In her book "Unless," Carol Shields explores the theme of intellectual confidence among bookish individuals. These readers, who may struggle with social interactions, believe that by engaging with written prose, they can grasp complex ideas and nuances. This mindset often leads them to overestimate their ability to understand and navigate life's subtleties through literature alone.

Shields highlights the irony of this belief, suggesting that while the written word can enhance understanding, it doesn't always translate to real-world wisdom. The notion that mastery can be achieved solely through reading underscores the limitations faced by those who find refuge in books, illustrating a disconnect between theoretical knowledge and practical experience.
