much to say that Pyrrhonism and the Mādhyamaka are nearly indistinguishable from one another, an intriguing conclusion to contemplate.

The purpose of the present paper is twofold. First, to examine what beliefs, if any, underlie (a) the Pyrrhonist’s desire for ataraxia and his account of how this state may be attained, and (b) his philanthropic therapy, which seeks to induce, by argument, ejpochv and ataraxia in the Dogmatists. Second, to determine whether the Pyrrhonist’s philanthropy and his search for and attainment of ataraxia are, as scholars have generally believed, essential aspects of his stance.

By far the most detailed surviving examination by any ancient Greek sceptic of epistemology and logic, this work critically reviews the pretensions of non-sceptical philosophers, to have discovered methods for determining the truth, either through direct observation or by inference from the observed to the unobserved. A fine example of the Pyrrhonist sceptical method at work, it also provides extensive information about the ideas of other Greek thinkers, which in many instances, are poorly preserved in other sources.
