 Abner explains in the same way the meaning of possibility and accident. Things are only possible in their relation to themselves. In relation to the entire world and its causality, everything is truly determined. Accidents are only accidents relative to the seeming unlikelihood of their occurrence. However, relative to all the causal processes of the world, we see that even in the most unusual of circumstances the occurrence of what appears to be an accident in fact had to happen. In short, there are no accidents (according to the popular meaning of accident) for Abner.
