The harm principle is articulated in John Stuart Mill's On Liberty. Mill argues that the sole purpose of law should be to stop people from harming others and that should people want to participate in victimless crimes, crimes with no complaining witness, such as gambling, drug usage, engaging in prostitution, then they should not be encroached in doing so.

Mill defines the harm principle in Chapter One as follows:

The object of this Essay is to assert one very simple principle, as entitled to govern absolutely the dealings of society with the individual in the way of compulsion and control, whether the means used be physical force in the form of legal penalties, or the moral coercion of public opinion. That principle is, that the sole end for which mankind are warranted, individually or collectively, in interfering with the liberty of action of any of their number, is self-protection. That the only purpose for which power can be rightfully exercised over any member of a civilized community, against his will, is to prevent harm to others. His own good, either physical or moral, is not sufficient warrant. He cannot rightfully be compelled to do or forbear because it will be better for him to do so, because it will make him happier, because, in the opinion of others, to do so would be wise, or even right... The only part of the conduct of anyone, for which he is amenable to society, is that which concerns others. In the part which merely concerns himself, his independence is, of right, absolute. Over himself, over his own body and mind, the individual is sovereign.

The harm principle is in part the basis for certain political stances of the United States Constitution and Libertarian Parties.
