Camus talks about something he calls the Absurd. It's about the clash between our desire to find meaning in life and a universe that seems uninterested and silent. This struggle can lead to deep feelings of sadness.

Here are some key points:

1. What is the Absurd?: People naturally want to find a purpose, but the universe doesn't give us clear answers. This can make life feel pretty grim.

2. Feeling Lost: Because of this conflict, people often face a crisis. They feel empty inside and wonder if anything really matters.

3. In Stories: In books like "The Stranger" and "The Myth of Sisyphus," characters show us what it’s like to fight against this feeling of absurdity. Their stories highlight feelings of loneliness and despair.

4. Finding Answers: Camus suggests that instead of turning to old beliefs for comfort, we should accept the Absurd. He encourages us to stand up against the meaninglessness of life. By recognizing the Absurd, people can find their own meaning and freedom, even when things seem hopeless.
