The main purpose of this paper is to analyze some different explanatory models of self - knowledge, belonging to Contemporary analytic philosophy. As a starting point, I will focus on self-ascriptions of mental states of the likes of [quot ]I have a headache[quot ], [quot ]I am thinking about my son[quot ], [quot ]I desire to shock my father[quot ], namely, the so-called [quot ]avowals[quot ]. In the first part, I will point out what I take to be the set of characteristics of avowals that any theory about self-knowledge should account for. In the second part, I will present and contrast with one another the main theoretical explanatory models that have been put forward to give the required account.
