C.S. Lewis writes "Learning in Wartime" to illustrate the importance of continuous learning, specifically, during times of conflict. When difficulties come our way, we should not stop in our tracks and wait for it to pass. Instead, we should be viewing difficult moments in our lives as another opportunity to gain more knowledge and grow from it. Lewis says, "The war creates no absolutely new situation: it simply aggravates the permanent human situation so that we can no longer ignore it." In other words, war does not create abnormalities, but instead, it enhances the problems that people have already been struggling with.

Lewis writes about three enemies that war brings: excitement, frustration, and fear. With over excitement comes our inability to be focused on what God would want us to fulfill. Next is frustration. By attempting to accomplish and do everything, the natural feeling would result in frustration due to the fact that in life, no one ever finishes everything. There is always something that will be accomplished at the end of life. Lastly, there is no reason to be afraid of death. It is inevitable that death will eventually come towards our direction since all humans will eventually die.

C.S. Lewis gracefully alludes to wartime, human nature, and Christianity in his writing of "Learning in a Wartime."
