Logic is the main instrument of interaction between the individual and the environment. It is thanks to logic that a person is able to realize his own mistakes, analyze them and give an adequate assessment of his actions and the environment.

Often, in the second year of university, logic is presented in the form of a pun that most people can understand.

However, logic is not only about understanding someone else’s irony or exposing the surrounding reality with one’s irony. This is the ability to self-criticize and control one’s behavior in critical situations.

Of course, logic can be developed by playing chess or solving crossword puzzles, but without practical application, many theorists are doomed to make mistakes.

So, from a purely scientific point of view, universities distinguish the following laws of logic:

1. The law of the exclusive third – two contradictory propositions cannot both be false, one of them will be true: “a” is either “b” or not “b”.

2. The law of identity is the principle of constancy or preservation of the objective meaning of judgments or semantics in some obviously known or implied context.
