If I know him, and I think I do, I seriously doubt he chose his nickname casually.
So, Pascal + Coincidences = High School philosophy classes.
If I remember correctly, Pascal is well reknown for his theory of Coincidences in history. He used one example called "Cleopatra's nose": it says that if Cleopatra had an ugly nose, probably Antonio wouldn't have fallen in love with her, this leading to a completely different developement of ancient, and therefore modern, history. It's a way to state that history could be based on smaller events and also on coincidences. A sort of "Butterfly Effect", only in history.
Nothing special, but could really be that someone called Pascal talks about coincidences by coincidence?
Pascal would say it's possible, I would say not, even if I agree with Pascal.
