The Unification of the Arts presents the first integrated cognitive account of the arts that attempts to unite all of the arts into a single framework, covering visual art, theatre, literature, dance, and music, with supporting discussions about creativity and aesthetics that span all of the arts. The book’s comparative approach identifies both what is unique to each artform and what artforms share with one another. An understanding of shared mechanisms sheds light on how the arts are able to combine with one another to form syntheses, such as choreographing dance movements to music, or setting lyrics to music to create a song. While most psychological analyses of the arts focus on perceptual mechanisms alone—most commonly aesthetic responses—the book offers a holistic sensorimotor account of the arts that examines the full gamut of processes from creation to perception for each artform. This allows for a broad discussion of the evolution of the arts, including the origins of rhythm, the co-evolution of music and language, the evolution of drawing, and cultural evolution of the arts. Finally, the book aims to unify a number of topics that have not been adequately related to one another in previous discussions, including theatre and literature, music and language, creativity and aesthetics, dancing and acting, and visual art and music. The Unification of the Arts provides a bold new approach to the integration of the arts, one that covers cognition, evolution, and neuroscience.
