Book excerpt: Through an interlocking series of texts and images, this work explores how extreme sensations such as wonder, misery, ecstasy and rage have been portrayed at different moments in Western culture. Moving across multiple fields of creative endeavour and intellectual inquiry - from classical artefacts to Chicano art, political protest to operatic performance, Rene Descartes's writings on the soul to the Internet's digitised flesh - it reveals how the passions have elicited, eluded and transformed the act of representation.
