Wallace Delois Wattles (1860–1911) was an American New Thought writer predominantly recognized for his work, 'The Science of Getting Rich,' a treatise that combines philosophical inquiry with practical steps to achieve prosperity and success, which is included in 'The Science of Wallace D. Wattles: Complete Trilogy.' Emerging from humble beginnings, Wattles' writing was extensively influenced by the New Thought Movement, an ideology premised on the idea that positive thinking can produce tangible results. He was a methodical thinker who delved into themes of health, wealth, and personal growth, creating a compendium of knowledge that appealed to those eager to harness their inner potential. Strategically congruent with the works of contemporaries like William Walker Atkinson, Wattles' literary style was straightforward and prescriptive, aimed to foster self-improvement and the law of attraction. His contributions are particularly resonant in the domains of success literature and self-help, reflecting a lifetime committed to understanding and articulating the principles of achievement and the effects of constructive thought patterns on personal advancement. His 'Complete Trilogy' not only illustrates his most notable ideas but also serves as an enduring legacy of an author who sought to transform life through the power of thought.
