 These [two] elements are, a hurt to some assignable person or persons on the one hand, and a demand for punishment on the other. … [T]hese two things include all that we mean when we speak of violation of a right. When we call anything a person’s right, we mean that he has a valid claim on society to protect him in the possession of it, either by the force of law, or by that of education and opinion. If he has what we consider a sufficient claim, on whatever account, to have something guaranteed to him by society, we say that he has a right to it. If we desire to prove that anything does not belong to him by right, we think this is done as soon as it is admitted that society ought not to take measures for securing it to him, but should leave it to chance, or to his own exertions. (V 24)
