Abstract
This article explores the structural link between international law's long-standing doctrinal commitment to commerce and its inability to act decisively on behalf of the environment. One of the fundamental rights the early authors of jus gentium discovered was the right to engage in commerce. Francisco de Vitoria, Alberico Gentili, and Hugo Grotius each drew on and applied a providentialist theory of commerce. The doctrine held that Providence distributed scarcity and plenty across the earth so that peoples could not be self-sufficient, but would need to go in search of one another in order to acquire what they lacked. Commerce imagined in its pure form of reciprocal, mutually beneficial exchange would be the means to bring separated mankind to friendship. The embrace of the providentialist doctrine by these early exponents of the law of nations, carried forward by Emer de Vattel, set the stage for international law's longstanding commitment to international commerce, viewed (despite all the distortions) as a virtuous activity that tends to the common good. The doctrine's additional legacy was the installation of a view of nature as commodity. The providentialist doctrine of commerce, adopted by the early authors of international law, remains embedded in the structure of international law and cannot easily be dislodged. Until this doctrine is dislodged, however, international law will continue to be hobbled in its ability to address the urgent task of protecting the natural environment.
