This book illuminates the aesthetically underrated meaningfulness of particular elements in works of art and aesthetic experiences generally. Beginning from the idea of "hooks" in popular song, the book identifies experiences of special liveliness that are of enduring interest, supporting contemplation and probing discussion. When hooks are placed in the foreground of aesthetic experience, so is an enthusiastic "grabbing back" by the experiencer who forms a quasi-personal bond with the beloved singular moment and is probably inclined to share this still-evolving realization of value with others. This book presents numerous models of enthusiastic "grabbing back" that are art-critically motivated to explain how hooks achieve their effects and philosophically motivated to discover how hooks and hook appreciation contribute to a more ideally desirable life. Framing hook appreciation with a defensible general model of aesthetic experience, this book gives an unprecedented demonstration of the substantial aesthetic and philosophical interest of hook-centered inquiry.
