High Sorcerous Arte versus Traditional Witchcraft of the Britons. Some believe they are incompatible, but that may be a narrow view. Trad witchcraft, which to an extent incorporates ritual magic into its paradigm, is enacted on a lower plane (what Crowley calls Low Magick), e.g., European folk magic, hoodoo. Ceremonial or High "Magick" is an extension of ritual into the theurgistic realm. Some systems draw heavily from both.
