Meaning Crisis
Friedrich Nietzsche seemingly never published this book - yet it is very influential. 

Extreme positions are not relieved by more moderate ones, but by extreme opposite positions. And thus the belief in the utter immorality of nature, and in the absence of all purpose and sense, are psychologically necessary attitudes when the belief in God and in an essentially moral order of things is no longer tenable.
