The Science of Being Rich presents Wallace D. Wattles' systematic exposition of prosperity grounded in constructive thought and disciplined action.

Writing within the New Thought tradition, Wattles argues that wealth is not the result of competition alone but of alignment with universal creative law. He maintains that clear intention, unwavering faith, and purposeful action in a "Certain Way" produce measurable material results. The work rejects anxiety and scarcity thinking in favor of gratitude, clarity, and sustained mental focus.

Unlike later motivational literature, Wattles' treatment is concise and declarative. He frames prosperity as both practical and moral, insisting that increased wealth enables broader service and fuller participation in life. The book's structured argument and disciplined tone influenced generations of twentieth-century success writers and remains a foundational text in early prosperity philosophy.
