Banez’s Big Problem: The Ground of Freedom
James Dominic Rooney OP
Rooney argues that while Molinism has to deal with the grounding objection, the main Catholic alternative to Molinism, Banezianism, has itself a problem in regards to how creatures can truly freely respond to God’s grace apart from Middle Knowledge. Rooney argues that the eminent Thomist philosopher Reginald Garrigou-Lagrange’s answer is incoherent.
William Lane Craig argues in this essay that while on the surface, it might be easy to lodge a grounding objection against Molinism, such an object, in order to success must come with a truth-maker theory which is not at all obvious or appealing.
