Samuel Bourn the Younger (1689 –22 March 1754) was an English dissenting minister. He was an English presbyterian preaching on protestant values learned from the New Testament. Through his published sermons, he entered the theological debate that flourished around the Arian controversy, and the doctrinal question as to Man's essential nature. He contested the Deism of the Norwich rationalists in the early enlightenment, and challenged the Trinitarian conventional wisdoms about the seat of humanity and its origins.
