What is missing in montag's world?

Montag has a lack of meaning in his world. He lives in a world full of superficiality and vapid entertainment. His relationship with his wife Mildred is also superficial. Montag hungers for knowledge, wisdom, and meaning. When Clarisse asks Monag if he is happy, Montag does not know how to answer this question at first. Clarisse stirs a depth of emotion that Montag is not used to. It is only after she leaves that Montag realizes that he is deeply unhappy. The burning of books begins to feel like temporary highs followed by crushing lows. This just has become Montag's life. He goes home to his loveless marriage to find Mildred, his wife, has overdosed on sleeping pills.
