Logical Inference Example

The logical inference it is a limited process of reasoning, procedural inference, which is based on a precedent as the basis for a final conclusion.

Logically, the initial idea establishes the direction to be followed, consisting of a series of ordered steps that we will explain here:

1. The inference establishes that to reach a conclusion you must have a certain order: A, B, C, and if this order is altered you can reach a wrong conclusion.
2. It is the mind that establishes the logical evaluation of the concepts, which allow you to reach a conclusion.
3. Depending on the order or placement, these ideas can provoke thoughts that, although they can be linked, can lead to a different conclusion than what was initially expected.

It should be clarified that the initial premise can be false, giving a complete logical inference but with a false conclusion

It is therefore that in this type of reasoning the veracity must be verified by means of a complete syllogism, which is separated from the basic logical inference.

Remaining clearly that logical inference is a formal reasoning that is not based on the objective but on the relationship of the premises.

Inference representation

Inferences are described by symbols. The initial premises are marked with the letter P the secondary premises with the letter what and the conclusion with the three-point symbol (.·.)

Example of logical inference:

Logical inference with true base

1. Men die = premise 1 = p
2. Ernesto is a man = premise 2 = q
3. Therefore Ernesto dies = conclusion =. ·.

1. All math books are boring
2. This is a math book
3. This is a boring book

1. The children grow up
2. Ana is a girl
3. Ana will grow

1. Who works wins
2. I work
3. Therefore I win something

Logical inference with false initial premise

1. Cats fly
2. This is a cat
3. This cat can fly

1. Pigs sweat
2. Chocho is a pig
3. Pussy sweats a lot
