From the preface:

"Brigham Young was the supreme American paradox, not because he contained elements foreign to American soil but because he united them--the business genius of a Rockefeller with the spiritual sensitivities of an Emerson, the lusty enjoyments of the pleasures of good living with the tenderness of a Florence Nightingale. He was not merely an entrepreneur with a shared vision of America as the Promised Land; he was a prophet with visions of his own and he built beyond himself."
