 It is difficult to know for certain why Ockham abandoned the concept of synderesis. Michael Baylor, however, has suggested two possibilities. The first is that, as we have seen, synderesis was regarded by Ockham’s predecessors, like Aquinas, as an inborn habit. But for Ockham, rational agents only come to possess habits by acquiring them, and they can only acquire them by doing the relevant acts repeatedly. The notion that a habit could be innate, then, would have seemed incoherent to Ockham (Baylor 1977: 78; Fuchs 1952: 5–6).
