 From the opposite direction the problem can also be resolved by the denial that the hands should become dirty. An insistence on the inviolability of some moral prescriptions makes the paradox disappear as neatly as the Nielson manoeuvre. If we hold to the prohibition on intentionally killing the innocent, for example, in the face of crises like that supposed by Walzer to necessitate the bombing of German cities in the early phase of World War II, then there are no dirty hands to have. Such a position is often called absolutist. Absolutist positions have been explicitly held by many philosophers, notably Augustine, Aquinas, and Kant, and implicitly perhaps by many more. The position involves complexities that we will examine later.
