If you’re in a witchcraft-using community, you hear it a lot. It’s a truncated version of the Wiccan Rede, “An harm ye none, do what thou wilt,” informally interpreted as a binding rule of witchcraft. It isn’t, though — there are plenty of witches of different religions, or none at all, and most of them aren’t bound by it any more than they’re required to follow the Ten Commandments.
Don’t get me wrong, the Rede isn’t a bad thing. Really, it’s pretty liberating… Particularly for people coming to it from more dogmatic religions.
“If it doesn’t hurt anyone, do what you want.” Does your partner consent? Sex isn’t a sin. Does your desire to get tattoos or piercings hurt anyone else? Do as you please. Do you want to carve an image of something? Knock yourself out.
I’m not going to lie, though. Misapplied, it blows.
