This book investigates the nature of visual experience by applying semantic analysis to the language used to describe perceptual states. Wylie Breckenridge examines the linguistic structure of 'look' sentences to construct a formal theory regarding the character of visual perception. By analyzing how these descriptions function, the author provides a rigorous defense of the adverbial theory of perception, challenging prevailing representationalist accounts.

Scholars in the philosophy of mind recognize this work as a significant contribution to the ongoing debate between representationalism and adverbialism. Readers frequently note the technical density of the prose, which requires a strong background in analytic philosophy to fully grasp the author's arguments.
