 Theophrastus closely followed Aristotle in distinguishing between deliberative, judicial and epideictic rhetoric, as well as in dividing a speech into parts (fr. 671 FHS&amp;G). He also distinguished between audience-oriented speech and fact-oriented speech; the former is illustrated by poetry and rhetoric, which are characterized by their ornamented style, while the latter is illustrated by philosophy, which is concerned with truth and methods of argument (fr. 78 FHS&amp;G). Although the originality of this classification and his acceptance of the legitimacy of affective prose may be limited to a simple modification of Aristotle’s views, Theophrastus thus managed to eliminate the last traces of Plato’s hostility to rhetoric. In his treatise On Style, on the other hand, he seems to have tried to improve over the Aristotelian tripartite division of good style into clarity, appropriateness and ornamentation (Rhetoric 3.2–12), by adding a fourth virtue of speech, namely that of speaking correct Greek (hellenismos), which he places before the others; it is likely that his interest in it reflects the development at the time of grammar as an independent subject. So, it is the combination of precisely these four qualities that is meant, according to Theophrastus, to achieve in style the desired mean, which he also advocated in diction, rhythm and sentence structure (see Innes 1985).
