Looking for a quote

[livviebway.livejournal.com]

I'm looking for a quote about the Revolution and Google is being remarkably unhelpful, considering I thought it was a fairly famous quote.  If anyone can give me the exacting wording and author of this quote that would be incredibly helpful.

It's something like, referring to the French Revolution, "Never was any event so inevitable yet so completely unexpected."

Thanks!  

EDIT: Ah ha.  De Tocqueville: "Never was any event so inevitable yet so utterly unforeseen."
