The <i>Nun</i> in the <i>Parmenides</i>: Not Another <i>Exaiphnês</i>

Abstract After some preliminary remarks about Plato’s use of the adverb nun , I explain what the nun is by offering a close textual analysis of the key passage in which it is explicitly addressed ( Parm . 151e3–153b7). Its metaxu nature, between duration and limit, requires one to consider another temporal notion of the second part of the Parmenides that is metaxu , namely the exaiphnês . I explain why the nun does not conceptually overlap with the exaiphnês , arguing moreover that there is no model where both notions fit, but rather a model accounting for a switch and another one accounting for continuous change.
