The work, called Edinburgh Lectures on Mental Science, begins with a chapter on spirit and matter, and shows that the fundamental principal of everything is the spirit, the ideal, the purpose and object and matter is simply the form in which this spirit manifests itself. A living spirit, and dynamic force are the central power, and active moving matter is the result. There is no such thing as dead matter, through all the universe, there is motion, continuous, that is guided by a spirit, an ideal power towards Ideal ends. A second chapter describes the control over these spirit forces by higher intelligence and shows that there is a certain atomic as well as psychical intelligence which governs the world in every detail. After describing the unity of the spirit forces, showing that they are under
great laws that regulate their activity, he takes up the subjective and objective minds or the conscious or the subconscious activities of the brain and points out their relation and association, and how far they dominate and influence the details of life.

The chapters on the laws of growth and receptivity, showing that universal mind and individual mind are exact results, and not random changing efforts. Also it is possible to trace them to their causes. In the next chapter intuitions and their indications and meanings and the law which control them, are shown to be realities.
