This study investigates the evolution of William Blake's philosophical and artistic framework, specifically focusing on how his concept of energy informs his creative output. Morton D. Paley, a noted scholar of Romantic literature, utilizes a chronological analysis of Blake's poetry and visual art to trace the development of his thought. By examining the interplay between Blake's internal intellectual shifts and the external socio-political climate of the late 18th and early 19th centuries, Paley constructs a comprehensive argument regarding the coherence of Blake's complex mythology.

Scholars frequently cite this work as a foundational text for understanding the intellectual underpinnings of Blake's mythology. Readers often note the academic density of the prose, which requires a significant familiarity with Blake's primary texts to fully appreciate the depth of Paley's analysis.
