Mysteries of the Unknown: Ancient Wisdom and Secret Sects

The chapters on Free Masonry and The Golden Dawn were pretty informative. I think my big takeaway about these sects was not so much that they are dark subcultures that secretly control the world, but rather, that well-to-do people will come up some really goofy extracurricular activities just to feel out of the ordinary (the 19th century equivalent of a polar plunge or costumed 4K fun-run). Oh, and Aleister Crowley was a big, pervy jerk.
