In "First Meetings in Ender's Universe" by Orson Scott Card, the idea of not sharing valuable insights with those who cannot appreciate them is examined. The phrase "casting pearls before swine" suggests that it can be futile and wasteful to offer what is precious to those who do not recognize its worth. This reflects the notion that wisdom and understanding should be shared selectively, ensuring that meaningful contributions are directed towards those who are capable of valuing them.

Through this lens, the narrative explores the complexities of communication and the challenges of discerning the right audience. The protagonist's experiences serve as a metaphor for the broader struggle of imparting knowledge in a world where not everyone is ready to receive it. Ultimately, the message emphasizes the importance of recognizing the value of knowledge and choosing the right moments and recipients to share it with.
