Philosophical Conversions.

I wonder if someone already wrote a book about it, but it would be nice to collect all the stories of philosophical conversions into one nice reference guide. I am thinking about examples like Rousseau’s realization that arts and sciences corrupt morals that came to him on the way to Vincennes in 1749 while he was on the way to visit jailed Diderot – since that resulted in 1751 treatise on arts and sciences, Rousseau’s first work, in a sense, Rousseau’s philosophical life begins at that conversion. Any examples for a future anthology?
