  Proponents of the NRNB view take the argument of Plutarch to give a general theory of action that supports universal suspension of judgment as a natural reaction to equally balanced arguments. On this theory all actions are merely impulsive, i.e., caused just by impressions of what appears suitable (‘oikeion’). Since the skeptic doesn’t make judgments, the only sense in which she is committed to her impressions is that she acts on them. It is unclear how this is compatible with the evidence of Sextus on ‘the reasonable’, where the skeptic considers reasonable justifications in deciding what to do. But some advocates of NRNB combine the two so that a class of impulsive actions count as voluntary if, after their performance, one can reasonably justify them as successful (e.g., Ioppolo 1981; 1986; 2000).
