Wiccan morality is expressed in a brief statement found within a text called the "Wiccan Rede": "An it harm none, do what you will." ("An" is an archaic word meaning "if".) The Rede differs from some other well-known moral codes (such as Christian or Islamic notion of sin) in that, while it does contain a prohibition, it is largely an encouragement to act freely. It is normally considered that the prohibition against harm also covers self-harm. It is also worth noting that "Rede" means advice, as such it is not so much a law that must be followed as advice that it is recommended one follows - not following it would be considered folly more than rule-breaking, though for a group that calls itself "Wise" it follows that such folly would be strongly avoided.
