Yeah, that's what assers are for. Or rather for things that you *think*
are true.

Yes, if you include your assumptions in your definition of "logic".

That may not always be practical. Things that we know (or think) are
true often have *are* true in most cases (otherwise we wouldn't think
so). So the case where the assumption fails may not be easily
reproducable and the more information you can get post-mortem the
better. For example, in C on Linux a failed assertion causes a core
dump. So you can inspect the complete state of the program.
