In the sentence below, is "without" serving the same function that "If" usually does?
Life wouldn't be the same without good friends.
I was thinking it could be rewritten as
Life wouldn't be the same if we didn't have good friends.
So can we consider "without" as a conditional form?
In this case, why not? But where's the condition in the following sentence?
He is a knight without a sword.
