What is thinking? Sketches

It would be naive to believe that we can give a satisfactory definition of the concept of "thinking". In pursuit of him, at best we formulate an impractical idea of ​​thinking. We need a tool, more precisely - an instruction for the tool that we already have, but we do not quite understand how to use it.
Without this instruction, our thinking (as a tool) itself is not yet thinking in the strict sense of the word. So, this instruction is not just the rules for using thinking. It should create thinking as a tool, give thinking the status of thinking. As a result, we will get not even one thinking, but several different types of it. We have to understand how something that should be called thinking can work in different modes.
