The Book of Life : Volume 1, Mind and Body (Barnes & Noble Digital Library)

In all of his writings, Upton Sinclair attempted to establish what is known about life and truth beyond cliche and self-deception. In this 1922 work of nonfiction, an early entry into the self-help genre, Sinclair advises his modern readers on the best ways to improve their bodies and minds so as to cultivate health, wisdom, and happiness.
