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.
An argument by example (also known as argument from example) is an argument in which a claim is supported by providing examples. Most conclusions drawn in surveys and carefully controlled experiments are arguments by example and generalization.
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 ...
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.
For example, inferring the conclusion "no cats are frogs" from the premises "all frogs are amphibians" and "no cats are amphibians" is a sound argument. But even arguments with false premises can be deductively valid, like inferring that "no cats are frogs" from the premises "all frogs are mammals" and "no cats are mammals".
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 ...
The purpose of argumentation (also called persuasive writing) is to prove the validity of an idea, or point of view, by presenting sound reasoning, discussion, and argument to thoroughly convince the reader. Persuasive writing/persuasion is a type of argumentation with the additional aim to urge the reader to take some form of action.
The logic of argumentation (LA) is a formalised description of the ways in which humans reason and argue about propositions. It is used, for example, in computer artificial intelligence systems in the fields of medical diagnosis and prognosis, and research chemistry.
