The aim of this essay is tho show the source of the knowledge of 'myself'. How do we know ourselves? The negative answer sounds: we do not know that on the basis of private experience. The way to know our 'own' psychological content runs round about: it goes through the other people. To know that I think, feel pain, or hope we have to know that other people think, feel pain, or hope. The place we find ourselves is the place of finding others. The source of understanding what is thinking, feeling - is primitive reactions, which include the other people as well.
