In this paper I will focus on Antisthenes’ theory of unique enunciation, and will then discuss its similarities and differences with, and/or possible influences on, other theories on language that flourished around the 4th and 3rd centuries BCE. I showed elsewhere that Antisthenes’ theory of language is a practical application or a strategy that has direct implication for his ethical project. My aim here is merely to highlight the originality and relevance of Antisthenes’ theory by presenting it and contextualizing it, before assessing relevant similarities and differences between certain positions of Antisthenes and those of some Skeptics, Sophists, Cyrenaics, and Megarians
