I enjoyed The Hermetica. This is only the second philosophy book I've read, so I am just learning. The history alone made me interested in this, knowing it may have been written over 5,000 years ago by great Egyptian and Greek philosophers, eventually collated in the Library of Alexandria. Also knowing that eminent figures in history, like Newton, da Vinci, Shakespeare, and Jung praised the philosophies in these writings, I feel very privileged to have been able to read this.
As the summary states, this short book serves as an introduction to Egyptian and Greek philosophies. Even reading this as an atheist, I still feel like I got a lot out of it. I may not agree with a God/Atum/Supreme Being, but I do believe the Universe itself may be the Creator (i.e., pantheism). I do like the idea of life being a circle, that there is no beginning and end. Also that energy/spirit can neither be created nor destroyed. I believe in these concepts too. It also discusses enlightenment - leaving the cycle and becoming one with Atum - as other religions like Buddhism follow.
I would definitely recommend this to anyone interested in an intro to ancient Egyptian and Greek philosophies. The ideas in this seem to form the basis for many modern religions.
