An introduction of the three types of rhetoric (forensic, deliberative, and epideictic) occurs in Book I Chapter III of Aristotle's
On Rhetoric. Discussion of forensic rhetoric is found in Book I, Chapters X–XV, outlined as follows: • Chapter 10: "Topics about
Wrongdoing" asserts: "Let wrongdoing be defined as doing harm willingly in contravention of the law." Aristotle also defines three considerations of forensic rhetoric: 1. For what purposes persons do wrong 2. How these persons are mentally disposed 3. What kind of persons they wrong and what these persons are like. • Chapter 11: "Topics about Pleasure" categorizes pleasure as natural, not compulsive, and can be the cause of crime: gaining revenge, winning, or restoring honor. • Chapter 12: "Topics about Wrongdoers and Those Wronged" includes many features of both the wrongdoers and the wronged that relate to criminalities: • Wrongdoers: believe they will not be detected or punished, are likely to go unsuspected if their appearance is inconsistent with the charges (a weak man charged with assault), have either no enemy or many enemies. • Those who are wronged: have something the wrongdoer lacks, do not live cautiously, have never been wronged, or have been often wronged with no retaliation. • Chapter 13: "Topics about
Justice and
Injustice" discusses the
law in two ways: specific (that which has been defined for each person) and common (that which is based on nature or common principle). • Chapter 14: "The Koinon of Degree of Magnitude" proposes: "A wrong is greater insofar as it is caused by greater injustice. Thus the least wrong can sometimes be the greatest." Aristotle asserts that varying degrees of wrong exist based on the accessibility of retribution from the wronged and
punishment for the wrongdoer. • Chapter 15: "Atechnic Pisteis in Judicial Rhetoric: Laws, Witnesses, Contracts, Tortures, Oaths" summarizes the objects listed in its title, including evidence that supports or refutes a case. These summaries and guidelines are very practical in law both in Aristotle's and in modern times. Aristotle also focuses on fairness and introduces the possibility that the
defendant could be legally guilty yet morally justified. ==Early connection between law and rhetoric==
