 James Harris and Jacopo Agnesina have both argued that the An Inquiry Concerning Human Liberty was in fact a response to Dr. Clarke and rational theology. They claim that Collins was attempting to demonstrate that determinism follows from Clarke’s first principles (Agnesina 2011, 2018: 105; Harris 2005: 58). Agnesina has also been at pains to argue that Collins’ determinism is a logical and not just a causal determinism.
