There is no "final solution" to anything.
As soon as any do-gooder, politician or priest tells you they are going to "end" some chronic problem, you know they are lying. Maybe even to themselves. Steer clear of them.
Of course, there are solutions to certain situations, but never to the context that produces the situations. You can't immanentize the eschaton.
Was that abstract enough for you?
You can defeat an enemy in a war. But you can't end war. That's the kind of thing I mean.
