Read and discuss a lot. Preferably at various scientific seminars with aggressive opponents. So quickly learn to support each statement with facts, to be logical and consistent in your judgments. And then the skill will pass into normal life.

First you need to decide on the logic. Most often, this word is understood as either Formal Logic (Aristotle) or Dialectical Logic (Hegel).

Formal logic is more or less known to everyone and is studied starting from school. It can be expressed in three laws::

* the law of identity — the concept must be used in the same sense in the course of reasoning; or A = A

* the law of contradiction — two incompatible (contradictory) propositions cannot be simultaneously true; either A or not-A

* the law of excluded third-A or not-A true, no third given

Dialectical logic is not easy for an untrained person to understand, because it “violates” the laws of formal logic, while using it to “derive” categories. If in formal logic everything is linear and consistent (for example, the application in mathematics), then dialectics tells us that everything is contradictory, both A and non-A are true at the same time, and we must take “both sides of the coin”.

For example, after considering the concept of “change” and trying to describe it dialectically, we are forced to recognize that change is both equality and inequality with ourselves. Thequestion.ru Ivanov, who learned something new, remained himself (Ivanov), but at the same time became not equal to himself in connection with the acquisition of new knowledge. One side is wrong to consider, because it does not reflect the truth. If he remains the same and is only equal to himself, then where did the new knowledge go, did it not change him? If he is only unequal to himself, then it would be good for him to hand over his passport, because he is no longer Ivanov and it is somehow ugly to use other people's documents.

I advise you to go deeper into the study of dialectics (“The Science of Logic”, G. Hegel) and you will begin to see things from a different angle, a lot will clear up in your head.�

An example of the application of dialectical logic in practice is Karl Marx's work “Capital”, so if you want to move forward in logic, then you should pay attention to the works of geniuses, and not waste your time on crosswords, chess and empty discussions.
