Erik Davis is teaching another class at MLA called Gnosis Now! from February 23 - April 5 2009.
Gnosis Now! (from MLA course page)
Gnosticism is one of the most potent, complex, and misunderstood elements of western esoteric spirituality. Rooted in the apocalyptic era of early Christianity, gnostic mysticism animates hermeticism, alchemy, and magick, and has profoundly influenced modern pop culture as well (Philip K. Dick, The Matrix, even Scientology). Because gnosticism is rooted in direct experience of the divine, it remains open to many different interpretations; scholars bicker about it constantly.

This class proposes to study a few of the most accessible and transformative gnostic texts, both ancient and modern, and to bring their tricky wisdom to bear on the state of consciousness today. In addition to online discussion threads, the course will feature weekly podcasts from Erik Davis, a celebrated speaker, as well as a few group voice-over-IP chats. Modestly-sized texts will include ancient gnostic gospels as well as accessible scholarly interpretations and modern short stories.
