Some of the most compelling and enduring creative work of the late Victorian and Edwardian Era came from committed imperialists and conservatives. Their continuing popularity owes a great deal to the way their guiding ideas resonated with modernism in the arts and psychology. The analogy they perceived between the imperial business of subjugating savage subjects and the civilised ego's struggle to subdue the unruly savage within generated some of their best artistic endeavours.

In a series of thematically linked chapters Imperium of the soul explores the work of writers Rudyard Kipling, Joseph Conrad, Rider Haggard and John Buchan along with the composer Edward Elgar and the architect Herbert Baker. It culminates with an analysis of their mutual infatuation with T. E. Lawrence - Lawrence of Arabia - who represented all their dreams for the future British Empire but whose ultimate paralysis of creative imagination exposed the fatal flaw in their psycho-political project.
