The quote by Walker Percy, "Being uneducated is no guarantee against being obnoxious," suggests that ignorance alone does not determine a person's behavior or character. It implies that even those who may be well-educated can perpetrate negativity or rudeness. Education does not inherently cultivate virtues like respect or kindness; instead, these qualities must be developed through personal growth and self-awareness.

This observation highlights the complexities of human behavior. It serves as a reminder that one's educational background does not excuse poor conduct. Regardless of knowledge or academic achievement, individuals have a responsibility to act with consideration toward others. Ultimately, the quote challenges the notion that education alone is sufficient for good character and emphasizes the importance of personal accountability in social interactions.
