in theoretical matters, rhetorical methods are required in practical matters such as adjudicating somebody's guilt or innocence when charged in a court of law, or adjudicating a prudent course of action to be taken in a deliberative assembly. The core features of dialectic include the absence of determined subject matter, its elaboration on earlier empirical practice, the explication of its aims, the type of utility and the definition of the proper function. For Plato and Aristotle, dialectic involves persuasion, so when Aristotle says that rhetoric is the antistrophe of dialectic, he means that rhetoric as he uses the term has a domain or scope of application that is parallel to, but different from, the domain or scope of application of dialectic. In Nietzsche Humanist (1998: 129), Claude Pavur explains that "[t]he Greek prefix 'anti' does not merely designate opposition, but it can also mean 'in place of.'" When Aristotle characterizes rhetoric as the antistrophe of dialectic, he no doubt means that rhetoric is used in place of dialectic when we are discussing civic issues in a court of law or in a legislative assembly. The domain of rhetoric is civic affairs and practical decision making in civic affairs, not theoretical considerations of operational definitions of terms and clarification of thought. These, for him, are in the domain of dialectic. Aristotle's treatise on rhetoric systematically describes civic rhetoric as a human art or skill (techne). It is more of an objective theory than it is an interpretive theory with a rhetorical tradition. Aristotle's art of rhetoric emphasizes persuasion as the purpose of rhetoric. His definition of rhetoric as "the faculty of observing in any given case the available means of persuasion", essentially a mode of discovery, limits the art to the inventional process, and Aristotle heavily emphasizes the logical aspect of this process. In his account, rhetoric is the art of discovering all available means of persuasion. A speaker supports the probability of a message by logical, ethical, and emotional proofs. Some form of logos, ethos, and pathos is present in every possible public presentation that exists. But the treatise in fact also discusses not only elements of style and (briefly) delivery, but also emotional appeals (pathos) and characterological appeals (ethos). Aristotle identifies three steps or "offices" of rhetoric—invention, arrangement, and style—and three different types of rhetorical proof: ethos (Aristotle's theory of character and how the character and credibility of a
