A analog argument, by analogy or comparative argument is a type of inductive argumentation in which perceived similutes are used to explain other similarities that have not yet been observed.
Not all analogies are arguments, however, they are usually used to illustrate a belief within a speech. The analogical argument is built on the premise that all the elements compared have something in common.
This does not mean that it can cover all the elements, but it can establish similarities between some properties of them.
For this reason, analog arguments are also called comparative arguments, since they use the reasoning of previous or similar situations of relative validity to make comparisons between elements that share one or more characteristics..
This is how all analog arguments have the same structure, they speak of the same property or properties of one or more elements..
Its truth or falsehood can be appealable since its validity is always relative and will depend on the logic of those who establish and evaluate it..
Analog arguments have the following structure:
Two or more individuals share the same properties a and b. Most of these individuals also share the properties c and d. Therefore, the minority of these individuals must also share the properties c and d.
