Grotius’ Imago Dei anthropology: grounding Ius naturae et gentium

In the standard account Hugo Grotius secularized international law by grounding it on human nature. This chapter argues we should not stop at the standard account, but rather should dig deeper and examine the theological anthropology grounding Grotius’ ideas on the law of nature and nations. With some attention for the influence of both (neo-)scepticism and (neo)stoicism in analyses of Grotius’ understanding of human nature and natural law, this chapter examines Grotius’ ideas through the lens of the Christian theological notion of imago Dei—the idea that human beings are different from other animals in that they are created in ‘the image and likeness of God’. The chapter relates the concept of the imago Dei briefly to the early seventeenth-century theological and political debates in the Dutch Republic and discusses the Arminian interpretation of the imago Dei along the lines of three dimensions generally set apart: ontological, teleological, and functional.
