 Cicero refers to Pyrrho about ten times, and Cicero is, in general, a responsible reporter of other people’s views. Unfortunately his information about Pyrrho appears to be very incomplete, and, as we shall see, the impression he conveys of him may very well be inaccurate. With one exception, he never mentions him except in conjunction with the famously non-orthodox Stoics Aristo and (sometimes) Herillus, and the remarks in question always concern the same one or two points in ethics; it looks as if his knowledge of Pyrrho derives almost entirely from a single source that conveyed little or nothing about Pyrrho individually. In addition, a number of authors in later antiquity make isolated comments about Pyrrho. But since these comments postdate the rise of the later Pyrrhonist movement, there is often room for suspicion as to whether they reflect genuine information about Pyrrho himself, as opposed to the later philosophy that took his name.
