In Gardnerian Wicca, these tradition-specific teachings demand thought before action, especially magical action (spell work). An individual or a coven uses these guidelines to consider beforehand what the possible ramifications may be of any working. Given these two ethical core principles, Gardnerian Wicca hold themselves to a high ethical standard. For example, Gardnerian High Priestess Eleanor Bone was not only a respected elder in the tradition, but also a matron of a nursing home. Moreover, the Bricket Wood coven today is well known for its many members from academic or intellectual backgrounds, who contribute to the preservation of Wiccan knowledge. Gerald Gardner himself actively disseminated educational resources on folklore and the occult to the general public through his Museum of Witchcraft on the Isle of Man. Therefore, Gardnerian Wicca can be said to differ from some modern non-coven Craft practices that often concentrate on the solitary practitioner's spiritual development.
