Many Wiccans also seek to cultivate a set of eight virtues mentioned in Doreen Valiente's "Charge of the Goddess", these being mirth, reverence, honour, humility, strength, beauty, power, and compassion. In Valiente's poem, they are ordered in pairs of complementary opposites, reflecting a dualism that is common throughout Wiccan philosophy. Some lineaged Wiccans also observe a set of Wiccan Laws, commonly called the "Craft Laws" or "Ardanes", 30 of which exist in the Gardnerian tradition and 161 of which are in the Alexandrian tradition. Valiente, one of Gardner's original High Priestesses, argued that the first thirty of these rules were most likely invented by Gerald Gardner himself in mock-archaic language as the by-product of inner conflict within his Bricket Wood coven – the others were later additions made by Alex Sanders during the 1960s.
