As in this example, argumentation schemes typically recognize a variety of semantic (or substantive) relations that inference rules in classical logic ignore. [2]: 19 More than one argumentation scheme may apply to the same argument; in this example, the more complex abductive argumentation scheme may also apply.
Argumentation schemes are stereotypical patterns of inference, combining semantic-ontological relations with types of reasoning and logical axioms and representing the abstract structure of the most common types of natural arguments. [13] A typical example is the argument from expert opinion, shown below, which has two premises and a conclusion ...
Of the many and varied argument forms that can possibly be constructed, only very few are valid argument forms. In order to evaluate these forms, statements are put into logical form . Logical form replaces any sentences or ideas with letters to remove any bias from content and allow one to evaluate the argument without any bias due to its ...
Two men argue at a political protest in New York City. Example of an early argument map, from Richard Whately's Elements of Logic (1852 edition). Argumentation theory is the interdisciplinary study of how conclusions can be supported or undermined by premises through logical reasoning.
Argumentation theorists have identified two kinds of practical reasoning: instrumental practical reasoning that does not explicitly take values into account, [2] and value-based practical reasoning. [3] The following argumentation scheme for instrumental practical reasoning is given in Walton, Reed & Macagno (2008).
The pragma-dialectical theory has been applied to understand several different types of argumentative discourse. For example, it has been used to analyze and evaluate legal argumentation, mediation, negotiation, (parliamentary) debate, interpersonal argumentation, political argumentation, health communication and visual argumentation.

Later writers on rhetoric, such as Cicero and Quintilian, refined this organizational scheme, so that there were eventually six parts: the introduction, or exordium. In the exordium, the speaker gives their main argument, and all relevant information. the statement of the case, or narratio. Quintilian explained that in the narratio "we shall ...
For example, if a presidential candidate has a long history of philanthropy, he or she will invent an argument that demonstrates personal good character in order to convince the audience that he or she is the best candidate for office. Pathos represents an appeal to the audience's emotions. [10]
