Arminian theologian and biblical scholar. In 1684 he was appointed professor of philosophy at the Remonstrant College at Amsterdam. A champion of freedom of thought and an enemy of dogmatism, he defended the unlimited rights of reason in the domain of faith. He explained the mysteries of the Trinity, Incarnation, and Original Sin on rationalistic lines. He attacked the Mosaic authorship of the Pentateuch and held advanced critical views on the inspiration of Scripture, which he denied altogether in parts of the OT.
