Acting without regard to law, ethics, or the rights of others.
The term licentiousness is often used interchangeably with lewdness or lasciviousness, which relate to moral impurity in a sexual context.
LICENTIOUSNESS. The doing what one pleases without regard to the rights of others; it differs from liberty in this, that the latter is restrained by natural or positive law, and consists in doing whatever we please, not inconsistent, with the rights of others, whereas the former does not respect those rights. Wolff, Inst. Sec. 84.
