a study of the forms of cognitive activity. Logic changes together with changes in the forms of cognitive activity. Moreover, logic is not limited to theoretical forms of cognitive activity, but is also based on practical, experimental forms.

There are two main logical operations: 1) deduction, i.e. a general premise, a minor premise, and a conclusion. 2) Induction, i.e. a movement from plurality of concrete cases to a generalization. These two operations form one whole.
