The book was great. A very sobering and rational surveying of what was known about the actual Bavarian organisation Illuminati, and what accusations and rumours thereafter surfaced regarding the Illuminati. Illuminati was a fraternal society in the 18th century, the known members of which are referred to as Illuminatus, and Illuminoids are anybody (basically after the 18th century) that are called into suspicion for being involved in the Illuminati or for having Illuminati-like behaviour. This book seems too old to note that modern occult societies OTO and AMORC have grades/levels that use the word "Illuminati" in their titles, and the "IOT" uses "Illuminates" in their name. It's really difficult to say which illuminations across time and space have a direct lineage to one another, and who's simply incorporated the word "Illuminati" or the metaphor of "illumination" into their material.
