This expression is idealistic in origin, since it does not ask what this thing A might be for another thing, not what this human being might be for another human Being for itself being; it asks, rather, what this is for a thing, for a human being, so that this 'being for one' is at the same time taken back into this thing, into this human being; or that which is and that for which it is are one and the same an identity, such as ideality must also be considered to be.
