He was no longer quite sure whether anything he had ever thought or felt was truly his own property, or whether his thoughts were merely a common part of the worldโs store of ideas which had always existed ready-made and which people only borrowed, like books from a library.
Milan KunderaWhat 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.
