Voltaire

Voltaire has one of the worst misattribution records of any historical figure, largely thanks to a single famous paraphrase (“I disapprove of what you say, but I will defend to the death your right to say it”) that isn’t his at all — it was written by a biographer summarizing his views, decades after his death.Two more worth a look: “Judge a man by his questions rather than by his answers” and “The most important decision you will ever make is to be in a good mood” — both widely shared under his name, neither one solidly documented as his.
