"Isaac Watts, of course, is a hymn writer in the tradition of Congregationalism who lived in the seventeenth and early eighteenth century. He is very interesting and important because he was also a metaphysician. He knew a great deal about what was, for him, contemporary science. He was very much influenced by Isaac Newton, for example. There are planets and meteors and so on showing up in his hymns very often. But, again, the scale of his religious imagination corresponds to a very generously scaled scientific imagination."
