This study offers an original and innovative collection of fresh approaches to the investigation of the concept of ugliness. It is divided into three parts: the idea of ugliness; Kantian conceptions of the ugly; and ugliness and art. The papers in all three sections deal with problems in the way that aesthetics has understood the concept of the ugly, in aesthetic experience, in fine art, and in contrast with the beautiful. These are new papers from a range of scholars from diverse philosophical backgrounds, and use the most recent literature in their areas of expertise. There is no other book available that collects the latest research in this field, and, as such, it will be a key contribution to recent and growing theoretical interest in the place of the ugly in aesthetics.
