Something relevant is important or significant.
Relevant has its origin in the Latin word relevans which, in turn, comes from relevare ( "to raise" , "to raise" ). It is something significant , important , outstanding or outstanding .
For example: "The rise in prices is not a relevant problem for the company" , "Deportivo San Juan has hired Ramiro López Pereyra, a player who will be relevant to the new structure of the team" , "The absence of deputy Pichot "It was the most relevant news of the opposition meeting," "I ask you not to come into my office to tell me that nonsense: only interrupt me if you have something relevant to tell me."
What is relevant acquires its meaning only in comparison with other things. For something to be relevant, it is essential to draw parallels with other things that are part of a hypothetical list of priorities, categories or hierarchies . Relevance also depends on each person .
What is relevant, the result of a comparison
Buying a car can be a major project in an individual's life. However, if said subject equates the possibility of purchasing a car with the intention of buying a house, the second option may be more relevant. Therefore, the purchase of the car loses importance and is relegated.
A power outage in a building is a problem that has different relevance for each neighbor. Those who live on the first floor will surely not suffer as many problems as those who live on the twentieth floor. For these people who must go up or down twenty flights of stairs because the elevator does not work, the interruption of electrical service is a relevant disorder.
In the business world it is essential to maintain relevance over the years, trying to renew oneself so as not to get lost in the sea of competitive offers . International companies work hard to ensure that their products are perceived as necessary goods in the lives of their potential consumers, and this entails a series of studies from different fields, such as sociology and marketing, and a constant updating of advertising campaigns. .
What is relevant is differentiated from the rest by some particularity or characteristic.
A theoretical contribution from the philosopher Iván Orlov
Relevant or relevance logic is called logic that belongs to one of the families considered non-classical substructural that imposes a certain number of restrictions for its involvement. Its creator was Iván Orlov , a philosopher from Russia , born in 1886 ; proposed the existence of the relevant logic in his mathematical publication entitled " The Logic of the Compatibility of Propositions ."
Relevance logic focuses on those points of the implication that the operator of the material conditional ignores , according to classical truth-functional logic. This was not an unprecedented observation, since an American philosopher named Clarence Irving Lewis had previously proposed the strict conditional , a material conditional on which a necessity operator acts (if for propositions materially implies Y, then X strictly implies Y).
This gave rise to certain paradoxes , such as the one seen below: "If I am a human being, then the Earth is cubic"; Even if the first proposition is fulfilled, the planet will not change its shape.
Differences between relevant and classical logic
Fundamentally, relevant logic is distinguished from classical logic in that it requires that there be a relevant relationship between the antecedent and the consequent of an implication. When operating with propositions it is necessary that the atomic formulas of the premises and conclusions are the same, although this does not indicate that there is sufficient relevance.
When performing a predicative calculation, it is requested that the premises and conclusion have the same variables and constants. To ensure compliance with this condition, it is possible to place some restrictions on the regulation of the natural deduction system (a procedure that attempts to reproduce people's natural way of reasoning when they construct mathematical demonstrations).
