More on Goetic Magic: Three 20th century developments

In a previous post, now a couple of months ago, I wrote about the distinction between goetia and theurgy in ceremonial magic. I tried to trace the development of the distinction, in very broad strokes, from neo-platonic discussions in late antiquity through the renaissance rehabilitation of magic, through to 19th century occultism. This was part of developing my thoughts for an article on «Goetia in Modern Western Magic», the deadline for which has now (as it usually goes with academic anthologies) been postponed. This gives me opportunity to try out some more ideas here.
