What are the three argument types?

Answer 1

The three argument types are deductive, inductive, and presumptive. Their differences are based on the strictness of the connection of the premises to the conclusion.

Deductive: In a valid deductive argument, if the premises are true, by logical necessity, the conclusion must be true. There is a strict link between the premises and the conclusion. It is logically impossible for the premises to be true and the conclusion false. There are multiple types of deductive arguments shown in the related question below.

Inductive: Not such a strict link between premises and the conclusion. Inductive is usually based on probability (and therefore may contain statistics and percentages). So if the premises are true, the conclusion is probably true. Keywords in an inductive argument include some, most, usually, typically, and other words that suggest that not all things mentioned in the premises are or do what is suggested. It is pretty much a yes or no argument, either deductively valid or not.

Presumptive: In this case, the presumption is based on probability, it is tentatively acceptable if the premises are true. This type of argument is usually used when there is no evidence suggesting the contrary, in which case the argument would be proved wrong.

Answer 2

The three argument types are ethos, logos, and pathos. Ethos refers to establishing credibility and trustworthiness, logos involves using logic and reasoning to persuade, and pathos involves appealing to emotions to make a connection with the audience.
