The Threefold Law

Many Wiccans affirm the Threefold Law, also called the Law of Return or Rule of Three, that whatever one sends out into the world, whether good or ill, returns to the sender multiplied, traditionally threefold. It expresses a moral cause-and-effect built into the nature of things: kindness and harm alike come back upon the doer with added force. The law functions as an incentive to benevolence and a caution against working harm through magic, reinforcing the ethic of the Wiccan Rede with the promise that one's deeds rebound upon oneself.

As with much of Wicca's core teaching, historians of the modern movement, including Ronald Hutton, have traced the Threefold Law's likely origin not to any ancient witchcraft tradition but to mid-twentieth-century occult and theosophical circles, where ideas of a cosmic law of return or moral reciprocity were already circulating well before Gerald Gardner's public presentation of Wicca in the 1950s; the law appears to have been articulated and popularized within the movement's own formative decades rather than inherited intact from a pre-Christian past, a pattern historians find repeatedly across Wicca's claimed lineage of teachings. The law's popularity endures in practice regardless of its actual origin, since for many practitioners its ethical usefulness, as a felt incentive toward care in ritual work, does not depend on how old the teaching turns out to be.
