At the end of chapter four in The Sun Also Rises, Jake is ruminating on Brett and their frustrated relationship. He says, “It is awfully easy to be hard-boiled about everything in the daytime, but at night it is another thing.”
Why is it that night brings out our fears, our insecurities, our doubts? What brings out the real us? Does darkness reveal who we really are, or does the morning light show our true nature? Why the polarity? Or does the fact that the polarity exists show something about us? If it is well with our souls, are we impervious to the dark shadows and what they reveal?
The night, not the bright light of day, reveals our true nature. We can manage to hold up under the light of day because we trust it will blind others to what ails our souls. Sleep is not hindered by a clear conscience and a settled soul.
