I mean important things such as getting your candidate elected, your
guilty client to be juried innocent, getting people to buy stuff they
don't need and will never need, important things like that. Not
meaningless stuff such as getting an if and only if (fortunately,
contrapositive (as my doctoral father did once - fortunately,
discovered by him when reading the published paper).
