C.S. Lewis on being an agent as well as a patient

"He looked back on that time as on a nightmare, on his own mood at that time as a sort of sickness. Then all had been whimpering, unanalysed, self-nourishing, self-consuming dismay. Now, in the clear light of an accepted duty, he felt fear indeed, but with it a sober sense of confidence in himself and in the world, and even an element of pleasure. It was the difference between a landsman in a sinking ship and a horseman on a bolting horse: either may be killed, but the horseman is an agent as well as a patient." - C.S. Lewis, Out of the Silent Planet, 86-87
