 Joseph Priestley (1733–1804) was sufficiently impressed with Collins’ Philosophical Inquiry Concerning Free Will to arrange the publication of a new edition of that work. Priestley also held that matter can think, but his views were based on a different conception of matter than the one which Collins and Clarke shared. Priestley had an active conception of matter derived from Boscovich. Priestley was also impressed by Collins’ work on the prophecies (Yolton 1983: 108–113).
