It’s a common warning that we need to be carefult to not "go too far down the rabbit hole" – that is, we don’t want to get too caught up debating the specifics of some particular definition, or want to avoid going too far off on some tangent. And in almost all cases, this is certainly great advice. But I also think we don’t want to lose sight of the rabbit hole entirely. If the definition of something has such a contested meaning, it must be pretty important. Or at the very least it’s a sign that something interesting is going on. In each season of Beside the Rabbit Hole, I pick a topic that has the potential to go down a definitional rabbit hole, and I walk us right up to the edge. But instead of diving in, we explore that surrounding area and see what issues are at stake and to understand why there’s a rabbit hole to possibly fall into in the first place.
