Ethics, published (anonymously) by Coornhert in 1586, is a remarkable publication for a number of reasons: it is the first work on ethics written in a European vernacular; it is a mature work, appearing four years before Coornhert's death, and summarizes a lifetime of writing and thinking about the good life; it is considered to be fundamentally pagan because of the absence in Zedekunst of biblical references or any direct mention of Christ. Asked why he did not write about such things as the future establishment of God's kingdom on earth, Coornhert answered: 'Because I have a greater desire to learn how to live well, than to learn how to know much.' This is the first English translation of this important work. It will enhance our insight into the ethical outlook of this prominent freethinker and controversialist of the early Dutch Republic.
