The author speaks in favor of the ethical principles and ideas of the Masons; their insistence upon moral rectitude and good behavior of its members supports the idea that Masonry aims to cultivate the highest virtues of humankind. Such preservation of humanity's greatest strengths is to be applauded: writing in the early 20^th century, the author muses on the social and economic upheavals in a world that has rapidly changed amid industrialization.

Addressing public curiosity on the links between Freemasonry and the ancient lore of the occult is one of Buck's primary aims. The various ancient mysteries dating back to the time when Egypt was under the rule of the Pharaohs are examined. We discover how the modern Masonic principles of liberty, equality and fraternity relate and reconcile with the symbology present in the lodges around the world.

Together with Masonic texts, the author also spoke with Masons and conducted research into ancient civilizations. Thus, Mystic Masonry is an authoritative and fulfilling guide to the subject.
