 We have already considered in some detail Samuel Clarke’s reaction to Collins’ views about emergent properties, personal identity and issues about determinism and free will in the early eighteenth century. The Clarke Collins correspondence of 1707–08 was reprinted twice and referred to many times in the course of the eighteenth century (Martin and Barresi 2000: 33). The conservative reaction to Locke and Collins concerning personal identity and materialism represented by Clarke continued to be maintained by many thinkers in eighteenth century England as well as on the continent. In fact, we can see an on-going debate between the materialists and dualists on these topics all the way through the eighteenth and into the early nineteenth century in England.
