 Accounts of self-consciousness as involving unarticulated constituents, or as implicit in the mode of consciousness, will need to explain how the transition is made from such implicit self-awareness to the explicit representation of the self in first-person thought. One option is to appeal to the idea that certain sources of information are self-tracking or, in Perry’s (2012) words, “necessarily self-informative”. A form of experience is self-tracking if it is a way of coming to know of the instantiation of properties of a certain type and, necessarily, a subject can come to know, in that way, of the instantiation of her own states only. For example, if it is true that a subject can only remember conscious episodes from her own past, then episodic memory is self-tracking. If so, then the subject may legitimately think the first-person thought “I was F”, on the basis of her episodic memory of being F. This account may also be used to explain IEM, since if a form of experience is self-tracking, then it will not be possible for me to know, in that way, that a is F but mistakenly think that it is me that is F on the grounds that I mistakenly believe myself to be identical to a (Perry 2012; Recanati 2012; cf. Campbell 1999a; Martin 1995). Here we have an architectural feature of a given form of experience (that it is necessarily an awareness of oneself) being employed in an explanation of an epistemic feature of self-ascriptions based on such experience (that they are not partly grounded in an identity judgement). If I know, in the relevant way, that a is F, then it must be the case that I am a. On this view, making a first-person judgement grounded in a given form of experience is a matter of articulating the unarticulated self. The experience itself is not explicitly first-personal, representing the self as oneself. Nevertheless, it “concerns” the subject, in that it is necessarily tied to the self (see Musholt 2015: ch. 5 for an alternative account).
