["The Journal of Creative Behavior, Volume 60, Issue 2, June 2026. ", "\nABSTRACT\nOne hundred years after the publication of The Art of Thought (1926), Graham Wallas remains widely cited yet poorly understood. His stages of preparation, incubation, illumination, and verification continue to circulate as a foundational model of creativity, even as the life that gave rise to them has largely faded from view. This article argues that this disconnect reflects a deeper problem in creativity research: the tendency to separate ideas from the lives that sustain them. Drawing on Wallas's writings and contemporaneous accounts, the article reconstructs him as a person shaped by moral seriousness, disciplined effort, intellectual independence, and a sustained commitment to education and social reform. His stages are reinterpreted not as a detachable schema, but as one expression of an ethical orientation toward thought grounded in judgment, responsibility, humane insight, and endurance. The article concludes by asking what is lost when creativity is treated as a model rather than a way of living with ideas.\n"]
