The Science of Being Well presents Wallace D. Wattles's philosophy of health as a natural result of right thinking and harmonious living. Best known for The Science of Getting Rich, Wattles extends his system of practical metaphysics in this companion work, exploring how the principles of mental discipline and spiritual alignment can be applied to physical well-being.

According to Wattles, health is not merely a matter of physical treatment but of thought, belief, and conscious cooperation with the creative forces of life. By cultivating constructive thinking, rejecting fear and anxiety, and living in harmony with natural law, individuals can strengthen both body and mind. The book emphasizes the relationship between mental states and physical vitality, encouraging readers to adopt a disciplined outlook that supports lasting health.

First published in 1910, The Science of Being Well became an important text within the New Thought movement. Its ideas about the connection between thought, vitality, and personal responsibility for health continue to attract readers interested in metaphysical philosophy, mind-body relationships, and the broader teachings that made Wattles one of the most influential figures in early twentieth-century self-development literature.
