“I” ‘—this is precisely the point. The point is, moreover, that the human being needs this word, with its unique properties, to express what he experiences in relation to the outer world in a different way from an animal. Nothing is ascertained about the nature of the triangle by showing how the word ‘triangle’ evolved. No more can the nature of the I or ego be determined by anything that we may know as to how the use of the word ‘I’ arose from other usages of words in the evolution of language.
