What is unique about the "I" hides itself exactly in what is unimaginable about a person. All we are able to imagine is what makes everyone like everyone else, what people have in common. The individual "I" is what differs from the common stock, that is, what cannot be guessed at or calculated, what must be unveiled, uncovered, conquered.
