“Le doute n’est pas une condition agréable, mais la certitude est absurde.” translated non-literally, but clearly as:

“Doubt is uncomfortable, but certainty is absurd.” (Translation cited by Erika Rae in an interview.)

“Doubt is not an agreeable condition, but certainty is an absurd one.” – WikiQuote

An expert is a person who has found out by his own painful experience all the mistakes that one can make in a very narrow field.

I contented myself with whiskey, for medicinal purposes. It helped numb my various aches and pains. Not that the alcohol actually reduced the pain; it just gave the pain a life of its own, apart from mine.
