And he added: "The function of these principles, after all, is simply to provide means by which a court can determine whether [the challenged punishment comports with human dignity. They are, therefore, interrelated, and, in most cases, it will be their convergence that will justify the conclusion that a punishment is 'cruel and unusual.' The test, then, will ordinarily be a cumulative one: if a punishment is unusually severe, if there is a strong probability that it is inflicted arbitrarily, if it is substantially rejected by contemporary society, and if there is no reason to believe that it serves any penal purpose more effectively than some less severe punishment, then the continued infliction of that punishment violates the command of the Clause that the State may not inflict inhuman and uncivilized punishments upon those convicted of crimes."
