When you have wisdom that another person knows that he needs, you give it freely. But when the other person doesn't yet know that he needs your wisdom you keep it to yourself. Food only looks good to a hungry man.
The quote from Orson Scott Card's "Xenocide" suggests that wisdom is most beneficial when it is sought after. If someone is aware of their need for knowledge, sharing it becomes a generous act. However, if the individual is oblivious to their need, it's wise to withhold that information, as it may not be appreciated or understood.
This analogy between wisdom and food emphasizes that understanding and receptivity are crucial for knowledge to be valued. Just as one craves food when hungry, a person must be ready to accept wisdom when they recognize their own lack of insight.
