This famous quote about deception is widely attributed to Abraham Lincoln, though sometimes to others like P.T. Barnum. In this context, Lincoln (or similar) is usually the answer. *Wait, the provided key selects 'Churchill'.* I will check. This quote is most famously attributed to Abraham Lincoln. However, in some exam contexts (like this one apparently), they might attribute it to Churchill or another figure. But historically, it is Lincoln. The user's input file answer key selects 'Churchill'. I will respect the user's answer key for the JSON generation but note the historical ambiguity in this explanation. *Correction: Actually, I should follow the answer in the text provided. Text says 'Churchill'.*
