Joseph Glanvill (1636 – 4 November 1680) was an English writer, philosopher, and clergyman. Not himself a scientist, he has been called "the most skillful apologist of the virtuosi", or in other words the leading propagandist for the approach of the English natural philosophers of the later 17th century. In 1661 he predicted
He was raised in a strict Puritan household, and educated at Oxford University, where he graduated B.A. from Exeter College in 1655, M.A. from Lincoln College in 1658.
Glanvill was made vicar of Frome in 1662, and was a Fellow of the Royal Society in 1664. He was rector of the Abbey Church at Bath from 1666 to 1680, and prebendary of Worcester in 1678.
He was a Latitudinarian thinker. Latitudinarians generally respected the Cambridge Platonists, and Glanvill was friendly with and much influenced by Henry More, a leader in that group where Glanvill was a follower. It was Glanvill's style to seek out a "middle way" on contemporary philosophical issues. His writings display a variety of beliefs that may appear contradictory. There is discussion of Glanvill's thought and method in Basil Willey's Seventeenth Century Background (1934).
He was the author of The Vanity of Dogmatizing (editions from 1661), which attacked scholasticism and religious persecution. It was a plea for religious toleration, the scientific method, and freedom of thought. It also contained a tale that became the material for Matthew Arnold's Victorian poem The Scholar Gipsy.
