I’ve seen some libertarians describe their ethic as, “Do what you will…but pay the price.”

Frankly, that is not a prescription at all. It simply describes consequences.

In ethical paganism, this would be considered incomplete, as the conclusion of the famous Wiccan Rede demonstrates:

“Where the rippling waters go, cast a stone, the truth you’ll know.
When you have and hold a need, harken not to others greed.

With a fool no season spend, or be counted as his friend.
Merry Meet and Merry Part, bright the cheeks and warm the heart.

Mind the Three-fold Laws you should, three times bad and three times good.
When misfortune is enow, wear the star upon your brow.

Be true in love this you must do, unless your love is false to you.

These Eight words the Rede fulfill:

“An Ye Harm None, Do What Ye Will”

An Ye Harm None.

The  simple omission of this phrase has tragic consequences for people’s understanding of ethical practice. Worse yet, they enter a path of solipsism, narcissism, and even criminality, under the delusion that they’ve discovered a new moral law.

Of course, what constitutes harm is debatable….
