Neville's physical argument for the necessity of resistance, always given as a list. I couldn't leave the platform unless I was opposed, the car couldn't move unless opposed, the bird couldn't fly unless opposed, the plane couldn't take off unless opposed, the fish couldn't swim unless opposed. Everything in this world must be opposed in order to move, so God sets up that opposition - and then in me, the dead, he sets up the opposition and then he moves. What the list is for changes with the lecture, and the three uses are worth keeping in view. At 1273 it is reassurance in the middle of a technique: no power in this world can stop it, the very opposition will be aiding, so don't be afraid of opposition, they're simply moving you out. At 1828 it is the ground of forgiveness: all those who seemingly tried to oppose you on your forward motion were aiding you and you didn't know it, therefore forgive them all in the end. Here it is theodicy - God sets up his own opposition because without it not a thing could happen, and growth is forever, so there is no last opposition either. At 1350 the same point is made abstractly through a frame of reference: I move only relative to something. About four lectures.
