To be called a copy, to be called unreal, is thus one way in which one can be oppressed. But consider that it is more fundamental than that. For to be oppressed means that you already exist as a subject of some kind, you are there as the visible and oppressed other for the master subject as a possible or potential subject. But to be unreal is something else again. For to be oppressed one must first become intelligible. To find that one is fundamentally unintelligible (indeed, that the laws of culture and of language find one to be an impossibility) is to find that one has not yet achieved access to the human. It is to find oneself speaking only and always as if one were human, but with the sense that one is not. It is to find that one's language is hollow, and that no recognition is forthcoming because the norms by which recognition takes place are not in one's favour.
