Kundera reflects on the unpredictability of life, illustrating the necessity of embracing uncertainty. He uses the metaphor of a child to highlight this idea, suggesting that just like a child's future is unknown, so too is the path of life. Accepting life's unpredictability allows individuals to fully engage with their experiences and not live in fear of what is to come.

The metaphor of someone who cannot swim yet chooses to rest on the shore signifies a limited existence. By avoiding the depths of life's uncertainties, one restricts their potential and growth. Kundera encourages readers to dive into the complexities of life, illustrating that true fulfillment comes from accepting and experiencing the unknown rather than shying away from it.
