Little information survives of Walten's life. He told the court that he was born in Ham, Munsterland, now in Germany. The Dutch scholar Wiep van Bunge suggests that Walten may have been of English descent. He lived in Utrecht until 1685, and from 1688 in The Hague and Rotterdam.
Though influenced by such iconic Enlightenment writers as Descartes and Spinoza in his philosophical thought, Walten denied the latter as his primary political influence and professed to admire Juan de Mariana as the greatest writer on the powers and responsibilities of kings. He was one of the most ardent defenders of the Glorious Revolution, justifying the expedition of William of Orange to England in many pamphlets.
Walten's fate as a controversialist was sealed when his vigorous defense of Balthasar Bekker against the various accusations against him invited a legal prosecution on blasphemy charges against himself. Most damagingly, he had called the Reformed Synod a lunatic asylum ('Een Sothuys van de gekken') for its attack against Bekker. Walten died in prison, probably by suicide, while awaiting trial.
