Definition of affirmation - What it is, Meaning and Concept

Affirmation , from Latin affirmatio , is the action and effect of affirming or affirming .It is common for the term to be used in reference to an act that allows a person to express his assent to a statement or cause.For example: “With a gesture of affirmation, the respondent acknowledged that he knew the suspect ", " The woman's statement surprised the neighbors ", " I can't agree with a similar statement ".

The statement reflects an assent regarding a belief that is considered valid by evidence or certainties.It is possible to consider, in any case, different degrees or types of affirmation according to the awareness about the veracity of the statement.In this sense, the statements can be opinions , decisions , sentences , etc.

A police interrogation what s and develops in search of the answers of a suspect to solve a murder case can lead to affirmations and denials.If the questioner is asked if he was at the scene of the crime and he says no, he will have made a denial of the accusation.change, if asked about whether it is true that he works as a mechanic in a workshop and the person replies that yes, he will have given his statement to that question.

Affirmations can be associated, in a way, with everything said by a person.After all, what is put into words is an extension of what the subject thinks.Expressions like "In my opinion, the opposition candidate must give up his candidacy" , "Garlic chicken is my favorite food" and "I left my house at eight in the morning and I could just get on the train at a quarter to eleven ” are statements made by an individual.

But the nature of an affirmation is not always the foundation, since for various cultural reasons human beings are accustomed to repeating data that we have acquired passively, without analyzing its truthfulness, without contrasting its sources.One of the fields in which there is more lack of theoretical support is health: we are all able to describe the characteristics of a cold, from the reasons why it appears until its evolution and the methods of fighting it, but almost no one has technical knowledge or studies with whom you can defend this information.

This does not mean that a large percentage of people lie on a daily basis, but that the meaning of the word affirmation is broad, and that it depends on the context in which it is used.In addition, affirming something false believing that it is true cannot be called a lie but, in any case, negligence.

Logical equivalences

It is known by the name of logical equivalence to a similarity as to the truth that exists between two or more expressions, as long as any of them is valid.In other words, to confirm a given case you can take an affirmation or another of the group without affecting the final result.The most used method to demonstrate equivalences is that of the truth table.

As easy as it may seem to analyze the veracity of an affirmation in everyday life, the logic reaches beyond the simple verification we can perform on a day-to-day basis, and breaks down each expression into parts, studies the way in which they relate and treat them as if they were mathematical equations, so that a demonstration of equivalence yields results impossible to refute.

In the declarative algebra, also called propositional, the logical expressions are manipulated through variables and constants to represent the truth values, and there are various schemes that serve to solve the equivalences, as if they were mathematical properties that help to clear unknowns from an equation.
