Logical thinking refers to the way or form of connecting and organizing the content of thinking. Thinking takes concepts and categories as tools to reflect cognitive objects. These concepts and categories exist in the human brain in a certain frame form, that is, thinking structure. These frameworks can organize different categories and concepts together, thus forming a relatively complete train of thought, which can be understood and mastered to achieve the purpose of understanding. Therefore, thinking structure is not only a cognitive structure of human beings, but also a structure of human ability to grasp objects by using categories and concepts.

Social practice is the foundation of the formation and development of logical thinking. The need of social practice determines from which aspect people grasp the essence of things and determines the task and direction of logical thinking. The development of practice also deepens and develops logical thinking with the increase of perceptual experience. Logical thinking is the reflection of human brain's indirect generalization of objective things.

It reveals the essence of things with scientific abstraction, and has the characteristics of consciousness, process, indirectness and inevitability. The basic forms of logical thinking are concept, judgment and reasoning. The logical thinking methods mainly include induction and deduction, analysis and synthesis, and rising from concrete to abstract.
