What is premise?

What Does premise Mean

Premise is a term originating from the Latin praemissus . The concept is used to name the clue , symptom or conjecture that allows us to infer something and draw a conclusion.

For logic and philosophy , therefore, the premises are those propositions that precede the conclusion . This means that said conclusion derives from the premises, although these may be true or false.
For example:
- Premise No. 1: "Human beings like the sea"

- Premise No. 2: "Facundo is a human being"

- Conclusion: "Facundo likes the sea"

As can be seen in the example, if human beings enjoy the sea and Facundo is a human being, it is possible to conclude that Facundo has to like it. Of course, the conclusion may be wrong since the first premise is not exact: there are people who do not like the sea .
In other cases, the premises may be true and yet the conclusion may be false:
- Premise No. 1: "Every Monday, Fernanda wakes up at 8 in the morning"

- Premise No. 2: "Today, Fernanda woke up at 8 in the morning"

- Conclusion: "Today is Monday"
In this example, the conclusion can be false even though the premises are true since the first premise is not exclusive. It may be true, therefore, that Fernanda wakes up every Monday at 8 in the morning, but she can also wake up at that time any other day of the week.
In colloquial language, finally, the idea of ​​premise is usually used as a synonym for principle (in the moral sense), value or objective : "The Catalan team always seeks victory based on the premise of control of the ball" , "We started the travel at dawn with the premise of arriving at your destination at lunch time ” .
Syllogism
A syllogism is called a form of deductive reasoning , that is, an argument in which the conclusion is obtained without exception from the premises. In this case, there are three propositions: two premises and the conclusion. The first to formulate a syllogism was the Greek philosopher and logician Aristotle in his work entitled " The Organon ", which can be translated as "the instrument."
According to Aristotle, logic is a relationship of terms , which are joined or divided in the judgments, and in his vision of the latter, a subject and a predicate also intervene. Although the concept of judgment is sometimes confused with that of proposition, there are clear differences: the former attributes a predicate to a logical subject and to the terms, a semantic and a syntactic function; the proposition, on the other hand, is a statement of a fact as logical content, making it a whole.

The terms of a judgment are related to each other and its comparison with one that could be considered means gives the possibility that the conclusions appear. In this way, the syllogism is composed of two judgments, the major and the minor premise, in which three terms are compared with each other and from there a new one is born, which is called a conclusion. The laws of logic attempt to ensure that the truth of the first three remains in the fourth.
The fundamental structure of a syllogism is as follows:
* Antecedent , consisting of the major premise (with the predicate of the conclusion, represented by the letter P) and the minor premise (the subject of the conclusion, represented by the letter S), which are compared taking into account the middle term , represented with the M;
* Consistent , which is the result of said comparison .
