Some arguments are like mosquitoes. They get slapped and well and truly squashed – unambiguously defeated in plain sight for all to see, obviously crushed. The smeared body is witnessed. But then as soon as you try to relax again, that familiar whining sound fades in again. You think, Didn’t I just squash you? Yes you did, and it’s back.
As I’ve mentioned elsewhere, objections to divine command theories of ethics are a good example of arguments like this. But they’re not alone. Another is the Lottery Fallacy Fallacy. I know, calling something a “fallacy” is a bit of a rhetorical device, but I use the term because the argument that I want to rebut – again – is one that trades on using that word for rhetorical effect, so my use of the word twice must surely double the effect!
