A Note on Fake Lewis Quotes
Some beloved lines credited to Lewis cannot be found in his books or letters. “You are never too old to set another goal or to dream a new dream” is the most famous example; scholars have not traced it to his writings. The same caution applies to “You don’t have a soul. You are a soul. You have a body.”
Sharing real lines protects both Lewis and your readers. The genuine catalogue is rich enough that you will never run short. For more reflective reading, these life quotes inspiration and self-love quotes collections sit well beside this one.
How to Use These Quotes
Read one line slowly, then find it in its book if you can. Lewis rewards context. A Narnia line suits a card for a friend who grew up with the books, while a line from A Grief Observed belongs in a private message, not a public post. In a journal, copy the quote that unsettles you and write a few honest lines underneath.
