Charles Kingsleigh is a fictional character, not a historical author. He is Alice’s father in Tim Burton’s 2010 film *Alice in Wonderland*, where a version of the line about believing the impossible is associated with him. The wording varies in circulation: the film-associated saying is commonly given as “The only way to achieve the impossible is to believe it is possible,” while the added phrase about never giving up may be an expanded version. So the attribution is best understood as a popular association with the character, rather than a securely documented quotation in precisely this form.
The thought joins imagination to persistence. Belief alone cannot make every goal attainable, but it can help us question assumptions about what is out of reach; continued effort turns that openness into action. That combination is why the saying resonates in moments when progress is slow or success seems unlikely. It offers encouragement without suggesting that a wish will come true by itself: first picture a possibility, then keep working toward it. The line also suits Alice’s story, which repeatedly asks her to trust her judgment in a world that refuses to make sense. For readers solving a difficult puzzle, the message feels especially apt: a solution may appear impossible until patience, curiosity, and one more try reveal a way forward.
