William Derham was an Anglican clergyman and disciple of Isaac Newton whose widely-read Astro-Theology: or, A Demonstration of the Being and Attributes of God (1715) promoted pluralism by arguing that God would not have created habitable worlds without them actually being inhabited. Derham avoids, however, discussing the possible nature of extraterrestrials, pointing his readers instead to the speculations of Huygens in his Cosmotheoros.
