ABSTRACT
The author presents three authors in the Aristotelian tradition and his assumption is that, according to the medieval authors, the scope of self-consciousness is limited by the scope of attention. He writes: Chatton here applies his general idea to explain the lack of propositional self-awareness. Peter answers that he hears dogs barking, then he can accept the thought he thereby expresses as true because he is aware of his hearing the barking as the subject of that act, that is, he is objectually aware of the barking with the same degree of attention. Chatton should consider the issue of attention, since it is unclear whether the "reception" of an act includes more than the mere occurrence of it. Suárez also talks about the "change of the power", as when he says that "every cognition occurs by vital attention and change of the power".
