There are certain kinds of evidence that support the identification of self-consciousness as an essential component of consciousness. One is that you are abl to form a clear picture of whatever it is that have just been doing, whether you were deliberately watching yourself or not. Another is that in the presence of others to a greater or lesser degree your awareness is doubled into a sense of how you are for yourself and how you are for the other, and these two faces can echo back and forth. Yet another is that you can tell stories about yourself, stories set in the past or the future, stories in which you are a character, stories that you can creatively modify with certain limits. None of these is a primary self-consciousness, where what-is-aware is turned back on itself, instead they are all mediated by representations and must be interpreted as self-consciousness. The case they make is that without primary self-consciousness they could not be as they are. This argument fails as it tries to use representations to point to what is prior to representation. In the end you do not know if you are self aware or not!
