A concise early twentieth-century text in which Wallace D. Wattles sets out a theory of health grounded in the disciplined relation between mind, conduct, and bodily condition.

First published in 1910, The Science of Being Well forms part of Wattles's short series on prosperity, character, and physical vitality. In this work, he proposes that health arises not solely from physical causes but from the ordered direction of thought and the consistent regulation of daily habits. His method is prescriptive yet restrained, emphasising clarity of intention, moderation, and the steady alignment of inward and outward life.

Situated within the broader New Thought movement, the text reflects an early twentieth-century attempt to integrate spiritual philosophy with practical concerns of health and well-being. Wattles's prose is direct and economical, presenting his ideas in a structured sequence intended for application rather than speculation. The work remains of interest both as a document of its intellectual moment and as a representative example of applied metaphysical writing concerned with the conditions of a well-ordered life.
