A concise exposition of health as the outward expression of ordered thought and disciplined living within the New Thought tradition.

In The Science of Being Well, Wallace D. Wattles sets out a method for the attainment and maintenance of physical well-being grounded in the alignment of thought, conduct, and bodily function. The work proceeds from the premise that health is not merely the absence of illness but a condition sustained through the consistent direction of the mind and the proper use of the body. Wattles presents a structured approach, emphasising clarity of purpose, regularity of action, and the cultivation of constructive mental habits.

First published in the early twentieth century, the text forms part of Wattles's broader series of works addressing prosperity, personal development, and well-being. His method is direct and instructional, avoiding speculation in favour of clearly stated principles intended for practical application. The work remains a representative example of New Thought writing concerned with the integration of mental discipline and physical vitality.
