The idea is introduced as follows:

Thinking is initially a process of generalization and indirect reaction of human brain to things by means of language. Thinking is based on perception and transcends the boundaries of perception. Thinking in the usual sense involves all cognitive or intellectual activities. It explores and discovers the intrinsic relationship and regularity of things, which is an advanced stage of cognitive process.

The indirect reflection of thinking on things means that it understands objective things through other media and infers unknown things with the help of existing knowledge, experience and known conditions. The commonness of thinking lies in its rejection of the non-essential attributes of a class of things and its reflection of the same essential characteristics.

With the deepening of research, people find that besides logical thinking, there are also thinking forms such as image thinking and epiphany thinking. Logical thinking is also called abstract thinking, image thinking is also called image thinking, and insight thinking is also called inspiration thinking.

The analysis of thinking is as follows:

It is the most basic thinking activity. Analysis refers to the process of decomposing the whole thing into its components in your mind, or the process of decomposing individual characteristics and aspects in the whole; Synthesis refers to the process of connecting all the components of an object in mind, or combining all the characteristics and aspects of things into a whole.

Analysis and synthesis are two inseparable aspects in the same thinking process, which are both opposite and closely related. Without analysis, people can't clearly understand objective things, and all kinds of objects will become general and vague; Without synthesis, people's understanding of various parts of objective things, individual characteristics and other organic components is one-sided, and they cannot fully understand things from the organic components of the object.

The comparison of thinking is as follows:

Comparison is the thinking process of determining the similarities and differences between objects in your mind. Classification is a way of thinking that classifies things into different categories according to their similarities and differences. Comparison is the basis of classification. Comparison is of great significance for understanding objective things. Only through comparison can we confirm the primary and secondary characteristics, similarities and differences of things.
