Abstract:
In a recent paper, Brogaard (2011) presents counter-arguments to the conclusions of an experiment with blindsight subject GR. She argues that contrary to the apparent findings that GR's preserved visual abilities relate to degraded visual experiences, she is in fact fully unconscious of the stimuli she correctly identifies. In this paper, we present arguments and evidence why Brogaard's argument does not succeed in its purpose. We suggest that not only is relevant empirical evidence in opposition to Brogaard's argument, her argument misconstrues necessary criteria to decide whether a conscious experience is visual or not visual.
