 Additional arguments for metacognitive accounts of consciousness appeal to their alleged explanatory value. For example, Rosenthal argues that the fact that our conscious states comprise the part of the our minds available for our first-person report is best explained by supposing they are always objects of thoughts of the kind such reports would express. And advocates of higher-order perception or inner sense versions of the metacognitive approach argue that such views best explain our capacity to attend to our own experience introspectively (Lycan 2004), and to form “recognitional concepts” of our own sensory states (Carruthers 2004).
