ABSTRACT
Interest in the thought of Hugo Grotius on international law and ethics is justified inasmuch as he attempted to define a theoretical position between an idealism he thought counterproductive and an amoral realism he found unacceptable. Grotius constructed a system in which the moral authority of natural law was combined with the flexibility of human law. This required him to develop a special understanding of the nature and relation of these two types of law. In giving the law of nations, as a product of human will, the authority to suspend provisions of natural law, he provided for a code of international conduct that could permit injustice where necessary, without abandoning moral ideals altogether.
