Beyond the ascetic teaching and public manner of life later Cynic tradition remembers him for, Antisthenes was also a serious logician whose specific arguments Aristotle thought worth engaging directly. Antisthenes held that each thing can properly be described only by its own single, proper account, its own logos, and cannot correctly be said to be anything else, a position that ruled out ordinary predication, saying that a thing is good, or large, or a kind of something else, as strictly false or meaningless. Aristotle took this claim seriously enough to argue against it explicitly in his own logical works, treating Antisthenes's theory as a genuine rival account of definition and predication rather than a curiosity.
Ancient catalogues credit Antisthenes with an extensive body of writing, reportedly some ten volumes covering logic, ethics, rhetoric, and literary criticism among other subjects, a range that marks him as a systematic philosopher working across the standard divisions of the discipline rather than only a teacher of a single ascetic way of life. Almost none of that writing survives directly, and what is known of his specific positions, the theory of predication among them, comes chiefly through later philosophers who summarized or argued against him rather than through his own preserved text.
The Antisthenes who occupied Aristotle's attention as a logical opponent and the Antisthenes remembered as Cynicism's austere founding figure are the same man, but the first side of that reputation left far less trace in what actually survives.
