The Harmonial Philosophy represents an extensive collection of the wisdom of Andrew Jackson Davis, one of the first prolific authors in the field of spiritualism and hermetic science. A supreme compendium of Davis's thinking, this work comprises eight books. Each of these contains a revelatory analysis of a realm of spiritualist thought, beginning with considerations of the divine God and His relation to human intellect and thought processes. This examination of the Creator is followed with a detailed look at the interplay between the cosmos, spiritual forces, and the very genesis of mankind. Davis turns to the qualities of human beings, in particular the mental states which characterize our existence. The ability of our mind to change and adapt to conditions, and understand concepts such as objective truth, personal liberty and spiritual needs is expounded upon in successive chapters. Such knowledge feeds into the concept of man's immortal soul, and the soul's interaction with the spiritual worlds beyond our own. In the later books, we delve deeper into the spiritualist approach to life; how the spiritual forces affect change within the lives of mortals, and how we can attune ourselves by assimilating principles of religion and theology.

Such knowledge involving the great prophets and philosophers of the past opens our spiritual senses and allows us to comprehend threads of humanity expressed across realms, space and time. This edition of The Harmonial Philosophy includes all of the original notes as well as a helpful bibliography appended by the author.
