The world is a book and those who do not travel read only one page.

Although widely attributed to Saint Augustine, this aphorism is best treated as a modern proverb about experience and perspective rather than a securely Augustinian statement. Its central idea is that travel functions like reading: it exposes a person to new “chapters” of human life—customs, landscapes, languages, and moral possibilities—thereby enlarging judgment and imagination. Conversely, remaining in one place can narrow one’s understanding, as if one had consulted only a single “page” of a much larger text. The metaphor also implies that the world is intelligible and worth “studying,” and that movement through it is a form of education.
